First Claim
Patent Images
1. A surgical stapling apparatus, comprising:
- a jaw assembly including a pair of jaw members; and
a surgical buttress positioned adjacent a tissue contacting surface of at least one of the pair of jaw members, the surgical buttress comprising a plurality of microbeads each having a polymeric casing defining a core containing a hemostatic agent therewithin, at least a portion of the plurality of microbeads being configured to rupture and release the hemostatic agent therefrom upon actuation of the surgical stapling apparatus to approximate the pair of jaw members and exert a pressure on the surgical buttress, the microbeads having a predetermined rupturing force.

13. A surgical stapling apparatus, comprising:
-
a jaw assembly including a staple forming anvil jaw member and a staple cartridge jaw member; a trigger for actuating the jaw assembly between an open position where the anvil jaw member and the staple cartridge jaw member are spaced apart from one another and a closed position where the anvil jaw member and the staple cartridge jaw member are substantially adjacent to one another and for applying at least one row of staples to tissue when the jaw assembly is in the closed position; and a surgical buttress positioned adjacent a tissue contacting surface of at least one of the anvil jaw assembly or the staple cartridge jaw assembly, the surgical buttress containing a plurality of microbeads each having a bioabsorbable polymeric casing defining a core containing a hemostatic agent therewithin, at least a portion of the plurality of microbeads being configured to rupture and release the hemostatic agent subsequent to actuation of the trigger and approximation of the jaw assembly to the closed position, and the polymeric casing of a remaining portion of the microbeads being configured to degrade and release the hemostatic agent over time, the polymeric casing having a predetermined rupturing force. - View Dependent Claims (14, 15, 16, 17)

18. A staple cartridge, comprising:
-
a staple cartridge containing a plurality of staples for use in a surgical stapling apparatus; and a surgical buttress disposed on a tissue contacting surface of the staple cartridge and being releasably affixed to the staple cartridge, the surgical buttress comprising a layer of polymeric material including a plurality of microbeads each having a polymeric casing defining a core containing a hemostatic agent therewithin, at least a portion of the plurality of beads being configured to rupture and release the hemostatic agent therefrom upon application of pressure thereto, the microbeads having a predetermined rupturing force. - View Dependent Claims (19, 20, 21)
