Surgical Gasket
First Claim
1. A gasket for use with a surgical stapling apparatus, the gasket comprising:
- a body portion having an upper surface and a lower surface, the body portion defining a central longitudinal axis extending between the upper surface and the lower surface; and
a plurality of pores extending through the body portion, wherein each of the pores extends from the upper surface to the lower surface such that each pore defines an axis that is substantially parallel to the central longitudinal axis;
the body portion having an outer region disposed outwardly of the plurality of pores, wherein the outer region is substantially non-porous.

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