Publication number: 20240066178Abstract: The invention relates to biodegradable bilayer sealants for tissue closure. The sealants of the invention are composed of two layers with different compliances. The layer in immediate contact with the tissue has high compliance. The second layer located immediately above the first sealant layer has low compliance, i.e. the sealant is much stiffer. The burst pressure of the bilayer sealants is enhanced relative to either a single layer elastic sealant or a single layer stiff sealant. The improved sealant compositions herein provide a water-tight seal, can access hard to reach tears, be applied in a dry or wet environment, are low-swelling, and can repair a range of incision or tear sizes. The bilayer sealants are particularly useful for sutureless dural closure or as adjuncts to sutured dural closure. Also provided herein are methods of preparing and using the biodegradable sealant compositions.Type: ApplicationFiled: August 30, 2022Publication date: February 29, 2024Applicant: Ethicon, Inc.Inventors: Salim A.
