Definitions
- Stents, grafts, stent-grafts, vena cava filters and similar implantable medical devices, collectively referred to hereinafter as stents, are radially expandable endoprostheses which are typically intravascular implants capable of being implanted transluminally and enlarged radially after being introduced percutaneously.
- Stents may be implanted in a variety of body lumens or vessels such as within the vascular system, urinary tracts, bile ducts, etc. Stents may be used to reinforce body vessels and to prevent restenosis following angioplasty in the vascular system. They may be self-expanding or expanded by an internal radial force, such as when mounted on a balloon.
- Stents are generally tubular devices for insertion into body lumens.
- Balloon expandable stents require mounting over a balloon, positioning, and inflation of the balloon to expand the stent radially outward.
- Self-expanding stents expand into place when unconstrained, without requiring assistance from a balloon.
- a self-expanding stent is biased so as to expand upon release from the delivery catheter.
- Some stents may be characterized as hybrid stents which have some characteristics of both self-expandable and balloon expandable stents.
- Stents may be constructed from a variety of materials such as stainless steel, Elgiloy, nitinol, shape memory polymers, etc. Stents may also be formed in a variety of manners as well. For example a stent may be formed by etching or cutting the stent pattern from a tube or section of stent material; a sheet of stent material may be cut or etched according to a desired stent pattern whereupon the sheet may be rolled or otherwise formed into the desired tubular or bifurcated tubular shape of the stent; one or more wires or ribbons of stent material may be braided or otherwise formed into a desired shape and pattern.
- a stent may be formed by etching or cutting the stent pattern from a tube or section of stent material; a sheet of stent material may be cut or etched according to a desired stent pattern whereupon the sheet may be rolled or otherwise formed into the desired tubular or bifurcated tubular shape of the
- a vessel having a stenosis may be viewed as an inwardly protruding arcuate addition of hardened material to a cylindrical vessel wall, where the stenosed region presents a somewhat rigid body attached along, and to, the elastic wall.
- the stenosis presents resistance to any expansion of the vessel in the region bridged by the stenosis.
- Stenoses vary in composition, for example, in the degree of calcification, and therefore vary in properties as well.
- a stent may be used to provide a prosthetic intraluminal wall e.g. in the case of a stenosis to provide an unobstructed conduit for blood in the area of the stenosis.
- An endoluminal prosthesis comprises a stent which carries a prosthetic graft layer of fabric and is used. e.g. to treat an aneurysm by removing the pressure on a weakened part of an artery so as to reduce the risk of embolism, or of the natural artery wall bursting.
- a stent or endoluminal prosthesis is implanted in a blood vessel at the site of a stenosis or aneurysm by so-called “minimally invasive techniques” in which the stent is compressed radially inwards and is delivered by a catheter to the site where it is required through the patient's skin or by a “cut down” technique in which the blood vessel concerned is exposed by minor surgical means.
- minimally invasive techniques in which the stent is compressed radially inwards and is delivered by a catheter to the site where it is required through the patient's skin or by a “cut down” technique in which the blood vessel concerned is exposed by minor surgical means.
- U.S. Pat. No. 4,886,062 discloses a vascular stent which comprises a length of sinuous or “zig-zag” wire formed into a helix; the helix defines a generally cylindrical wall which, in use, constitutes a prosthetic intraluminal wall.
- the sinuous configuration of the wire permits radial expansion and compression of the stent;
- U.S. Pat. No. 4,886,062 discloses that the stent can be delivered percutaneously and expanded in situ using a balloon catheter.
- U.S. Pat. No. 4,733,665 discloses an expandable intraluminal graft which is constituted by a tubular member formed from a plurality of intersecting elongate members which permit radial expansion and compression of the stent.
- EP-A-0556850 discloses an intraluminal stent which is constituted by a sinuous wire formed into a helix; juxtaposed apices of the wire are secured to one another so that each hoop of the helix is supported by its neighboring hoops to increase the overall strength of the stent and to minimize the risk of plaque herniation; in some embodiments the stent of EP-A-0556850 further comprises a tubular graft member to form an endoluminal prosthesis.
- the devices cited above are generally satisfactory for the treatment of aneurysms, stenoses and other angeological diseases at sites in continuous unbifurcated portions of arteries or veins.
- a bifurcation is an area of the vasculature or other portion of the body where a first (or parent) vessel is bifurcated into two or more branch vessels.
- the lesion(s) can affect only one of the vessels (i.e., either of the branch vessels or the parent vessel) two of the vessels, or all three vessels.
- a vessel bifurcation is the left and right common carotid arteries. These arteries are the principal arteries of the head and neck. Both of the common carotid arteries are quite similar and divide at a carotid bifurcation or bulb into an external carotid artery and an internal carotid artery. In the region of the carotid bulb and the ostium of the internal carotid artery, stenoses present a particular problem for carotid stenting due to the large tapering of the vessel interior from the common carotid artery (both the left and the right) to the internal carotid artery. The region of the carotid bifurcation or bulb happens to be where stenoses most often occur, particularly in the region of the ostium to the internal carotid artery in both of the carotid arteries.
- Embodiments of the present invention relate to endoluminal prosthesis (stents) that may be utilized in the region of a bifurcation of vessels.
- the present invention also embraces stent connecting means for connecting a stent (e.g. a stent which forms part of an endoluminal prosthesis or bifurcated stent) to another stent or portion thereof.
- a stent e.g. a stent which forms part of an endoluminal prosthesis or bifurcated stent

- Stents, grafts, stent-grafts, vena cava filters and similar implantable medical devices, collectively referred to hereinafter as stents, are radially expandable endoprostheses which are typically intravascular implants capable of being implanted transluminally and enlarged radially after being introduced percutaneously. Stents may be implanted in a variety of body lumens or vessels such as within the vascular system, urinary tracts, bile ducts, etc. Stents may be used to reinforce body vessels and to prevent restenosis following angioplasty in the vascular system. They may be self-expanding or expanded by an internal radial force, such as when mounted on a balloon.
- Stents are generally tubular devices for insertion into body lumens. Balloon expandable stents require mounting over a balloon, positioning, and inflation of the balloon to expand the stent radially outward. Self-expanding stents expand into place when unconstrained, without requiring assistance from a balloon. A self-expanding stent is biased so as to expand upon release from the delivery catheter. Some stents may be characterized as hybrid stents which have some characteristics of both self-expandable and balloon expandable stents.
- Stents may be constructed from a variety of materials such as stainless steel, Elgiloy, nitinol, shape memory polymers, etc. Stents may also be formed in a variety of manners as well. For example a stent may be formed by etching or cutting the stent pattern from a tube or section of stent material; a sheet of stent material may be cut or etched according to a desired stent pattern whereupon the sheet may be rolled or otherwise formed into the desired tubular or bifurcated tubular shape of the stent; one or more wires or ribbons of stent material may be braided or otherwise formed into a desired shape and pattern.
- A vessel having a stenosis may be viewed as an inwardly protruding arcuate addition of hardened material to a cylindrical vessel wall, where the stenosed region presents a somewhat rigid body attached along, and to, the elastic wall. The stenosis presents resistance to any expansion of the vessel in the region bridged by the stenosis. Stenoses vary in composition, for example, in the degree of calcification, and therefore vary in properties as well.
- A stent may be used to provide a prosthetic intraluminal wall e.g. in the case of a stenosis to provide an unobstructed conduit for blood in the area of the stenosis. An endoluminal prosthesis comprises a stent which carries a prosthetic graft layer of fabric and is used. e.g. to treat an aneurysm by removing the pressure on a weakened part of an artery so as to reduce the risk of embolism, or of the natural artery wall bursting. Typically, a stent or endoluminal prosthesis is implanted in a blood vessel at the site of a stenosis or aneurysm by so-called “minimally invasive techniques” in which the stent is compressed radially inwards and is delivered by a catheter to the site where it is required through the patient's skin or by a “cut down” technique in which the blood vessel concerned is exposed by minor surgical means. When the stent is positioned at the correct location, the catheter is withdrawn and the stent is caused or allowed to re-expand to a predetermined diameter in the vessel.
- U.S. Pat. No. 4,886,062 discloses a vascular stent which comprises a length of sinuous or “zig-zag” wire formed into a helix; the helix defines a generally cylindrical wall which, in use, constitutes a prosthetic intraluminal wall. The sinuous configuration of the wire permits radial expansion and compression of the stent; U.S. Pat. No. 4,886,062 discloses that the stent can be delivered percutaneously and expanded in situ using a balloon catheter.
- U.S. Pat. No. 4,733,665 discloses an expandable intraluminal graft which is constituted by a tubular member formed from a plurality of intersecting elongate members which permit radial expansion and compression of the stent.
- EP-A-0556850 discloses an intraluminal stent which is constituted by a sinuous wire formed into a helix; juxtaposed apices of the wire are secured to one another so that each hoop of the helix is supported by its neighboring hoops to increase the overall strength of the stent and to minimize the risk of plaque herniation; in some embodiments the stent of EP-A-0556850 further comprises a tubular graft member to form an endoluminal prosthesis.
- The devices cited above are generally satisfactory for the treatment of aneurysms, stenoses and other angeological diseases at sites in continuous unbifurcated portions of arteries or veins.
- Within the vasculature however it is not uncommon for stenoses to form at a vessel bifurcation. A bifurcation is an area of the vasculature or other portion of the body where a first (or parent) vessel is bifurcated into two or more branch vessels. Where a stenotic lesion or lesions form at such a bifurcation, the lesion(s) can affect only one of the vessels (i.e., either of the branch vessels or the parent vessel) two of the vessels, or all three vessels. Many prior art stents however are not wholly satisfactory for use where the site of desired application of the stent is juxtaposed or extends across a bifurcation in an artery or vein such, for example, as the bifurcation in the mammalian aortic artery into the common iliac arteries.
- In the case of an abdominal aortic aneurysm (“AAA”) in the infiarenal portion of the aorta which extends into one of the common iliac arteries, the use of one of the prior art prosthesis referred to above across the bifurcation into the one iliac artery will result in obstruction of the proximal end of the other common iliac artery; by-pass surgery is therefore required to connect the one iliac artery in juxtaposition with the distal end of the prosthesis to the other blocked iliac artery. It will be appreciated by a person skilled in the art that it is desirable to avoid surgery wherever possible; the requirement for by-pass surgery associated with the use of the prior art prosthesis in juxtaposition with a bifurcation in an artery therefore constitutes a significant disadvantage.
- Another example of a vessel bifurcation is the left and right common carotid arteries. These arteries are the principal arteries of the head and neck. Both of the common carotid arteries are quite similar and divide at a carotid bifurcation or bulb into an external carotid artery and an internal carotid artery. In the region of the carotid bulb and the ostium of the internal carotid artery, stenoses present a particular problem for carotid stenting due to the large tapering of the vessel interior from the common carotid artery (both the left and the right) to the internal carotid artery. The region of the carotid bifurcation or bulb happens to be where stenoses most often occur, particularly in the region of the ostium to the internal carotid artery in both of the carotid arteries.
- Embodiments of the present invention relate to endoluminal prosthesis (stents) that may be utilized in the region of a bifurcation of vessels. The present invention also embraces stent connecting means for connecting a stent (e.g. a stent which forms part of an endoluminal prosthesis or bifurcated stent) to another stent or portion thereof. Some embodiments of the invention are directed to designs of bifurcated stents and their method of manufacture, as well as apparatuses and methods for introducing prostheses to the vasculature and methods of treating angeological diseases.
- All US patents and applications and all other published documents mentioned anywhere in this application are incorporated herein by reference in their entirety.
- Without limiting the scope of the invention a brief summary of some of the claimed embodiments of the invention is set forth below. Additional details of the summarized embodiments of the invention and/or additional embodiments of the invention may be found in the Detailed Description of the Invention below.
- A brief abstract of the technical disclosure in the specification is provided as well only for the purposes of complying with 37 C.F.R. 1.72. The abstract is not intended to be used for interpreting the scope of the claims.
- The present invention includes many different embodiments. Various embodiments of the invention are directed to designs of bifurcated stents and/or the methods and apparatuses utilized to deliver a bifurcated stent to a bifurcation site.
- In at least one embodiment, the invention is directed to a bifurcated stent delivery system that includes a unique catheter assembly having a primary and secondary guide wire wherein the secondary guide wire diverges away from the primary guide wire through a split in the catheter housing. The split allows the catheter to deliver a bifurcated stent center first.
- The bifurcated stent is an embodiment of the invention that comprises a primary stent section and a secondary stent section. When used with the above catheter, the primary section is delivered center first through the split in the catheter housing. The secondary stent section is then delivered into a secondary vessel according to the predelivery placement of the secondary guide wire.
- The bifurcated stent may be a one piece design where the primary and secondary sections are engaged to one another prior to delivery or it may be a two-piece design where the primary and secondary sections are separate and distinct stent bodies that may be optionally engaged to one another during delivery. The primary and secondary stent sections are preferably self-expandable but may be either self-expandable or balloon expandable independent of one another.
- In another embodiment of the invention a self-expandable bifurcated stent may be delivered by a catheter having a retractable outer sheath or sleeve that retains the bifurcated stent in a collapsed state. When the sheath is retracted the primary stent section is exposed to self-expand. In at least one embodiment the secondary stent section remains in the collapsed state within the expanded primary stent section until a pusher mechanism is actuated to cause the secondary stent section to self-expand.
- In at least one embodiment of the invention, a catheter system is employed wherein two guide wires and at least two balloons are employed to deliver a single piece bifurcated stent. In at least one embodiment, the balloons are substantially parallel to one another and the bifurcated stent is placed over both balloons with a single balloon extending into each section of the bifurcated stent. As a result, the stent branches may be independently guided and expanded. Where a portion of the stent is disposed about both balloons, in some embodiments the balloons may be linked together with a restrictive collar or band of material that will limit the expandability of the balloons to prevent the stent from being over expanded, however in other embodiments the collar may be omitted.
- In some embodiments of the invention the catheter may also employ two angioplasty balloons that are initially advanced to the bifurcation site prior to stent delivery.
- In at least one embodiment of the invention the bifurcated stent to be delivered is a one piece bifurcation stent comprising a primary stent section and a secondary stent section, the secondary stent section is linked to the primary stent section with one or more flexible linkage members. In at least one embodiment at least four linkage members connect the stent sections. Preferably, the flexible members are substantially S-shaped and/or are selectively annealed.
- In at least one embodiment, the invention is directed to a single piece bifurcated stent wherein the primary stent section and the secondary stent section are engaged together by a linkage which allows the bifurcated stent to form distinct support structures on either side of the carina of a bifurcation. Preferably, the linkage comprises at least one struts or connecting members that is shared by both stent sections. In at least one embodiment the linkage is constructed from a selectively annealed metal or other material.
- In the various embodiments of the invention portions of a given catheter and/or stent may include radiopaque materials to aid in visual inspection and/or placement of the devices such as during fluoroscopy.
- Additional details and/or embodiments of the invention are discussed below.

- In
FIG. 1 an embodiment of the invention is shown which comprises a bifurcated stent delivery system shown generally at 100.System 100 includes acatheter 10 that is advanced to abifurcation site 20 along aprimary guide wire 12 and asecondary guide wire 14. In use, theprimary guide wire 12 andsecondary guide wire 14 are advanced into a body lumen or vessel an advanced into theprimary vessel 22. At thebifurcation site 20 thesecondary guide wire 14 is directed into asecondary vessel 24 causing theguide wires carina 26.Catheter 10 is advanced along the shared path of theguide wires carina 26. - In order to accommodate the divergent path of the
secondary guide wire 14, thecatheter 10 includes a spiltarea 30 where thesecondary guide wire 14 exits thecatheter 10. The spiltarea 30 is a gap between two portions of theouter housing 32 of thecatheter 10. Thehousing 32 may be characterized as a sheath, sleeve, sock or any other assembly suitable for retaining a stent in its collapsed state onto a stent receiving region of a catheter. Some examples of such stent retaining devices are described in U.S. Pat. No. 4,950,227 to Savin et al.; U.S. Pat. No. 5,403,341 to Solar; U.S. Pat. No. 5,108,416 to Ryan et al.; U.S. Pat. No. 5,968,069 to Dusbabek et al.; U.S. Pat. No. 6,068,634, to Cornelius et al.; U.S. Pat. No. 5,571,168; U.S. Pat. No. 5,733,267; U.S. Pat. No. 5,772,669; and U.S. Pat. No. 5,534,007 all of which are incorporated herein by reference in their entirety. - In the embodiment shown in
FIG. 1 , thehousing 32 comprises adistal sleeve 34 and aproximal sleeve 36. As is more clearly shown inFIG. 2 ,sleeves stent retaining region 38 of thecatheter 10.Sleeves - In
FIG. 1 thesleeves bifurcated stent 50, shown inFIG. 2 , which is disposed about astent retaining region 38.Stent retaining region 38 may include a balloon or other inflatable area for use in expanding and/orseating stent 50.Stent 50 may be balloon expandable, self-expanding or a hybrid type stent. - In the embodiments shown in
FIGS. 2-4 thebifurcated stent 50 comprises aprimary stent section 52 and asecondary stent section 54. Preferably, bothsections sections bifurcated stent 50 may be individual stent bodies that are separately advanced and deployed formingstent 50 once they are fully deployed, or they may be integrally formed or otherwise connected prior to their deployment. - In the embodiment shown in
FIG. 2 , the housing portions orsleeves bifurcated stent 50. As thesleeves primary stent section 52 will begin to radially expand in a center first manner through thesplit area 30. When thesleeves FIG. 3 theprimary stent section 52 is completely freed from thestent retaining region 38. - If the
stent section primary section 52 the secondary section may be advanced along thesecondary guide wire 14 and advanced to anopening 62 in thewall 64 of theprimary stent section 52.Opening 62 may be any diameter or shape but preferably is sized to accommodate the outer diameter of thesecondary stent section 54 as well as the inner diameter of thesecondary vessel 24. - Whether the
secondary stent section 54 is engaged to theprimary stent section 52 or separate therefrom prior to deployment, when thesecondary stent section 54 is in position at opening 62 and theprimary section 52 has been expanded, thesecondary stent section 54 is then deployed into thesecondary vessel 24, such as is shown inFIG. 4 . The position of thestent 50 at the bifurcation site maybe visually established through the use of aradiopaque marker 90, discussed in greater detail below. - In at least one embodiment, where the
secondary stent section 54 is at least partially constructed from a shape memory material, such as nitinol, thesecondary stent section 54 will self expand according to a preprogrammed shape memory, such that the section both radially and longitudinally expands into thesecondary vessel 24. In some embodiments,catheter 10 may include apusher assembly 70 that is advanced along thesecondary guide wire 14 to trigger expansion of thesecondary stent section 54.Pusher assembly 70 may provide a stimulus which causes thesection 54 to expand. Such a stimulus may be in the form of a simple mechanical engagement; delivery of an electrical current; or delivery of a predetermined temperature and/or a predetermined pH, such as by the release of a heated saline bolus. In some embodiments, a separate balloon catheter or other inflation device may be advanced along thesecondary guide wire 14 to fully expand and/or seat thesecondary stent section 54. - When both
stent sections FIG. 5 , the proximal end of thesecondary stent section 54 is preferably engaged to thewall 64 of theprimary stent section 52. When fully deployed theprimary stent section 52 defines aprimary flow path 72 and the secondary stent section defines asecondary flow path 74 that is in fluid communication with the primary flow path viaopening 62. - In an alternative embodiment of the invention, such as is shown in
FIG. 6 ,system 100 may be provided withcatheter 10 that is equipped with at least two balloons, aprimary balloon 80 and asecondary balloon 82, which may be utilized for expansion and/orseating stent sections - In the embodiment shown in
FIG. 6 thebifurcated stent 50 may be constructed from stainless steel or other material that necessitates or would benefit from balloon expansion. As with previous embodiments, thecatheter 10 includes a pair ofguide wires bifurcation site 20 and which diverge at thecarina 26 with thesecondary guide wire 14 advancing into thesecondary vessel 24. - In the embodiment shown in
FIG. 6 , during most of the advancement of thecatheter 10 theballoons catheter 10 approaches thebifurcation site 20 thedistal portion 86 ofsecondary balloon 82 andsecondary stent section 54 are directed along thesecondary guide wire 14 into thesecondary vessel 24 as shown inFIG. 9 . - In order to ensure that the bifurcated stent will provide adequate support to the
vessels carina 26, thecatheter 10 may include aradiopaque marker 90.Marker 90 allows a practitioner to advance thecatheter 10 to thebifurcation site 20 and visually determine through fluoroscopy or other means that theballoons stent sections carina 26. -
Marker 90 may be constructed from any radiopaque material and is preferably part of thebifurcated stent 50. - Once it is determined that the
stent 50 is in proper position at thebifurcation site 20, theprimary balloon 80 is inflated to expand theprimary stent section 52 as shown inFIG. 10 . After the initial expansion of theprimary stent section 52, thesecondary balloon 82 is inflated to initially expand thesecondary stent 54 shown inFIG. 11 . - In some embodiments it may be preferable to first deflate the
primary balloon 80 before inflating thesecondary balloon 82. In some embodiments whereballoon 80 is deflated prior to inflation ofballoon 82,balloon 80 may be subsequently inflated after inflation ofballoon 82 to fully expand the stent and seat it in place within the bifurcation such as is shown inFIG. 12 . Alternatively, balloons 80 and 82 may be inflated simultaneously. - Once both
stent sections balloons bifurcation site 20, such as is depicted inFIG. 13 - Because some bifurcated stents may be subject to distortion or damage when over expanded or subjected to high radially outward acting pressure, in some embodiments, such as shown in
FIG. 7 , theproximal portion 88 ofballoons primary stent section 52, thecatheter 10 may employ acircumferential band 92 that will limit the expandability of theproximal portion 88 ofballoons primary stent portion 54 when both balloons are inflated.Band 92 may be constructed from any minimally or non-expandable material such as polyethyleneterephthalate (PET) or stainless steel. - In some applications, it may be beneficial or necessary to conduct an angioplasty procedure prior to insertion of the
bifurcated stent 50. As a result, in at least one embodiment of the invention, an example of which is shown inFIG. 8 , thecatheter 10 may be equipped with aprimary angioplasty balloon 94 and asecondary angioplasty balloon 96. Inpractice balloons bifurcation site 20 alongguide wires bifurcation site 20, theballoons blockage 98 that may be present. After theblockage 98 is reduced, theballoons guide wires respective vessels balloons bifurcation site 20 to delivery thebifurcated stent 50. - In the embodiments shown in
FIGS. 6-13 , thebifurcated stent 50 may be a single piece design, wheresections stent 50 may be a two-piece design where bothsections - In embodiments where the
stent 50 is a one-piece design, the stent sections may be engaged together by one ormore linkage member 102 such as are shown inFIGS. 14-16 . InFIGS. 14 and 15 thesections linkage members 102. In at least one embodiment, thesections linkage members 102.Linkage members 102 may be characterized as struts or connectingmembers 104 that are shared betweensections members 102 are selectively annealed to provide thebifurcated stent 50 with improved flexibility betweensections members 102, thesecondary stent section 52 may be articulated relative to theprimary stent section 54 such that thebifurcated stent sections reference numeral 106 inFIG. 15 , or a moreacute angle 108 shown inFIG. 14 . By providing abifurcated stent 50 that hassections sections - In at least one embodiment, the
linkage members 102 are provided with a curvilinear or S-shaped configuration such as is best shown inFIG. 15 . The S-shape of the linkage members aid in providing thebifurcated stent 50 with the ability to articulate about vessel junctions of various angles. - In at least one embodiment, shown in
FIG. 16 thesections bifurcated stent 50 are linked by asingle linkage member 102. When inserted at abifurcation site 20, the single linkage member is positioned at thecarina 26 and acts as a hinge to allow thesections carina 26. - In at least one embodiment of the invention shown in
FIG. 17 ,stent 50 includes aprimary stent section 52 which does not extend distally beyond thecarina 26. As a result thestent 50 may be advanced and positioned at thebifurcation site 20 by asinge guide wire 14 which extends into thesecondary branch 24. Use of amarker 90 allows a practitioner to position thestent 50 by abutting the marker adjacent to thecarina 26 and deploying the stent as shown. Thestent 50 may include sections that are either balloon expandable, self-expandable, or hybrid expandable as desired. In the embodiment shown,primary stent section 52 is balloon expandable, andsecondary stent section 54 is self-expandable. - In addition to being directed to the specific combinations of features claimed below, the invention is also directed to embodiments having other combinations of the dependent features claimed below and other combinations of the features described above.
