Laparoscopic absorbable anastomosic fastener and means for applying
First Claim
1. In combination:
- an anastomotic coupler mechanism having a hollow tubular interior andan applier comprising a tubular shaft with proximal and distal ends and defining an axis for placement within said hollow interior;
a retaining mechanism at said distal end having a first position for holding said shaft within said hollow tubular interior; and
an activating mechanism located at said shaft proximal end, capable of activating said retaining mechanism to cause said retaining mechanism to move from its first position to a second position wherein said coupler may be released from said shaft; and
wherein said activating mechanism is a push button means which is connected to said retaining mechanism, and said push button means capable of causing said retaining mechanism to move from said first position transverse to said shaft to said second position.

Abstract
A mechanism and applier therefor which is capable of inverted anastomosis of two lumens by an absorbable fastener. The fastener is made from two washer-like plate assemblies and a pair of introducers. Each such plate assembly has slots to receive latching prongs protruding from the other plate, and pins to impale tissue. Fastening is done through an applier that causes the pins to pierce the tissue, and causes a knife blade to cut through excess tissue. Fastening is done by attaching fastener halves. Insertion and removal of the fastener and applier optimally is done in an endoscopic procedure through a trocar or through the surgical incision in an open procedure. The system can be used such that the plates can be placed to properly set gaps between and anastomose tissue. The introducer portion will soften intraluminally and be expelled, in about 24 hours. The coupler portion will remain in place for 2-3 weeks, typically, and then fragment and be expelled with the feces.
