Adjunct Material to Provide Controlled Drug Elution

摘要

Adjunct material to provide controlled drug elution is provided. In general, an implantable adjunct formed from at least one bioabsorbable polymer can be configured to be applied to tissue by a surgical stapler in conjunction with staples. The adjunct can be made from a plurality of fibers and it can have one or more medicants releasably retained therein that are effective to provide a desired effect on tissue in-growth in a predetermined manner. Release of each of the at least one medicants from the adjunct material can be controlled by a degradation rate of the at least one bioabsorbable polymer.

主权项

1. A staple cartridge assembly for use with a surgical stapler, comprising:
a cartridge body having a plurality of staple cavities, each staple cavity having a surgical staple disposed therein; a bioabsorbable adjunct material releasably retained on the cartridge body and configured to be delivered to tissue by deployment of the staples in the cartridge body, the adjunct material being formed from at least one bioabsorbable polymer; and an effective amount of at least one medicant, the at least one medicant being releasably disposed in the adjunct material, each of the at least one medicant being effective to provide a desired effect on tissue in-growth in a predetermined manner, wherein release of each of the at least one medicant from the adjunct material is controlled by a degradation rate of the at least one bioabsorbable polymer.
