  • Publication number: 20100158887
    Abstract: A method of treatment of native, non-denatured tissue to increase resistance to tearing, fissuring, rupturing, and/or delamination, comprising the step of: contacting at least a portion of the tissue with an effective amount of a reagent that increases crosslinks in the tissue.
    Type: Application

  • Publication number: 20080260712
    Abstract: A method of improving the resistance of collagenous tissue to mechanical degradation in accordance with the present invention comprises the step of contacting at least a portion of a collagenous tissue with an effective amount of a crosslinking reagent. Methods and devices for enhancing the body's own efforts to stabilize discs in scoliotic spines by increasing collagen crosslinks. This stability enhancement is caused by reducing the bending hysteresis and increasing the bending stiffness of scoliotic spines, by injecting non-toxic crosslinking reagents into the convex side of discs involved in the scoliotic curve. Alternatively, contact between the tissue and the crosslinking reagent is effected by placement of a time-release delivery system directly into or onto the target tissue.

  • Publication number: 20030049301
    Abstract: A method of improving the resistance of collagenous tissue to mechanical degradation in accordance with the present invention comprises the step of contacting at least a portion of a collagenous tissue with an effective amount of a crosslinking reagent. The crosslinking reagent includes a crosslinking agent such as genipin and/or proanthrocyanidin. Further, the crosslinking reagent may include a crosslinking agent in a carrier medium. The collagenous tissue to be contacted with the crosslinking reagent is preferably a portion of an intervertebral disc or articular cartilage. The contact between the tissue and the crosslinking reagent is effected by injections directly into the select tissue using a needle. Alternatively, contact between the tissue and the crosslinking reagent is effected by placement of a time-release delivery system such as a gel or ointment, or a treated membrane or patch directly into or onto the target tissue. Contact may also be effected by, for instance, soaking.

  • Patent number: 4759769
    Abstract: An artificial disc for a human spine. The disc has upper and lower members hinged together at their rear portions and biased apart at their fronts by stiff coil springs. Rear stop surfaces limit the opening movement of the members. Vertically projecting tabs at the front and side of each member are rigidly screwed to the adjacent vertebrae. Tolerances in the hinge allow limited side to side rocking. The disc and screws are made of titanium alloy or cobalt chrome alloy. In a modified version a hinge pin is replaced by cables tying the members together.
