What changed

USPTO issued patent grant US12594361B2 to Tepha, Inc., establishing intellectual property protection for resorbable implants using poly(butylene succinate) and copolymers. The patent covers implants with less than 20 endotoxin units per device, oriented fibers, meshes, and 3D-printed forms suitable for procedures requiring prolonged strength retention. Additional coverage includes cardiac device receptacles containing antibiotics such as rifampin and minocycline.

Manufacturers developing resorbable surgical implants, hernia repair meshes, breast reconstruction devices, or cardiac device coverings should evaluate whether their technology falls within the scope of these 17 claims. Healthcare providers performing relevant procedures may benefit from understanding available licensed technologies in this space.

Abstract

Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.
