An intradiscal shield and an exterior shield configured to prevent re-herniation and to provide structural integrity to a spinal defect within or on a spinal disc. An insertion instrument to insert the intradiscal shield within the spinal defect and attach the intradiscal shield or exterior shield to the spinal disc. The insertion instrument having a distal tip for spraying a protein crosslinking reagent within the spinal defect. The exterior shield configured for attaching to the exterior wall of the spinal disc and blocking an exterior opening of the spinal defect.

Shield for spinal defect

A protein crosslinker delivery device includes a body and a protein crosslinker held in a synthetic or natural biodegradable polymer. The body, a coating on the body, or an attachment to the body can contain the protein crosslinker holding biodegradable polymer. The release rate of the crosslinker and total amount of crosslinker released can be controlled by varying the concentration of the crosslinker and by varying the composition and structural characteristics of the degradable polymer. Surface eroding, bulk eroding and naturally occurring biodegradable polymers can be used in conjunction with a variety of nontoxic or minimally-toxic protein crosslinking agents. The devices can be used to treat mechanically damaged, deformed, and nutritionally deficient connective or soft tissues such as the knee meniscus, the spinal disc, the cornea, ligaments and tendons, the soft palate, and skin.

Crosslinker enhanced repair of connective tissues

A method of treating snoring and/or OSA in a subject in need of such treatment. The method includes crosslinking proteins of the subject's soft palate tissue or pharynx tissue. The crosslinking can occur by contacting the soft palate or pharynx tissue with a crosslinking reagent. In addition, the crosslinking can occur without heating, contracting or denaturing of the tissue, or any combination thereof.

Tissue crosslinking for treatment of snoring and obstructive sleep apnea

A method of treating a tear in a knee meniscus of a patient. The method includes exposing the torn knee meniscus to a protein crosslinker during surgery to repair the tear. Also provided is a fixation device for the surgical repair of tears of the meniscus of the knee, where the device contains one or more protein crosslinking reagents.

Crosslinker enhanced repair of knee meniscus

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.

Use of non-toxic crosslinking reagents to improve fatigue resistance and reduce mechanical degradation of intervertebral disc and other collagenous tissues

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. Methods and devices that use crosslinking agents for increasing the permeability of an intervertebral disc, improving fluid flux to the intervertebral disc, and increasing the biological viability of cells within the intervertebral disc are provided.

Non-toxic crosslinking reagents to resist curve progression in scoliosis and increase disc permeability

Improved methods and compositions for the treatment of native tissues with crosslinkers are provided. The methods and compositions will find particular use in increasing resistance to tearing, fissuring, rupturing, and/or delamination.

Formulations for nonsurgical exogenous crosslink therapy

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.

Direct application of non-toxic crosslinking reagents to resist progressive spinal degeneration and deformity

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 and other progressively deforming spines by increasing collagen crosslinks. This stability enhancement is caused by reducing the bending hysteresis and increasing the elasticity and bending stiffness of progressively deforming spines, by injecting non-toxic crosslinking reagents into the convex side of discs involved in the potential or progressing deformity 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. Methods and devices that use crosslinking agents for increasing the permeability of an intervertebral disc, improving fluid flux to the intervertebral disc, and increasing the biological viability of cells within the intervertebral disc are provided.
