Abstract
Implantable materials for use with end effectors like surgical stapling devices, and methods associated with the operation of such end effectors, are provided herein. In one exemplary embodiment, a staple cartridge assembly includes a cartridge body and a hybrid adjunct material. The cartridge body has a plurality of staple cavities configured to seat staples therein. The hybrid adjunct material is releasably retained on the cartridge body and configured to be delivered to tissue by deployment of the staples in the cartridge body. The material includes a biologic tissue membrane, a synthetic substrate layer, and at least one compressible elastic member configured to compress when a compressive force is applied thereto, and to provide a spring back force when the compressive force is removed. Other implants, devices, and methods for surgical stapling are also provided.
