  • Patent number: 11197905
    Abstract: A composition includes a target pharmaceutical or biological agent, a solution containing the target pharmaceutical or biological agent, and substrate that is soluble in the solution. The substrate is capable of being solidified via a solidification process and the solidification process causes the substrate to become physically or chemically cross-linked, vitrified, or crystallized. As a result of the solidification process, particles are formed. The target pharmaceutical or biological agent within the solution retains proper conformation to ultimately produce a desired effect.

  • Patent number: 11007296
    Abstract: A drug-eluting self-retaining suture comprises a filament, a plurality of retainers, and a drug impregnated in or coated on the filament. The shape and distribution of retainers modifies the in vivo release kinetics of the drug. The drug release kinetics may be modified uniformly or region by region. The self-retaining suture may for example be used for reattaching severed nerves and release nerve growth factor or other regeneration accelerating agents into the region of the nerve injury.

  • Patent number: 7338655
    Abstract: The subject invention is related to a cell-mediated gene therapy treatment for orthopedic disease using a member belonging to the transforming growth factor-? (TGF-?) superfamily. TGF-? gene therapy as a new treatment method for degenerative arthritis is demonstrated. After transfection of TGF-? cDNA expression vectors into fibroblasts (NIH 3T3-TGF-?1), the cells were injected into rabbit achilles tendon and knee joints with artificially-made cartilage defects. Intratendinous injections were performed to determine the optimal concentration for in vivo expression. Partially defected cartilage model was made to simulate degenerative arthritis of the knee joint. The partial cartilage defect treated with the cell-mediated gene therapy procedure was covered by newly formed hyaline cartilage which indicates that the cells survived and stimulated matrix formation in this area. Completely denuded cartilage areas were covered by fibrous collagen.
