Definitions
- the invention relates to a knotless suture anchor system for attaching soft tissue to hard bone, and to methods for attaching soft tissue to hard bone.
- Soft tissues such as ligaments, tendons and muscles
- ligaments and tendons are attached to a large portion of the human skeleton.
- many ligaments and tendons are attached to the bones which form joints, such as shoulder and knee joints.
- a variety of injuries and conditions require attachment or reattachment of a soft tissue to bone. For example, when otherwise healthy tissue has been torn away from a bone, surgery is often required to reattach the tissue to the bone to allow healing and a natural reattachment to occur.
- a number of devices and methods have been developed to attach soft tissue to bone. These include screws, staples, cement, suture anchors, and sutures alone. Some of the more successful methods involve use of a suture anchor to attach a suture to the bone, and tying the suture in a manner that holds the tissue in close proximity to the bone.
- the tissue may be attached to the bone during open surgery, or during closed (e.g., arthroscopic) surgical procedures. Closed surgical procedures are preferred since they are less invasive and are less likely to cause patient trauma. In a closed surgical procedure, the surgeon performs diagnostic and therapeutic procedures at the surgical site through small incisions, called portals, using instruments specially designed for this purpose. One problem encountered in the less invasive, closed surgical procedures is that the surgeon has significantly less room to perform the required manipulations at the surgical site. Thus, devices and methods are needed which will allow a surgeon to effectively and easily attach tissue to bone in the small spaces provided by less invasive surgical procedures.
- Knotless suture anchor systems have been developed for use with closed surgical procedures, and U.S. Pat. No. 5,569,306 provides one example of such a system.
- a further knotless suture anchor and system is disclosed in U.S. Pat. No. 5,782,864.
- such systems can be limited to use only with certain types or shapes of tissue, or to use with certain anatomical structures. Proper attachment of soft tissue requires that it be placed in the anatomically correct position to promote optimal healing.
- some conventional knotless suture anchor systems may require, in order to attach a broader array of tissue shapes to bone, that the suture anchor pass though the tissue to be attached. This is undesirable because it unnecessarily irritates the injured tissue and it requires opening a much larger hole in the tissue.
- the present invention provides a system for anchoring tissue to bone including a suture anchor, a first suture loop attached to the suture anchor, a suture needle and a second suture loop attached to the suture needle and interlocked with the first suture loop.
- the second suture loop may be formed by attaching two free ends of a length of suture thread directly to the suture needle, or by attaching the two free ends within a suture closure which may then be attached to the suture needle.
- the suture anchor is entirely bioabsorbable.
- a method is also provided by which a detached tissue may be securely attached to bone in an anatomically correct position without the need to tie a knot.
- the system includes a suture anchor having a first, leading end, a second, trailing end, and two opposed sides between the first and second ends.
- the second end has a flared portion that renders the suture anchor asymmetrical in a plane that includes the longitudinal axis.
- the first suture loop is attached at a position between the first and second ends of the suture anchor and is interlocked with the second suture loop.
- the second suture loop is attached to a trailing end of the suture needle.
- the asymmetrical shape of the suture anchor assists in securing the anchor within bone.
- the anchor When tension and deflection by the inserter is applied to the suture anchor, after the anchor is positioned within bone, the anchor undergoes a toggling action, or rotation which results in the anchor being oriented in a direction that is not parallel with the longitudinal axis of the anchor-seating bore. This toggling of the anchor causes the anchor to become lodged within the bone.
- the anchor can be firmly embedded within bone without the need for ancillary anchoring structure such as arcs.
- the second suture loop is formed using a suture loop closure and is attached to a hollow suture needle by means of a slot provided in a wall of the hollow needle.
- This embodiment may also employ an actuator, disposed within the hollow needle, which can be selectively deployed to disengage the second suture loop from the needle.
- the hollow needle used with this embodiment preferably is part of an elongate tool, such as a suture inserter, that is useful in closed surgical procedures.
- the hollow needle typically forms the distal end of such a tool.
- the system may be used in a method wherein the suture needle and the attached second suture loop are passed through a detached segment of tissue.
- the second suture loop is pulled through the detached tissue until a portion of the interlocked first suture portion of the first suture loop is seated within a suture thread-engaging groove at the first end of the anchor.
- the anchor is then tapped into a predrilled bore in a portion of hard bone. Once inside the bone, tension is applied to the anchor by sutures, causing the anchor to toggle such that it is no longer oriented in a direction parallel to the longitudinal axis of the bore, and the flared portion of the anchor engages and is wedged into the wall of the bore.
- the suture anchor is thus stabilized in an interference fit within the bore, and the detached tissue is thereby attached to the bone in the desired position.
- suture needle is used herein to encompass both conventional suture needles, used in open surgical procedures, as well as suture needles that may form a hollow, distal end of an elongate tool useful with closed surgical procedures.

- FIG. 1 a system 10 for anchoring tissue to bone in accordance with the invention is shown.
- the system includes a suture anchor 12 , a first suture loop 14 attached to the suture anchor 12 , a suture needle 16 and a second suture loop 18 attached to the suture needle 16 .
- the first suture loop 14 and the second suture loop 18 are interlocked with each other.
- the system may also include an anchor inserter tool 20 .
- the suture anchor 12 has a first, leading end 22 and a second, trailing end 24 .
- the first, leading end 22 tapers, while the second trailing end 24 flares out at one side, rendering the suture anchor asymmetrical in a plane that includes the longitudinal axis 11 .
- the suture anchor 12 has two flat, opposed sides 26 , 28 between the first and second ends 22 , 24 to allow for suture thread to easily pass back and forth.
- sides 26 , 28 are shown as flat, it is understood that they may be otherwise shaped or contoured. For example, they may be curved or rounded.
- the sides 17 , 19 adjacent sides 26 , 28 may be curved, rounded, or flat.
- the exemplary suture anchor 12 additionally comprises a suture thread-engaging groove 23 at the first end 22 for seating portions of the first loop of suture thread 14 .
- the second, trailing end 24 includes a flared portion 25 , which is integral with side 17 .
- flared portion 25 is located between the two opposed flat sides 26 , 28 , but it could be located anywhere on the suture anchor.
- Flared portion 25 may include a sharp edge for penetrating into hard bone, such as cortical bone. Flared portion 25 may also include a knife-like edge (not shown) with a rounded proximal end to promote bone penetration.
- suture anchor 12 may include surface features (not shown) to promote secure seating within bone and to prevent the anchor 12 from backing out of the bone once inserted.
- the flared portion 25 preferably is formed only on one side of the suture anchor 12 .
- the flared portion results from a gradual widening of one side of the anchor.
- the flared portion causes the suture anchor to be about 0.5 to 1.5 mm, preferably 1.0 mm, wider than it would be without the flared portion.
- the flared portion 25 has a breadth dimension (B) that is consistent with the breadth of side 17 , with which it is integral.
- the breadth (B) of the flared portion 25 is preferably about 0.3 to 1 mm.
- the suture anchor 12 may be constructed from suitable metals or polymers known to those of ordinary skill in the art.
- suture anchor 12 is fully bioabsorbable and is constructed from a bioabsorbable material such as polylactic acid (PLA) and polysulfone.
- PVA polylactic acid
- the suture anchor 12 should have a length sufficient to enable it to properly seat within bone.
- the anchor 12 is about 5 to 15 mm long, with the first, leading end 22 having at its narrowest portion a diameter of about 1 to 3 mm, a middle portion having a diameter of about 2 to 4 mm, and a second, trailing end having at its widest portion a diameter of about 2.5 to 5 mm.
- the anchor 12 is about 9 mm long with a leading end diameter of about 2 mm, an intermediate diameter of about 3 mm, and a diameter at the widest portion of the trailing end of about 4 mm.
- the suture thread-engaging groove 23 can have a depth of about 1 to 2.5 mm and an inner diameter of about 0.5 to 1 mm.
- the first suture loop 14 may be suitably attached to the suture anchor 12 through a hole or holes provided in the body of the suture anchor 12 or by a suture retaining slot formed within the body of the suture anchor 12 .
- the first suture loop 14 is attached at a location substantially intermediate the first 22 and second ends 24 of the suture anchor 12 , and portions of first suture loop 14 extend past the second end 24 on opposed sides 26 , 28 of the suture anchor 12 .
- the first suture loop 14 may be attached to the suture anchor 12 as illustrated in FIG. 3.
- the first suture loop 14 is formed from a length of suture thread by tying the two free ends of the thread into a knot 30 . It will be understood that other methods of attaching the two free ends, including the use of suture loop closure devices as further described below with regard to the second suture loop, may be used.
- the suture anchor 12 includes a through-hole 32 intermediate the first 22 and second ends 24 .
- the through-hole 32 is adapted, by providing varying diameters within the through-hole 32 , to retain the first suture loop 14 .
- the diameter within the through-hole 32 is varied by providing an annular collar 34 therein.
- the inner diameter of the annular collar 34 is large enough to allow the unknotted portion of the first suture loop 14 to pass therethrough.
- the inner diameter of the annular collar 34 is small enough, however, to prevent the knot 30 from passing through the through-hole 32 .
- the second end 24 of the suture anchor 12 may be provided with a mating feature for mating the suture anchor 12 to the anchor insertion tool 20 .
- anchor insertion tool 20 has a threaded insertion tip 36 that engages a threaded bore 38 formed in the second end 24 of the suture anchor 12 .
- Other configurations may be used as required.
- the first suture loop 14 may be constructed from thread suitable for use as a suture.
- a variety of suture materials are well known to those of ordinary skill in the art. Exemplary materials include braided polyester and polydioxanone (PDS).
- the length of the first suture loop 14 may be determined by a person of ordinary skill in the art depending upon the specific application desired for the system. This dimension depends, to a large extent, upon the dimensions of the tissue to be attached, the type of surgery to be performed, and whether an open or closed surgical technique is to be used.
- the length of the first suture loop may range from about one quarter to one and one half inches in procedures to repair a Bankart lesion or a rotator cuff tear. In an exemplary embodiment as used in the method described hereinbelow, the length of the first suture loop 14 is about 0.25 to 2 inches.
- the suture needle 16 has a first, tissue penetrating end 40 and a second trailing end 42 .
- the size and shape of the needle used with the system of the invention may be selected by a person of ordinary skill in the art depending upon the specific application of the system, and in particular, depending upon whether the system is used in an open or closed (e.g., arthroscopic) surgical procedure.
- needle 16 is at least slightly curved.
- the second suture loop 18 is attached to the suture needle 16 at the second end 42 of needle 16 .
- the second end 42 of the suture needle 16 can be hollowed so that two free ends of suture thread may be inserted therein. The hollowed end is then crimped to securely retain the two ends of suture thread within the second end 42 of the needle 16 , thus creating the second suture loop 18 .
- the second suture loop 18 may be attached to the needle 16 a by means of a suture loop closure 44 .
- the second suture loop 18 may be formed by securing two free ends of a length of suture thread within a suture loop closure 44 .
- the suture loop closure 44 may consist of a metal tube having an internal diameter large enough to admit two ends of suture thread. The two free ends of the suture thread are then entered into the suture loop closure 44 and the suture loop closure 44 is crimped to retain the ends of the suture thread and form the second suture loop 18 .
- the suture loop closure 40 may take other forms, including a knot tied with the two free ends of the suture thread.
- a second suture loop 18 having a suture loop closure 44 , may be attached to a suture needle 16 a as shown in FIG. 5.
- the suture needle 16 a is a hollow member, having an open distal end 40 , one wall of which includes a tissue-penetrating edge or point 41 .
- a slot 46 is formed in the wall of the distal end of the needle, preferably opposite point 41 .
- the slot 46 has an open end 43 that communicates with the open distal end 40 of the suture needle 16 a and an opposite, closed end 45 .
- the slot 46 is wide enough to slidably engage the second suture loop 18 , but narrow enough to retain the suture loop closure 44 on one side of the slot 46 .
- the second suture loop 18 is then attached to the suture needle 16 a by placing the suture loop closure 44 inside the open first end 40 of the hollow suture needle 16 a and sliding the suture loop closure 44 and the attached second suture loop 18 within the slot 46 to the closed end thereof.
- the hollow suture needle 16 a of FIG. 5 may also include an internally disposed actuator 48 .
- the actuator 48 may be a rod that is selectively slidable within the hollow suture needle 16 a between a first position, in which the actuator 48 is inside the hollow needle 16 a and does not reach the slot 46 , and a second position (not shown), in which the actuator 48 extends past the slot 46 . Selectively sliding the actuator 48 from the first position to the second position causes the actuator 48 to contact the suture loop closure 44 (and the attached second suture loop 18 ), causing closure 44 to slide the length of slot 46 and become disengaged from the needle 16 .
- Suture needle 16 a is well suited for use in closed surgical procedures.
- the suture needle 16 a may form the distal end of an elongate suture inserter tool (e.g., an arthroscopic, laparoscopic or endoscopic tool) that is useful in closed surgical procedures.
- the second suture loop 18 like the first suture loop 14 , may be constructed from well known materials suitable for use as a suture. The length of the second suture loop may be determined by a person of ordinary skill in the art depending upon factors such as the dimensions of the tissue to be attached, the type of surgery to be performed, and whether an open or closed surgical technique is to be used.
- the length of second loop 18 is generally in the range of about 20 to 40 inches, and more preferably about 30 to 36 inches for closed surgical procedures.
- Open surgical procedures can utilize a smaller length for second loop 18 , in the range of about 6 to 40 inches and more preferably 8 to 10 inches.
- FIG. 2 illustrates an exemplary insertion tool 20 , the distal end 50 of which includes an insertion tip 36 that is threadably mated with the second end 24 of the suture anchor 12 .
- the suture anchor 12 may be removably premated to the distal end of the insertion tool.
- FIGS. 6 - 13 depict the method in the context of arthroscopic shoulder repair, more specifically, attaching a detached labrum (as might result from a Bankart lesion or rotator cuff tear) to the glenoid rim of a scapula. It will be understood, however, that the system and method described herein are equally applicable to connecting detached tissue in other contexts as well.
- a bore 52 is formed in a bone 54 .
- the diameter of the bore 52 should be slightly smaller than the widest portion of the second, trailing end 24 of the suture anchor 12 .
- the diameter of the bore 52 is approximately 3 mm when the widest part of the suture anchor is about 4 mm.

Abstract
A suture anchor system includes a suture anchor, a first loop of suture thread attached to the suture anchor, a suture needle, and a second loop of suture thread which is attached to the suture needle. The first and second suture loops are interlocked with one another. The suture anchor is preferably bioabsorbable, and it has a flared feature on one side of the second or proximal end thereof. The flared feature renders the suture anchor asymmetrical in a plane that includes the longitudinal axis of the anchor. A method for anchoring soft tissue is also disclosed.
Description
- This application is a continuation of application Ser. No. 09/691,498, filed Oct. 18, 2000, titled “Knotless Suture Anchor System And Method Of Use,” which is hereby incorporated by reference in its entirety.
- Not Applicable.
- The invention relates to a knotless suture anchor system for attaching soft tissue to hard bone, and to methods for attaching soft tissue to hard bone.
- Soft tissues, such as ligaments, tendons and muscles, are attached to a large portion of the human skeleton. In particular, many ligaments and tendons are attached to the bones which form joints, such as shoulder and knee joints. A variety of injuries and conditions require attachment or reattachment of a soft tissue to bone. For example, when otherwise healthy tissue has been torn away from a bone, surgery is often required to reattach the tissue to the bone to allow healing and a natural reattachment to occur.
- A number of devices and methods have been developed to attach soft tissue to bone. These include screws, staples, cement, suture anchors, and sutures alone. Some of the more successful methods involve use of a suture anchor to attach a suture to the bone, and tying the suture in a manner that holds the tissue in close proximity to the bone.
- The tissue may be attached to the bone during open surgery, or during closed (e.g., arthroscopic) surgical procedures. Closed surgical procedures are preferred since they are less invasive and are less likely to cause patient trauma. In a closed surgical procedure, the surgeon performs diagnostic and therapeutic procedures at the surgical site through small incisions, called portals, using instruments specially designed for this purpose. One problem encountered in the less invasive, closed surgical procedures is that the surgeon has significantly less room to perform the required manipulations at the surgical site. Thus, devices and methods are needed which will allow a surgeon to effectively and easily attach tissue to bone in the small spaces provided by less invasive surgical procedures.
- Conventional methods for attaching soft tissue to bone typically require that the surgeon tie a knot in the suture thread to attach the suture to an anchor, or to attach the tissue to the bone using the suture. Knot tying at the surgical site in closed surgical procedures, and even in open surgery, is difficult and time consuming due to inherent space constraints. Further, knots and other bulky attachment means can irritate tissue over time.
- Knotless suture anchor systems have been developed for use with closed surgical procedures, and U.S. Pat. No. 5,569,306 provides one example of such a system. A further knotless suture anchor and system is disclosed in U.S. Pat. No. 5,782,864. Although generally useful, such systems can be limited to use only with certain types or shapes of tissue, or to use with certain anatomical structures. Proper attachment of soft tissue requires that it be placed in the anatomically correct position to promote optimal healing.
- Further, some conventional knotless suture anchor systems may require, in order to attach a broader array of tissue shapes to bone, that the suture anchor pass though the tissue to be attached. This is undesirable because it unnecessarily irritates the injured tissue and it requires opening a much larger hole in the tissue.
- There is thus a need for an improved system for anchoring soft tissue to bone which reduces or eliminates the need to tie suture knots at the surgical site. Further, there is a need for an improved system for anchoring soft tissue to hard bone which is easy and fast to deploy and requires few tools. It would also be advantageous to provide a fully absorbable knotless suture anchor and system.
- The present invention provides a system for anchoring tissue to bone including a suture anchor, a first suture loop attached to the suture anchor, a suture needle and a second suture loop attached to the suture needle and interlocked with the first suture loop. The second suture loop may be formed by attaching two free ends of a length of suture thread directly to the suture needle, or by attaching the two free ends within a suture closure which may then be attached to the suture needle. In a preferred embodiment, the suture anchor is entirely bioabsorbable. A method is also provided by which a detached tissue may be securely attached to bone in an anatomically correct position without the need to tie a knot.
- In an exemplary embodiment, the system includes a suture anchor having a first, leading end, a second, trailing end, and two opposed sides between the first and second ends. The second end has a flared portion that renders the suture anchor asymmetrical in a plane that includes the longitudinal axis. The first suture loop is attached at a position between the first and second ends of the suture anchor and is interlocked with the second suture loop. The second suture loop is attached to a trailing end of the suture needle. The asymmetrical shape of the suture anchor assists in securing the anchor within bone. When tension and deflection by the inserter is applied to the suture anchor, after the anchor is positioned within bone, the anchor undergoes a toggling action, or rotation which results in the anchor being oriented in a direction that is not parallel with the longitudinal axis of the anchor-seating bore. This toggling of the anchor causes the anchor to become lodged within the bone. Thus, the anchor can be firmly embedded within bone without the need for ancillary anchoring structure such as arcs.
- In an embodiment that is particularly useful in closed surgery, the second suture loop is formed using a suture loop closure and is attached to a hollow suture needle by means of a slot provided in a wall of the hollow needle. This embodiment may also employ an actuator, disposed within the hollow needle, which can be selectively deployed to disengage the second suture loop from the needle. The hollow needle used with this embodiment preferably is part of an elongate tool, such as a suture inserter, that is useful in closed surgical procedures. The hollow needle typically forms the distal end of such a tool.
- The system may be used in a method wherein the suture needle and the attached second suture loop are passed through a detached segment of tissue. The second suture loop is pulled through the detached tissue until a portion of the interlocked first suture portion of the first suture loop is seated within a suture thread-engaging groove at the first end of the anchor. The anchor is then tapped into a predrilled bore in a portion of hard bone. Once inside the bone, tension is applied to the anchor by sutures, causing the anchor to toggle such that it is no longer oriented in a direction parallel to the longitudinal axis of the bore, and the flared portion of the anchor engages and is wedged into the wall of the bore. The suture anchor is thus stabilized in an interference fit within the bore, and the detached tissue is thereby attached to the bone in the desired position.
- The term “suture needle” is used herein to encompass both conventional suture needles, used in open surgical procedures, as well as suture needles that may form a hollow, distal end of an elongate tool useful with closed surgical procedures.

- Referring to FIG. 1, a
system 10 for anchoring tissue to bone in accordance with the invention is shown. The system includes asuture anchor 12, afirst suture loop 14 attached to thesuture anchor 12, asuture needle 16 and asecond suture loop 18 attached to thesuture needle 16. Thefirst suture loop 14 and thesecond suture loop 18 are interlocked with each other. The system may also include ananchor inserter tool 20. - The
suture anchor 12 has a first, leadingend 22 and a second, trailingend 24. The first, leadingend 22 tapers, while the second trailingend 24 flares out at one side, rendering the suture anchor asymmetrical in a plane that includes the longitudinal axis 11. In the exemplary embodiment shown in FIG. 1, thesuture anchor 12 has two flat,opposed sides sides sides adjacent sides - The
exemplary suture anchor 12 additionally comprises a suture thread-engaginggroove 23 at thefirst end 22 for seating portions of the first loop ofsuture thread 14. The second, trailingend 24 includes a flaredportion 25, which is integral withside 17. As shown in FIG. 1, flaredportion 25 is located between the two opposedflat sides portion 25 may include a sharp edge for penetrating into hard bone, such as cortical bone. Flaredportion 25 may also include a knife-like edge (not shown) with a rounded proximal end to promote bone penetration. Additionally,suture anchor 12 may include surface features (not shown) to promote secure seating within bone and to prevent theanchor 12 from backing out of the bone once inserted. - As noted, the flared
portion 25 preferably is formed only on one side of thesuture anchor 12. The flared portion results from a gradual widening of one side of the anchor. At its maximum dimension, the flared portion causes the suture anchor to be about 0.5 to 1.5 mm, preferably 1.0 mm, wider than it would be without the flared portion. As shown in FIG. 1, the flaredportion 25 has a breadth dimension (B) that is consistent with the breadth ofside 17, with which it is integral. The breadth (B) of the flaredportion 25 is preferably about 0.3 to 1 mm. - The
suture anchor 12 may be constructed from suitable metals or polymers known to those of ordinary skill in the art. In a preferred embodiment,suture anchor 12 is fully bioabsorbable and is constructed from a bioabsorbable material such as polylactic acid (PLA) and polysulfone. Thesuture anchor 12 should have a length sufficient to enable it to properly seat within bone. In an exemplary embodiment, theanchor 12 is about 5 to 15 mm long, with the first, leadingend 22 having at its narrowest portion a diameter of about 1 to 3 mm, a middle portion having a diameter of about 2 to 4 mm, and a second, trailing end having at its widest portion a diameter of about 2.5 to 5 mm. In one embodiment, theanchor 12 is about 9 mm long with a leading end diameter of about 2 mm, an intermediate diameter of about 3 mm, and a diameter at the widest portion of the trailing end of about 4 mm. The suture thread-engaginggroove 23 can have a depth of about 1 to 2.5 mm and an inner diameter of about 0.5 to 1 mm. - The
first suture loop 14 may be suitably attached to thesuture anchor 12 through a hole or holes provided in the body of thesuture anchor 12 or by a suture retaining slot formed within the body of thesuture anchor 12. In theexemplary suture anchor 12, thefirst suture loop 14 is attached at a location substantially intermediate the first 22 and second ends 24 of thesuture anchor 12, and portions offirst suture loop 14 extend past thesecond end 24 onopposed sides suture anchor 12. - In an additional embodiment, the
first suture loop 14 may be attached to thesuture anchor 12 as illustrated in FIG. 3. Thefirst suture loop 14 is formed from a length of suture thread by tying the two free ends of the thread into aknot 30. It will be understood that other methods of attaching the two free ends, including the use of suture loop closure devices as further described below with regard to the second suture loop, may be used. - As shown in FIGS. 2 and 3, the
suture anchor 12 includes a through-hole 32 intermediate the first 22 and second ends 24. The through-hole 32 is adapted, by providing varying diameters within the through-hole 32, to retain thefirst suture loop 14. In an exemplary embodiment, the diameter within the through-hole 32 is varied by providing anannular collar 34 therein. The inner diameter of theannular collar 34 is large enough to allow the unknotted portion of thefirst suture loop 14 to pass therethrough. The inner diameter of theannular collar 34 is small enough, however, to prevent theknot 30 from passing through the through-hole 32. When the unknotted portion of thefirst suture loop 14 is drawn through the through-hole 32, as illustrated in FIG. 3, theknot 30 is retained by theannular collar 34 and thefirst suture loop 14 is thereby attached to thesuture anchor 12. - As can further be seen by reference to FIG. 2, the
second end 24 of thesuture anchor 12 may be provided with a mating feature for mating thesuture anchor 12 to theanchor insertion tool 20. As illustrated,anchor insertion tool 20 has a threadedinsertion tip 36 that engages a threadedbore 38 formed in thesecond end 24 of thesuture anchor 12. Other configurations may be used as required. - The
first suture loop 14 may be constructed from thread suitable for use as a suture. A variety of suture materials are well known to those of ordinary skill in the art. Exemplary materials include braided polyester and polydioxanone (PDS). - The length of the
first suture loop 14 may be determined by a person of ordinary skill in the art depending upon the specific application desired for the system. This dimension depends, to a large extent, upon the dimensions of the tissue to be attached, the type of surgery to be performed, and whether an open or closed surgical technique is to be used. By way of example, the length of the first suture loop may range from about one quarter to one and one half inches in procedures to repair a Bankart lesion or a rotator cuff tear. In an exemplary embodiment as used in the method described hereinbelow, the length of thefirst suture loop 14 is about 0.25 to 2 inches. Referring again to FIG. 1, thesuture needle 16 has a first,tissue penetrating end 40 and a second trailingend 42. The size and shape of the needle used with the system of the invention may be selected by a person of ordinary skill in the art depending upon the specific application of the system, and in particular, depending upon whether the system is used in an open or closed (e.g., arthroscopic) surgical procedure. Generally,needle 16 is at least slightly curved. - In the exemplary embodiment of FIG. 1, which is typically used in open surgical procedures, the
second suture loop 18 is attached to thesuture needle 16 at thesecond end 42 ofneedle 16. One of ordinary skill in the art will appreciate that a number of techniques can be utilized to join thesecond suture loop 18 to thesuture needle 16. For example, thesecond end 42 of thesuture needle 16 can be hollowed so that two free ends of suture thread may be inserted therein. The hollowed end is then crimped to securely retain the two ends of suture thread within thesecond end 42 of theneedle 16, thus creating thesecond suture loop 18. - In an alternative embodiment, shown in FIGS. 4 and 5, that is particularly suited for use in closed surgical procedures the
second suture loop 18 may be attached to theneedle 16 a by means of asuture loop closure 44. Referring now to FIG. 4, thesecond suture loop 18 may be formed by securing two free ends of a length of suture thread within asuture loop closure 44. Thesuture loop closure 44 may consist of a metal tube having an internal diameter large enough to admit two ends of suture thread. The two free ends of the suture thread are then entered into thesuture loop closure 44 and thesuture loop closure 44 is crimped to retain the ends of the suture thread and form thesecond suture loop 18. It will be understood that thesuture loop closure 40 may take other forms, including a knot tied with the two free ends of the suture thread. Asecond suture loop 18, having asuture loop closure 44, may be attached to asuture needle 16 a as shown in FIG. 5. In this exemplary embodiment, thesuture needle 16 a is a hollow member, having an opendistal end 40, one wall of which includes a tissue-penetrating edge orpoint 41. Aslot 46 is formed in the wall of the distal end of the needle, preferably oppositepoint 41. Theslot 46 has anopen end 43 that communicates with the opendistal end 40 of thesuture needle 16 a and an opposite,closed end 45. Theslot 46 is wide enough to slidably engage thesecond suture loop 18, but narrow enough to retain thesuture loop closure 44 on one side of theslot 46. Thesecond suture loop 18 is then attached to thesuture needle 16 a by placing thesuture loop closure 44 inside the openfirst end 40 of thehollow suture needle 16 a and sliding thesuture loop closure 44 and the attachedsecond suture loop 18 within theslot 46 to the closed end thereof. - The
hollow suture needle 16 a of FIG. 5 may also include an internally disposedactuator 48. Theactuator 48 may be a rod that is selectively slidable within thehollow suture needle 16 a between a first position, in which theactuator 48 is inside thehollow needle 16 a and does not reach theslot 46, and a second position (not shown), in which theactuator 48 extends past theslot 46. Selectively sliding the actuator 48 from the first position to the second position causes theactuator 48 to contact the suture loop closure 44 (and the attached second suture loop 18), causingclosure 44 to slide the length ofslot 46 and become disengaged from theneedle 16. -
Suture needle 16 a, as noted above, is well suited for use in closed surgical procedures. Thesuture needle 16 a may form the distal end of an elongate suture inserter tool (e.g., an arthroscopic, laparoscopic or endoscopic tool) that is useful in closed surgical procedures. Thesecond suture loop 18, like thefirst suture loop 14, may be constructed from well known materials suitable for use as a suture. The length of the second suture loop may be determined by a person of ordinary skill in the art depending upon factors such as the dimensions of the tissue to be attached, the type of surgery to be performed, and whether an open or closed surgical technique is to be used. For example, the length ofsecond loop 18 is generally in the range of about 20 to 40 inches, and more preferably about 30 to 36 inches for closed surgical procedures. Open surgical procedures can utilize a smaller length forsecond loop 18, in the range of about 6 to 40 inches and more preferably 8 to 10 inches. - It is understood that various anchor insertion tools may be used with the system of the present invention. FIG. 2 illustrates an
exemplary insertion tool 20, thedistal end 50 of which includes aninsertion tip 36 that is threadably mated with thesecond end 24 of thesuture anchor 12. In some embodiments, thesuture anchor 12 may be removably premated to the distal end of the insertion tool. - The system of the invention for anchoring tissue to bone may be used in the method described herein below. For purposes of illustration, FIGS.6-13 depict the method in the context of arthroscopic shoulder repair, more specifically, attaching a detached labrum (as might result from a Bankart lesion or rotator cuff tear) to the glenoid rim of a scapula. It will be understood, however, that the system and method described herein are equally applicable to connecting detached tissue in other contexts as well.
- Referring to FIG. 6, a
bore 52 is formed in abone 54. The diameter of thebore 52 should be slightly smaller than the widest portion of the second, trailingend 24 of thesuture anchor 12. In an exemplary embodiment, the diameter of thebore 52 is approximately 3 mm when the widest part of the suture anchor is about 4 mm. The length of the bore must be of sufficient length to allow for complete seating of the anchor, and to enable the depth of the anchor to be adjusted to help control the tightness of thefirst suture loop 14. The actual length of thebore 52 will depend upon the length of thefirst suture loop 14 and the thickness of thedetached tissue 56. - As shown in FIG. 7, the
suture needle 16 is then passed through thedetached tissue 56. Thesuture needle 16 and the attachedsecond suture loop 18 are pulled through thedetached tissue 56 to advance the interlockedfirst loop 14 through the tissue, as illustrated in FIG. 8. If the procedure is being performed arthroscopically, thesuture needle 16 a and the tool with which it is associated will be pulled from, and exit through, an exit portal (not shown). - Alternatively, in embodiments that utilize the
needle 16 a, shown in FIG. 5, theneedle 16 a may penetrate thedetached tissue 56. Theactuator 48 is then selectively moved so as to disengage thesuture loop closure 44 and the attachedsecond suture loop 18 from theneedle 16 a. Thesuture needle 16 a may then be withdrawn from the patient's body from the portal through which the needle entered. A suture grasper or retrograder (not shown) may be used to pull the remaining portion of thesecond loop 18 through thedetached tissue 56. - In FIG. 9, the
first suture loop 14 is positioned over thebore 52 by manipulating the position of thesecond suture loop 18. When thefirst suture loop 14 is in its desired position, theinsertion tool 20 is maneuvered so that a portion of thefirst suture loop 14 is seated in the suture thread-engaginggroove 23 ofsuture anchor 12, as shown in FIG. 10. Once thefirst suture loop 14 is seated, theanchor 10 is aligned with thebore 52. By applying force to theinsertion tool 20, thesuture anchor 12 is forcibly urged into thebore 52.Suture anchor 12 can be tapped into thebore 52, or it can be positioned in another manner. In the case of polymeric suture anchors 12, because the diameter of thebore 52 is slightly smaller than the widest part of thesuture anchor 12, some of the polymeric material forming thesuture anchor 12 may be scraped off during the insertion step to allow thesuture anchor 12 to pass through the opening of thebore 52. When thesuture anchor 12 is partially inserted, as illustrated in FIG. 11, thesecond suture loop 18 can be cut and discarded along with thesuture needle 16. - Referring to FIG. 12, when the
suture anchor 12 is advanced into thebore 52, there will be a tight interference fit between thebore 52 and theanchor 12. By compressing and manipulating theanchor 12 using theinsertion tool 20, the surgeon can wedge the flaredportion 25 of theanchor 12 into the bone tissue within thebore 52. Further, when tension is applied to theanchor 12, the asymmetrical shape will cause a toggling of the anchor, resulting in theanchor 12 becoming lodged within thebone 54. As shown in FIG. 12,insertion tool 20 can include a flexible neck, orportion 21 that allows the tool to bend when pressure is exerted. This enables a compressive force to be greater on one side of the anchor, resulting in toggling or rotating the anchor. FIG. 13 shows thesuture anchor 12 wedged inside thebore 52, resulting in a snug, anatomically correct attachment of thedetached tissue 56 to thebone 54. Once theanchor 10 is inserted intobore 52, theinsertion tool 20 may be removed. - It will be understood that the foregoing is only illustrative of the principles of the invention, and that various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention. All references cited herein are expressly incorporated by reference in their entirety.
