First Claim
1. A guard for use in combination with an anastomotic surgical stapling apparatus, wherein the surgical stapling apparatus is configured and adapted to dispense staples from a staple pusher member of a body portion of the surgical stapling apparatus and to deliver wound treatment material from a stem of an anvil assembly of the surgical stapling apparatus to a target surgical site, wherein the guard comprises:
- a central hub defining a lumen therethrough for receiving the stem of the anvil assembly of the surgical stapling apparatus;
an annular cuff supported by the central hub and extending at least substantially therearound, wherein the annular cuff is configured to be disposed radially outward of a staple line of the surgical stapling apparatus, and wherein the annular cuff defines an arcuate upper lip connected to an arcuate lower lip; and
