Abstract

An anastomosis fastening technique wherein an annular fastener securing anvil is positioned over the end portion of a first hollow body organ to be joined to a second hollow body organ end or side portion and this first organ end is everted outwardly back over the anvil thereby forming a cuff. The anvil is provided with prepositioned and annularly disposed fastener securing devices on the exterior surface. The second hollow body organ and/or side portion is then positioned over the cuff of the first hollow body organ such that the intimal portions thereof to be anastomosed are in intimal coaptation. An anastomotic surgical fastener driving instrument with fastener cartridges therein, and which conforms in shape to the outer annular contours of the anvil is coaxially applied over the anvil with the organ portions positioned therebetween and the fastener driving instrument is then actuated to fasten the coaptating organ portions together. The organ portions to be anastomosed may first be tied down to the anvil. The fastener driving instrument is also keyed to the anvil for proper positioning of the fasteners relative to the anvil fastener securing devices prior to actuating the fastener driving instrument. The fasteners may be in the form of surgical staples, nails or tacks.
