Woven and Fibrous Materials for Reinforcing a Staple Line

摘要

Adjunct materials and methods of using adjunct material to reinforce a staple line are provided. In general, an adjunct material can be used to maintain a seal in tissue and can prevent stapled tissue from tearing. In some embodiments, a surgical stapler can include a jaw having an adjunct material associated with the jaw. The adjunct material can be attached to tissue via staples deployed by the stapler. In some embodiments, an adjunct material can be a woven material having a single layer or multiple layers, and each layer can have different mechanical properties. In other embodiments, an adjunct material can have a single layer or multiple layers of nonwoven material, such as suture compressed into a three dimensional structure.

1. A staple cartridge for use with a surgical stapler, comprising:
a cartridge body having a plurality of staple cavities configured to seat staples therein; and, a biocompatible, compressible 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 material having a compressible elastic core layer configured to compress upon application of a compressive force and expand upon removal of the compressive force, and at least one flexible support layer coupled to at least a first surface of the compressible elastic core layer.
