Patent CA-2059458-A1 (CA)
Inventor: BRINKERHOFF RONALD J
IPC: A61B17/115
Filed: 1992-01-16
Abstract: ABSTRACT          A mechanism which is capable of anastomosis of two lumens by an absorbable fastener.  The fastener is made from two washer-like plates.  One such plate has holes to receive latching prongs protruding from the other plate. Fastening is done through a single linear motion that causes the prongs to pierce the tissue, latches the prongs into a receiver and causes a knife blade to cut through excess fastener material and tissue.  The ease of removal, by pulling the mechanism thorugh the formed anastomosis, is greatly enhanced.  The system can be used such that the plates can be placed in any configuration to properly anastomose tissue.
