Abstract
The present invention provides an anchor system for musculoskeletal applications, e.g., for anchoring tendons or ligaments to bone or anchoring two or more bone sections. The anchor system comprises a substantially solid pre-manufactured distal portion (i.e., anchor component) and a settable, biodegradable composite. The biodegradable composite is flowable at the time of delivery and is introduced into the fixation site before or after the anchor component. Both the anchor component and the biodegradable composite may be manufactured from citrate-based polymers.
Claims18
A method of intracorporeally anchoring a device relative to bone, the method comprising:
- a. creating a bone cavity;
- b. introducing a flowable non-thermoplastic composite into the bone cavity, wherein the non-thermoplastic composite comprises a citrate-based polymer selected from the group consisting of poly(1,8-octanediol-citrate) (POC), methacrylated POC (mPOC), a crosslinked urethane-doped polyester (CUPE), biodegradable photoluminescent polymer (BPLP), dual-crosslinkable poly(alkylene maleate citrate) (PAMC) and a clickable POC-based elastomer (POC-Click);
- and
- c. pressing an anchor component into the bone cavity, wherein the anchor component comprises a citrate-based polymer selected from the group consisting of poly(1,8-octanediol-citrate) (POC), methacrylated POC (mPOC), a crosslinked urethane-doped polyester (CUPE), biodegradable photoluminescent polymer (BPLP), dual-crosslinkable poly(alkylene maleate citrate) (PAMC) and a clickable POC-based elastomer (POC-Click);
- wherein the anchor component forces the non-thermoplastic composite into interstices of the bone wherein the non-thermoplastic composite sets in situ.
