<p num="1"><br/><br/>An annular gasket for use with a circular stapling apparatus in performing an <br/>anastomosis is disclosed. The annular gasket comprises a substantially <br/>circular body <br/>portion having an upper surface, a lower surface, an outer terminal edge, and <br/>an inner <br/>terminal edge defining an aperture therein. The body portion defines a central<br/><br/>longitudinal axis through the aperture. The annular gasket also comprises a <br/>plurality of <br/>pores extending through the body portion. Each of the pores is disposed <br/>between the <br/>outer terminal edge and the inner terminal edge and extends from the upper <br/>surface to the <br/>lower surface such that each pore defines an axis that is substantially <br/>parallel to the <br/>central longitudinal axis. An outer region of the gasket is disposed radially <br/>outward of <br/>the plurality of pores and the outer region is substantially non-porous.<br/><br/>
