Abstract
A tissue retaining ring for use with a plurality of surgical fasteners mounted within a disposable loading unit utilized during a vascular anastomosis inlcudes a genrally circular, semi-pliable material having a series of alternating loops and arcuate portions. Each of the loops defines an aperture therein which is dimensioned to receive a distal end of one of the plurality of surgical fasteners. When the instrument is fired, the surgical fasteners are simultaneously deformed through the tissue ring and through the tissue. The tissue retaining ring holds the tissue in place along the surgical fastener and reduces the chances of tissue slippage after deformation.
