Abstract

ABSTRACT
ANASTOMOTIC COUPLING DEVICE
A three-piece anastomotic coupling device for end-to-end anastomosis of tubular members consisting of two open bore cylindrical adaptors and an open bore cylindrical connector. Each end of a tubular member is passed through the axial bore of an adaptor and everted over the end thereof. The adaptors are then inserted into opposite ends of the connector until the everted ends of the vessel abut under light compression. Integral locking means are pro-vided to secure the adaptors and tubular members of the connector piece.

Description

ETH-~7 ANASTOMOTIC COUPLING DEVICE

BACXGROUND OF THE INVENTION
The present invention relates to devices for end-to-end anastomosis of tubular organs, and more particularly, to anastomotic coupling devices for reconnecting the ends of severed blood vessels in a manner to promote the healing thereof.
End-to-end anastomosis of sevexed vessels may be accomplished either by suturing, stapling or mechanical coupling. Suturing is generally-difficult to perform, especially when very small vessels are involved, and re-quires great skill and experience on the part o the surgeon.
Suturing is also susceptible to complications resulting from damage to the vascular wall, leakage, and potential harboring of infection around the suture material.
Stapling and mechanical coupling of bloGd vessels has been suggested to avoid the disadvantages of 5Ut uring, and to provide a faster, more reliable and relatively sim-ple mothod of anastomosis. Various designs for mechanical couplins devices have been proposed, as for example, in U.S. Patents Nos. 2,453,056; 3,221,746; 3,254,650; 3,774,515;
and 3,974,835.
The ideal anastomotic coupling device should pro~
vide perfect adap~ation of the vascular members without damage to tne vascula~ wall, and be completely external of the vascular lumen. In addi~ion, the device must provide for auick, sure placement with a minimal posslbility for error on the part o the su-geon.
It is accordingly an object of th present inven-tion to provide an anastomotic coupling device providing ~..
: , , . -, , .
2--the afore6aid characteristics. It is a further o~ject of this invention to provide an anastomotic ccupling device particularly adapted for joining small blood vessels. A
yet further object of this invention is to provide a de-vice for joining the ends of interrupted tubular organs ofvarious sizes and functions, including, for example, veins, arteries, lymphatic ducts, oviducts, ureters, intestin2s~
and the like. These and other objects of the present in-vention will be evident from the ensuing description and claims.

SUMMARY
~ he anastomotic coupling device of the present in-vention consists of three pieces: two tubular adaptors and one intexlocking connector piece. Preferred adaptors con-si3t of an open cylindrical section terminating at one end in an expanding truncated conical section. The exterior surface of the conical section is provided with means for interlocking with said connector piece as hereinafter de-scribed.
The connector piece preferably consists of an open cylinder terminating at each end in extensions having meaTls thereon for interlocking with said adaptors when said adaptors are inserted into said conn2ctor.
In application, one end of the tubular member to be joined i~ passed through the conical sec.ion and cylin~
drical saction of one adap.or and everted over the end of the cylindrical section. The exterior surface of the cy-lindrical section is preferably provided with means for gripping the everted end of the tubular member.
The second adaptor is secured to the end of the other tubular member in a like manner.
One adaptox with the tubular member everted thereon is inserted into one end of the connector and Ihe locking means on the conical sec ion of said adaptor inter--locked with the locking means on the extensions of said connector. The se~-ond adaptor with the tubul2r member everted thereon is inserted into the other end of the - ~3~5~

connector and interlocked therewith in a like manner to com-plete the connection of the tubular member.
The inside diameter of the cylindrical section of the connector is greater than the outside diameter of the cylindrical section of the adaptor by an amount sufficient to accommodate the wall thickness of the everted tubular member. Preferably, the diameters are sized so that a small compressive force is exerted on the wall of the tubular mem-ber in the assembled connector.
The length of the cylindrical section of each adaptor is sized so that when assembled in the connector, the ends of the adaptors are spaced apart by a distance slightly less than twice the wall thickness of the tubular member. In this manner, the intimal surfaces of the everted ends of the tubular member are brought into contact under light compression which is effective to prevent leakage and is desirable to promote healing of the joined tissue.
The coupling device is completely external to the lumen of the tubular organ, and intraIuminal juncture be-tween the two ends is smooth and uniform. The flow ofblood or other fluid through the tubular organ is thereby maintained without disruption or stagnation which could re-sult in thrombosis or promote infec~ion.
In accordance with a particular embodiment of the invention, a three piece anastomotic coupling device for end-to-end anastomosis of tubular members comprises two adaptors and a connector, each of said adaptors comprising a cylinder having an axial bore therethrough sized to receive one tubular member with the end of said member everted over the end of said adaptor, said connector comprising a cylinder having an axial bore therethrough sized to receive each of said adaptors and the tubular member everted thereover in opposing ends of said cylinder with the everted ends of the tubular members in abutting contact within said cylinder, and means for inter-locking said adaptors and said connector to maintain the evertedends of the tubular mem~ers in contact.

. ~

~S~i6 - 3a -In accordance with a further embodiment of the invention, a three-piece anastomotic coupling device for joining the severed ends of a tubular member comprises ~wo adaptors and an interlocking connector, each of said adaptors comprising a cylinder having an axial bore therethrough terminating at one end in a plane normal to the axis of the bore and at the other end in an e~panding truncated conical member, means on the exterior s~rface of said conical member for interlocking with corresponding means on said connector piece, and means on the exterior surface of the plane end of said cylinder for gripping a tubular member everted thereover, said connector comprising a cylinder having an axial bore therethrough, and terminating at each end in appenda~es extending therefrom and having means on the interior surfaces at the distal ends thereof for interlocking with corresponding means on said adaptors, the inside diameter of the cylinder of said connector being larger than the maximum outside diameter of the cylinder of the adaptor, and the length of each adaptor being such that the ends of the adaptors are spaced apart when interlocked with said connector in the assembled coupling device, whereby each end of the tubular member to be joined may be passed through the conical member and cylinder of each adaptor and everted over the end thereo~, and said ends of said adaptors and everted tubular members thereon may be inserted into opposite ends o~
said connector and interlocked therewith with the intimal sur-faces of the everted tubular members abutting one another.

DESCRlPTTON OF PREFERRED EMBODIMENTS
Referrlng now to Figure 1, there is il1ustrated in partial cross section adaptor 10 cons sting of cylindrica section 11 and expanding truncated conical section 12. A
plurality of annular ridges 13 circumscribe the outer circum-ference of section 11 over an area extending from the open end thereof. A single annular recess 14 circumscribes coni-cal section 12 and forms lockins ridge 15, the surface of which is in a plane substantially vertical to the axis of the adaptor.
Figure 2 illustrates in cross section a connector indicated generally as 16 for use with the adaptor o~
Figure 1. Connector 16 consists of a central cylindrical section 17 having locking appendages 18 and guiding append-ages 19 extendins from either end thereof. As illusLrated,locking appendages 18 are located on the vertical axis of the connector, and each appendage has distal locking means consisting of a beveled surface 20 forming ridge 21 on the inner surface thereof, the surface of ridge 21 being in a plane substantially vertical to the axis of the connector.
Also, as illustrated in Figure 2, guiding append-ages 19 are located on the horizontal axis of the connector.
Appendages 19 serve as guides during the assembly of the coupling and are not provided with locking means as best ~5 sean in the cross-sectional view of Figure 3.
Referring urther to Figure 2 and Figure 3, ap-pendages 18 and 19 are ~eveled at 22 in order ~o increase the effective inside diameter of the partial cylinder de-fined by the appendages and thereby facilitate and guide the insertion of the adaptors into the connector.
Referring now to Figure 4, there is illustrated a fully assembled coupling device according to Figures 1 and 2 with the tubular member omitted for clarity. Adaptors 10 are inserted into connector 16 until locking appendages 18 engage annular recess 14 in the adaptor, at which ~ime ridge 21 of appendage 18 abuts ridge 15 of the adaptor locking the adaptor securely in place. Bevel 20 on append~
age 18 guides the distal end of the appendage over the conical se_tion ~f the adaptor and into annlllar recess 1~.

S~

Guide appendages 19 (not shown in Figure 4), in cooperation with lock~ng appendages 18, assure positive positioning of the adaptor in the connector, and the dual locking appendages on opposing sides of the adaptor secure the adaptor firmly in position.
In the assembled coupling there is provided a de-sign space 23 between the outside diameter of the cylindri-cal section of the adaptor and the inside diameter of the cylindrical section of the connector. Space 23 serves to accommodate the wall o the tubular member which is everted over the end of the adaptor before assembly of the coupling.
Preferably, the width of space 23 is slightly less than the wall thickness in order to apply a light compressive force on the everted wall of the tubular member.
The assembled coupling also provides design space 24 between opposing ends of the adaptors in order to accom-modate the double wall thic~ness of the everted ends of the tubular mambers. The width of space 24 is preferably slightly less than twice the wall thic~ness in order to apply a compressive force on the everted walls o the tubu-lar members sufficient to prevent leakage through the junc-tion. A light compressive force also assures a smooth, con-tinuous, intraluminal junction between the everted ends of the tubular members and minimize any disruption of laminar flow within the lumen of the vessel.
The assembly of an adaptor to a severed end of a tubular member is illustrated in Figure 5 where vessel 25 is passed through the cylindrical bore of adaptor 10 and end 26 of vessel 25 is everted over the cylindrical section of the adaptor. Preferably, the everted portion of the vessel extends at least half way over the cylindrical sec-tion of the adaptor and sufficiently over gripping means 13 on the external surface of the adaptor to secure the adaptor on the vessel.
A fully assembled anastomotic coupling device joining the severed ends of a tubular member is illustrated in Figure 6.
The adaptor OL Figure 1 may be simplified by omit~
ting all or a major portion of the conical section as ~3~

illustrated in Figure 7. This design simplifies abrication of the piece and reduces the mass of foreign material to be implanted in the body which may be desirable under certain circumstances. The simplified design has a disadvantage, however, in being more difficult to handle and to assemble in the coupling device.
The anastomotic coupling device of the present invention may be construct~d in a variety of sizes, and is especially useful in connecting very small vessels, i.e., 1 ~o 5 mm OD, which are particularly difficult to suture.
The adaptors of the coupling device should have an inside diameter approximately equal to the outside diameter of the vessel for best results.
The coupling device may also be fabricated in larger sizes corresponding to the ou~side diameters of large veins, arteries, and intestines, and may furthermore be used to join natural tubular members to synthetic de-vices such as vascular prostheses of Dacron~or Teflon~
The coupling devices may be fabricated by any convenient means such às machining or molding, and of a variety of materials which are known to be biocompatible in surgical applications. Nyl~n, polypropylene, and poly-sulfone are illustrative of polymeric materials which are readily shaped into the miniature pieces of the coupling device. The device may also be fabricated of stainless steel, or of biologically absorbable materials such as polylactide, polyglycolide, and copolvmers of lactide alld glycolide which are known to hydrolyze in tissue with eventual complete absorption by the body.
The preceding description has been largely di-rected to preferred embodiments of the present invention, and many variations thereof will be apparent to those skilled in the art. For example, one or more locking ap-pendages 18 may be substituted for each guiding appendage 19 illustrated in Figure 4, and various means for inter-locking the end pieces and the connec~or piece may ba em-ployed withou~ departing from the spirit or scope o the present invention. In additlon, vessel gripping means 13 illustrated in Figure 1 may be omit.ed, or other gripping ~3~

means such as a knurled surface or miniature spikes may be substituted for the annular rings of the illustration.
The essential element of the present invention is a three-piece coupling device for end-to-end anastomosis of tubular members comprising two adaptors, each sized to receive the severed end of a tubular member with the end of the member everted over the adaptor, and a cylindrical con-nector sized to receive and secure each adaptor individually with the everted ends of the tubular member in abutment within said connector.
