  • Processed soft tissue for topical or internal application
    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.

  • Technique for shrinking xenograft and allograft heart and vascular tissue
    Publication number: 20020082688
    Abstract: A process of applying thermal energy using a controlled regimen is described to reduce the size of biological xenograft and allograft heart and vascular tissue, particularly heart valves, which are used for implants by applying a controlled regimen of thermal energy, and the related implant products, apparatuses and systems. In a particular embodiment, a xenograft or allograft heart valve experiences size reduction and fits the size requirements of a recipient into whom the heart valve is being implanted.
