20210251762 · 2021-08-19 · ·

A bone implant includes at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak extending in a proximal direction or at least one valley extending in a distal direction. The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.

Orthognathic implant assembly and method of use

A maxillofacial orthognathic fixation implant assembly and its method of production and use, the implant being an assembly of an upper anchor implant member, a lower anchor implant member and at least one bridging implant member, the anchor implant members being adapted to be securely mounted to a maxilla and the at least one bridging implant member being adapted to connect the upper anchor implant member to the lower anchor implant member in a fixed and rigid manner. With the anchor implant members affixed to the maxilla and the maxilla surgically separated between the upper and lower anchor implant members to create a lower portion detached an upper portion, the at least one bridging implant member is connected between the upper and lower anchor implant members to secure and maintain the lower portion of the maxilla in a desired post-operative position relative to the upper portion of the maxilla.

ARTICLES OF POLY(BUTYLENE SUCCINATE) AND COPOLYMERS THEREOF

Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The 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 molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.
