Abstract
A surgical stapling apparatus includes a tool assembly, at least one surgical buttress, and a resilient, porous material. The tool assembly includes a cartridge assembly and an anvil assembly pivotably coupled to the cartridge assembly. The cartridge assembly includes a first tissue facing surface defining staple retaining slots. The anvil assembly includes a second tissue facing surface defining staple pockets for forming staples expelled from the staple retaining slots of the cartridge assembly. The at least one surgical buttress is releasably disposed on at least one of the first and second tissue facing surfaces. The resilient, porous material is releasably disposable between the first and second tissue facing surfaces and in contact with the at least one surgical buttress. The resilient, porous material is configured to expel a liquid therefrom upon compression thereof by an approximation of the cartridge assembly and the anvil assembly.
