First Claim
1. An anvil assembly for a circular stapling device, the anvil assembly comprising:
- an anvil head configured to support an anvil plate thereon;
a shaft extending from the anvil head and configured to selectively engage an actuator of the circular stapling device;
an anvil plate operatively connected to the anvil head and defining a tissue contacting surface, wherein the anvil plate defines a plurality of staple forming pockets in the tissue contacting surface at a location radially outward of the shaft and arranged in at least one annular array;
at least one recess formed in the anvil head, wherein the at least one recess extends away from a plane defined by the tissue contacting surface; and
a wound treatment material disposed substantially within the at least one recess.
