  • 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: 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.

  • Patent number: 5055763
    Abstract: A battery charger device and method including a charging circuit having a source of charging energy and connections for installing one or more batteries to be charged, the device having a controllable switch associated with each battery to be charged and a microprocessor for controlling the switches to establish a charging sequence of distinct repeated charging periods for each battery, a display device associated with each battery under control of a microprocessor for individually indicating the charging status of each battery, the microprocessor having inputs at which various parameters with respect to the batteries being charged are applied such as battery voltages, ambient temperatures and charging currents, the microprocessor being programmed to terminate a voltage charging operation with respect to any one or more of the batteries if the measured difference between the charging and non charging voltage of any one or more of the batteries during succeeding charging periods exceeds some predetermined valu
