SURGICAL STAPLER BUTTRESS ASSEMBLY WITH HUMIDITY TOLERANT ADHESIVE |
| 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. |

1. A buttress assembly that is configured to temporarily adhere to a wet surgical stapler end effector, the buttress assembly comprising:
(a) a buttress body; and (b) a humidity tolerant adhesive applied to at least one side of the buttress body, the humidity tolerant adhesive comprising a bioabsorbable polymer having a block configuration selected from the group consisting of:
(i) A-B-A, and(ii) A-B-C,wherein 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.;wherein 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%, and a molecular weight of from about 20 to about 80 kDa; andwherein the C block is a bioabsorbable hydrophilic homopolymer or co-polymer that is miscible with water at 37° C. |
