Abstract
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 provided to secure the adaptors and tubular members of the connector piece.
Claims20
A three-piece anastomotic coupling device for end-to-end anastomosis of tubular members comprising 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 interlocking said adaptors and said connector to maintain the everted ends of the tubular members in contact.
A three-piece anastomotic coupling device for joining the severed ends of a tubular member comprising two 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 expanding truncated conical member, means on the exterior surface 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 appendages extending thereform 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 thereof, and said ends of said adaptors and everted tubular members thereon may be inserted into opposite ends of said connector and interlocked therewith with the intimal surfaces of the everted tubular members abutting one another.
