BIOLOGICALLY DERIVED EXTRACELLULAR MATRIX WITH INFUSED VISCOUS ABSORBABLE COPOLYMER FOR RELEASABLY ATTACHING A STAPLE BUTTRESS TO A SURGICAL STAPLER
摘要
A surgical stapler end effector comprises a staple cartridge, an anvil, and a buttress assembly. The staple cartridge comprises a plurality of staples and a deck. The staple cartridge is operable to drive the staples through the deck. The anvil is movable from an open position toward the staple cartridge to reach a closed position. The anvil includes an underside having staple forming surface configured to receive staples driven through the deck. The buttress assembly comprises a buttress body and an adhesive material. The buttress body defines a plurality of cells. The adhesive material comprises a polymer. The polymer is bioabsorbable. A first portion of the adhesive material is located within cells of the plurality of cells. A second portion of the adhesive material is located on the buttress body outside the plurality of cells.
