  • Patent number: 11589906
    Abstract: The invention relates to a biodegradable, magnesium-containing bone screw for implanting into a patient body for use in medical applications, such as, orthopedic, craniofacial and cardiovascular surgery. The bone screw has a head, shaft and tip. The thickness of the head is greater than the thickness of conventional bone screws. The shaft includes both a non-threaded and a threaded portion. The tip is non-threaded and pointed, such as, conical in shape. The composition of the bone screws provide for improved biodegradability and biocompatibility, and the features of the structure of the bone screws facilitate guidance and placement during implantation as well as reduce the potential for mechanical failures.

  • Publication number: 20210213170
    Abstract: Biomaterials disclosed herein can comprise a hydrogel comprising PEG, gelatin, and a glycosaminoglycan with sulfated moiety; and chondrogenic, osteogenic, and immunomodulatory cytokines; wherein the biomaterial is capable of potentiating bone regeneration in a compromised wound while reducing inflammatory response. The glycosaminoglycan with sulfated moiety can comprise heparin, heparan sulfate, keratin sulfate, chondroitin sulfate, dermatan sulfate, and/or similar materials. The biomaterial can further comprise mesenchymal stem cells (MSCs), a crosslinking initiator, microparticles and nanoparticles, and or other materials. The biomaterial can be injectable into a wound, or the biomaterial can be loaded in, or further comprise a porous scaffold providing mechanical support for other components of the biomaterial, such that it can be implanted into a wound.
