  • Publication number: 20080281432
    Abstract: An implant for repair of a cartilaginous defect in a subject includes a collagen matrix charged with synovial cells. A method preparing an implant for repair of a cartilaginous defect in a subject includes obtaining a fluid containing synovial cells and charging the synovial cells to the matrix. A device for preparing a cell-charged implant includes a first chamber and a second chamber, the first and second chambers being separated by a membrane and a perforated filter. The membrane is adapted to collect cells from a cell-containing fluid introduced into the first chamber and the perforated filter is adapted to permit passage or diffusion of the fluid through the second chamber. A method for preparing a cell-charged implant utilizes the device.

  • Patent number: 7141072
    Abstract: A method of promoting regeneration of surface cartilage of a joint includes the steps of covering the area to be treated with a patch which includes a sheet of collagen membrane material. The collagen membrane material has at least one barrier layer to prevent passage of cells therethrough. The collagen membrane further includes a matrix layer predominantly of collagen II having an open sponge-like texture. The patch is fixed over the area to be treated, and the area is allowed to regenerate cartilage.

  • Patent number: 7132413
    Abstract: Compositions and methods are provided for preventing formation of thrombosis on a liquid-contacting surface of a liquid delivery system, such as a port, catheter or port-catheter system. The liquid delivery system is connected to a patient for delivery of a liquid to the patient. The method involves contacting the surface with a thrombosis-preventing liquid containing taurolidine, taurultam or a mixture thereof, the thrombosis-preventing liquid further containing an anticoagulant agent. In an alternative embodiment, the liquid-contacting surface of the delivery system is contacted with a solution containing an anticoagulant agent, and thereafter contacted with a solution containing taurolidine, taurultam or a mixture thereof.
