Surgical stapling apparatus including releasable surgical buttress
First Claim
1. A staple cartridge assembly for use with a surgical stapling apparatus, the staple cartridge assembly comprising:
- a cartridge body including a proximal end, a distal end, a side surface extending from the distal end and towards the proximal end, and a tissue contacting surface at the distal end defining a plurality of staple retaining slots; and
a surgical buttress including a buttress body and a flange formed from a common material, the buttress body having an inner terminal radial edge defining an aperture and an outer terminal radial edge, the flange extending from at least one of the inner or outer terminal radial edges of the buttress body, the flange having a stiffened region having ruffles, wherein the stiffened region is formed by increasing rigidity of the flange such that a rigidity of the stiffened region is greater than a rigidity of the buttress body, and wherein the ruffles are secured to the side surface of the cartridge body for maintaining the buttress body of the surgical buttress on the tissue contacting surface of the cartridge body.

Abstract
A staple cartridge for use with a surgical stapling apparatus includes a cartridge body including a tissue contacting surface defining a plurality of staple retaining slots, a staple disposed within each staple retaining slot of the cartridge body, and a substantially circular buttress. The buttress includes an inner portion, an outer portion, and a middle portion extending between the inner portion and the outer portion. At least one stiffened region joins the buttress to the tissue contacting surface of the cartridge body. The inner portion, the middle portion, the outer portion, and the at least one stiffened region are all formed from a common material.

10. A surgical stapling apparatus, comprising:
-
a body portion having a distal end portion; an anvil assembly including an anvil plate and a shaft connectable with the distal end portion of the body portion; a staple cartridge assembly including a cartridge body receivable in the distal end portion of the body portion and having a tissue contacting surface; and a surgical buttress including a buttress body and a flange formed from a common material, the buttress body having an inner terminal radial edge defining an aperture and an outer terminal radial edge, the flange extending from at least one of the inner or outer terminal radial edges of the buttress body, the flange having a stiffened region having ruffles, wherein the stiffened region is formed by increasing rigidity of the flange such that a rigidity of the stiffened region is greater than a rigidity of the buttress body, and wherein the ruffles are secured to a side surface, extending in a direction towards the body portion, of the cartridge body for maintaining the buttress body of the surgical buttress on the tissue contacting surface of the cartridge body. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
