摘要：
A buttress assembly is configured to temporarily adhere to a wet surgical stapler end effector. The buttress assembly includes a buttress body and a humidity tolerant adhesive. The adhesive includes a bioabsorbable polymer having a block configuration selected from the group consisting of A-B-A and A-B-C. The A block is a bioabsorbable homopolymer characterized by a glass transition temperature of at least about 0° C., a crystallinity as measured by X-ray diffraction of at least about 30%, and a melting temperature of at least about 50° C. The B block is a bioabsorbable homopolymer or co-polymer that is characterized by a glass transition temperature of at least about -40° C., a crystallinity as measured by X-ray diffraction of at most about 25%, and2 a molecular weight of from about 20 to about 80kDa. The C block is a bioabsorbable hydrophilic homopolymer or co-polymer that is miscible with water at 37° C.
