  • Patent number: 9216194
    Abstract: The present disclosure provides a biocompatible composite and method for its use in repairing tissue defects, including defects in cartilage. The biocompatible composite includes a fibrous polymeric component and a polymerizable agent, which is capable of forming the biocompatible composite in situ at the site of a tissue defect. In embodiments, the repair site at which the biocompatible composite is to be applied may be treated with a priming agent, permitting polymerization of the polymerizable agent to the tissue located at the repair site.

  • Publication number: 20110082389
    Abstract: A measuring system may provide quantitative information relating to condition of cartilage. Negative pressure may be applied to cartilage to induce flow of fluid from or through the cartilage. A level of negative pressure needed to induce a particular flow of the fluid may be employed to provide a quantitative indicia of cartilage condition. An averaged level of negative pressure measured over a period of time may be used to calculate hydraulic resistance of the cartilage.

  • Patent number: 7897165
    Abstract: The present invention relates to the covalent binding of a hydrogel to an extracellular matrix (ECM). The integration of the hydrogel with the tissue is superior to that in previous techniques. Moreover, unlike previous techniques, the present invention does not require a photoinitiator. Potential therapeutic applications include tissue repair and delivery of drugs or cells. The ECM is first exposed, then treated with a priming agent. Then a polymerizable agent is added and crosslinked to the ECM. Two primary embodiments of methods are disclosed. In the first, the priming agent is an oxidizer which creates tyrosyl radicals in the ECM, which are then bound by acrylate groups in the polymerizable agent. In the second, the priming agent contains aldehydes which bind amino groups in the ECM.
