    Abstract: The present disclosure provides a compound three-dimensional surgical implant and methods of forming and using the same. The compound three-dimensional surgical implant includes a grip-type knit mesh defining pores and including a plurality of spiked naps extending from a surface the grip-type knit mesh, a prosthetic knit mesh defining principal cells and peripheral cells being layered on the grip-type knit mesh such that at least a portion of the spiked naps grip at least a portion of the cells of the prosthetic knit mesh. The grip-type knit mesh and the prosthetic knit mesh are folded together into a predetermined three-dimensional structure such that at least a portion of the spiked naps grip at least a portion of the pores of the grip-type knit mesh to hold the three-dimensional structure of the surgical implant.

    Abstract: A surgical stapling apparatus includes a handle assembly and an elongate portion extending distally from the handle assembly. An end effector disposed adjacent a distal portion of the elongate portion includes an anvil assembly and a cartridge assembly, wherein at least one of the cartridge assembly and the anvil assembly is movable with respect to the other to move the end effector between an open configuration where the cartridge assembly and the anvil assembly are substantially spaced and a closed configuration where the cartridge assembly and the anvil assembly are closer together. The end effector also includes a clamping assembly including a first clamping surface deployable to extend laterally from the anvil assembly, and a second clamping surface deployable to extend laterally from the cartridge assembly such that, when deployed, the first and second clamping surfaces oppose one another when the cartridge assembly is in the closed position.
