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&#xb0; C., a crystallinity as measured by X-ray diffraction of at least about 30%, and a melting temperature of at least about 50&#xb0; C. The B block is a bioabsorbable homopolymer or co-polymer that is characterized by a glass transition temperature of at least about &#x2212;40&#xb0; C., a crystallinity as measured by X-ray diffraction of at most about 25%, and 2 a molecular weight of from about 20 to about 80 kDa. The C block is a bioabsorbable hydrophilic homopolymer or co-polymer that is miscible with water at 37&#xb0; C.

Surgical stapler buttress assembly with humidity tolerant adhesive

A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.
