ADJUNCT MATERIAL TO PROMOTE TISSUE GROWTH IN A COLON

摘要

Adjunct material to promote tissue growth is provided. In general, an implantable adjunct can be configured to be applied to tissue by a surgical stapler in conjunction with staples. The adjunct 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. One or more characteristics associated with the adjunct can be altered between various implementations to promote organized tissue remodeling in a desired manner during wound healing, such as by encouraging tissue growth to be in a certain direction and/or by discouraging tissue growth in a certain area and/or on a certain structure.

主权项

1. A staple cartridge assembly for use with a circular surgical stapler, comprising:
a cartridge body having at least one annular row of staple cavities, each staple cavity having a surgical staple disposed therein; a biocompatible adjunct material releasably retained on the cartridge body and configured to be delivered to colon tissue in connection with deploying the staples from the cartridge body to form at least one line of deployed staples, the adjunct material being delivered along the at least one line of deployed staples, the adjunct material being in the form of a fiber lattice, the fiber lattice having at least two distinct heterogeneous fiber lattice sections, each of the fiber lattice sections of the adjunct material being arranged in a pattern configured to promote organized colon tissue remodeling in a desired manner; and an effective amount of at least one medicant disposed within and releasable from the adjunct material, each of the at least one medicants being effective to provide a desired effect on colon tissue in-growth in a predetermined manner, and each of the at least one medicants being releasable from the adjunct material in a homogeneous manner.
