Publication number: 20240032922Abstract: A staple cartridge assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a first fibrous, woven material and a second fibrous, woven material. The first fibrous, woven material comprises a density which is different than the density of the second fibrous, woven material. The tissue thickness compensator is configured to expand upon contact with a fluid in order to apply a compressive force to tissue captured within staples.Type: ApplicationFiled: October 3, 2023Publication date: February 1, 2024Inventors: Chester O.

Patent number: 11857187Abstract: A tissue thickness compensator may generally comprise a first layer comprising a first biocompatible material sealingly enclosed in a water impermeable material and a second layer comprising a second biocompatible material comprising at least one encapsulation, wherein the first biocompatible material expands when contacted with a fluid. The tissue thickness compensator may comprise a haemostatic agent, an anti-inflammatory agent, an antibiotic agent, anti-microbial agent, an anti-adhesion agent, an anti-coagulant agent, a medicament, and/or pharmaceutically active agent. The encapsulation may comprise a biodegradable material to degrade in vivo and/or in situ. The tissue thickness compensator may comprise a hydrogel. The reaction product may comprise a fluid-swellable composition. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.Type: GrantFiled: March 10, 2021Date of Patent: January 2, 2024Assignee: Cilag GmbH InternationalInventors: Chester O.
