  • Cartilage-derived implants and methods of making and using same
    Patent number: 11938245
    Abstract: Cartilage fibers and implants made therefrom are disclosed, with and without cartilage particles. Methods for making the cartilage fibers and the implants containing them are also disclosed. The implants may be pre-shaped, may be reshapable and, when implanted in a cartilage defect, the implants have good shape retention, little swelling, completely fill the cartilage defect and resist migration from the defect upon irrigation.
    Type: Grant
