摘要： A staple cartridge is described. The staple cartridge includes a cartridge body, a plurality of staples, and an implantable layer. The implantable layer includes a piece of lyophilized foam and a plurality of fibers at least partially embedded in the piece of lyophilized foam. The implantable layer further includes a plurality of pores defined in piece of lyophilized foam, and a plurality of pockets, wherein a pocket at least partially surrounds a fiber. A method of forming an implantable layer for use with a surgical staple is also disclosed. The method comprises obtaining a mold comprising a cavity, placing a plurality of fibers in the cavity of the mold, dispensing a solution into the cavity around the fibers, and lyophilizing the solution in the cavity.

摘要： A staple cartridge is disclosed. The staple cartridge includes a cartridge body, a plurality of staples, and an implantable layer including a plurality of foam fragments, wherein the foam fragments are fused together to form a unitary body. The implantable layer further includes a plurality of intrastitial voids intermediate the foam fragments and/or a plurality of interstitial voids within the foam fragments. A method of forming an implantable layer for use with a surgical stapler is also disclosed. The method includes the steps of obtaining a plurality of foam fragments, heating the foam fragments, and compressing the foam fragments. The method of forming an implantable layer for use with a surgical stapler can also include lyophilizing a solution.
