  • Patent number: 9694037
    Abstract: Bioimplants and methods of making the bioimplants are provided. The bioimplants comprise biological tissues having conjugated thereto adjunct molecules. The biological tissues are sterilized with a chemical sterilizing agent, such as a water soluble carbodiimide. The processes of making the bioimplants include a process in which an adjunct molecule is conjugated to a biological tissue during the sterilization process.
    Type: Grant
    Filed: January 6, 2009
    Date of Patent: July 4, 2017
    Assignee: Synovis Orthopedic and Woundcare, Inc.

  • Patent number: 7153518
    Abstract: Disclosed herein are novel injectable, biocompatible compositions, preferably, comprising a combination of particulate, processed tissue and a carrier. Specifically disclosed are compositions comprising acellular, pulverized dermis combined with at least one glycosaminoglycan and/or gelatin. The subject compositions provide for improved retention of the composition at the site of implantation. Also disclosed are medical applications using the disclosed compositions, such as cosmetic enhancement or filling in of voids due to abnormalities, injuries, surgery, or aging. In addition, kits comprising at least one container of a freeze-dried, particulate tissue and at least one container of a glycosaminoglycan, or crude platelet extract and used thereof as a wound treatment/dressing, are disclosed.

  • Publication number: 20030192995
    Abstract: This invention solves problems associated with prior-art soft-dock mechanisms by placing all active components of a soft-dock system on the chaser side of the mechanism, leaving the target side of the mechanism completely passive (i.e., requiring no power expenditure or self-actuated moving parts to operate). In particular, the active components are supported on the end of a flexible cable attached to the probe, or chaser, side of the device. These components act as a sort of spring-loaded “trap.” Once the end of the probe passes into a receptacle on the target side, the mechanism is triggered, engaging it in such a way that it can no longer be pulled out of the receptacle until it is reset. The soft-docking cable may be replaced with a rigid, semi-rigid or jointed post that is used to bring a capture mechanism into engagement with its corresponding receptacle or receiving structure.
