VACUUM MEMBRANE THERMOFORMED POLY-4-HYDROXYBUTYRATE MEDICAL IMPLANTS
20220096705 · 2022-03-31 · ·

Methods to produce thermoformed implants comprising poly-4-hydroxybutyrate homopolymer, copolymer, or blend thereof, including surgical meshes, have been developed. These thermoforms are preferably produced from porous substrates of poly-4-hydroxybutyrate homopolymer or copolymer thereof, such as surgical meshes, by vacuum membrane thermoforming. The porous thermoformed implant is formed by placing a porous substrate of poly-4-hydroxybutyrate homopolymer or copolymer thereof over a mold, covering the substrate and mold with a membrane, applying a vacuum to the membrane so that the membrane and substrate are drawn down on the mold and tension is applied to the substrate, and heating the substrate while it is under tension to form the thermoform. The method is particularly useful in forming medical implants of poly-4-hydroxybutyrate and copolymers thereof, including hernia meshes, mastopexy devices, breast reconstruction devices, and implants for plastic surgery, without exposing the resorbable implants to water and without shrinking the porous substrate during molding.
