Abstract:
The present invention is referred to a tissue approximating device comprising a two-piece anastomosis clamp that can be used to approximate two tissue sections together via open or laparoscopic technique, via Natural Orifice Translumenal Endoscopic Surgery (NOTES) or via single site surgery. The clamp includes a first member and a second member, where the clamp members are operable configured to fasten together, in juxtaposition to establish an anastomosis. The first clamp member includes a set of spikes and with a circumferential indentation and the second clamp member includes also a set of complementary receptacles for receiving said spikes and a circumferential indentation too. Said members have a circular shape, and they are made out of an absorbable material. The purposed method includes the steps of:a) Cutting the bowel for removing a portion thereof, thus defining two loose ends of bowel tissue;
b) Inserting into one loose end of bowel tissue a first annular bio-absorbable clamp member, including a set of spikes on the front face,
c) Inserting into the second loose end of bowel a second annular clamp member including a stent-like tube integral therewith and set of complementary receptacles aligned with said spikes and on its front face;
d) Anchoring said first clamp members to the bowel's tissue;
e) Introducing said first clamp member around said stent-like tube also made of bio-absorbable material;
f) Approximating both clamp members by moving said first clamp member towards said second clamp member around the stent-like tube until the first annular member remains in front of the second annular clamp member;
g) Inserting said spikes into said receptacles, and
h) Approximating the end edges of said loose ends of the bowel if necessary.
