20090069901 | CARTILAGE ALLOGRAFT PLUG - The invention is directed toward a cartilage repair assembly comprising a shaped allograft structure of subchondral bone with an integral overlying cartilage cap which is treated to remove cellular debris and proteoglycans and milled allograft cartilage in a bioabsorbable carrier. The shaped structure is dimensioned to fit in a drilled bore in a cartilage defect area so that either the shaped bone or the cartilage cap engage the side wall of the drilled bore in an interference fit and is in contact with a milled cartilage and biocompatible carrier mixture allowing cell transfer throughout the defect area. A method for inserting the shaped allograft structure into a cartilage defect area is also disclosed. | 03-12-2009 |
20100015202 | CANCELLOUS CONSTRUCT WITH SUPPORT RING FOR REPAIR OF OSTEOCHONDRAL DEFECTS - The invention is directed toward an osteochondral repair assembly comprising a shaped allograft construct comprising an unbalanced barbell-shaped cylindrical cancellous bone primary member formed with a mineralized cylindrical base section having a smaller diameter cylindrical stem leading to a second cylindrical section which is demineralized. A mineralized ring-shaped support member is forced over the compressed demineralized second demineralized the aperture of the ring-shaped member to fit around the stem with one ring surface being adjacent the bottom surface to the second cylindrical section and the opposite ring surface being adjacent the upper surface of the mineralized cylindrical base section. | 01-21-2010 |
20100304487 | SOFT TISSUE PROCESSING - The present invention is a process for preparing soft tissue such as tendons, ligaments, cartilage, fascia, dermis, human valves and human veins for implant in a human and removes cellular components and forms an decellular matrix having as major components collagens and elastins while sterilizing the tissue. The process comprises the following steps: | 12-02-2010 |
20110059178 | Tissue Engineered Meniscus Repair Composition - A meniscus repair composition for application to a meniscus defect site to promote growth of new tissue at the meniscus defect site is provided. The composition comprises: from about 10 to about 50 percent by weight of allograft meniscus particles having an average particle size of from about 10 μm to about 500 μm; a carrier selected from the group consisting of sodium hyaluronate, gelatin, collagen, polyethylene glycol, glycerin, carboxymethylcellulose, dextrose, blood derivatives, aqueous solutions thereof, and mixtures thereof; and a curing agent. The curing agent may be the carrier where the carrier is cross-linkable. When introduced to a defect site in a meniscus and cured, the composition will not flow away from the defect site, and the composition is non-adhering to the defect site after it is cured. | 03-10-2011 |
20110060412 | Tissue Engineered Meniscus Repair Composition - A meniscus repair composition for application to a meniscus injury to promote growth of new tissue at the meniscus injury site is provided. The composition comprises: from about 10 to about 50 percent by weight of allograft meniscus particles having an average particle size of from about 10 μm to about 500 μm; and a carrier comprising a solid fibrin web matrix. When introduced to a defect site in a meniscus, the composition is non-adhering to the defect site. A method for repairing a meniscus injury comprises administering a meniscus repair composition to the injury site. | 03-10-2011 |
20110196508 | CARTILAGE REPAIR MIXTURE CONTAINING ALLOGRAFT CHONDROCYTES - The invention is directed toward a sterile cartilage defect implant material comprising milled lyophilized allograft cartilage pieces ranging from 0.01 mm to 1.0 mm in size in a bioabsorbable carrier taken from a group consisting of sodium hyaluronate, hyaluronic acid and its derivatives, gelatin, collagen, chitosan, alginate, buffered PBS, Dextran or mixed polymers with allograft chondrocytes added in an amount ranging from 2.5×10 | 08-11-2011 |
20140058527 | CARTILAGE REPAIR MIXTURE CONTAINING ALLOGRAFT CHONDROCYTES - The invention is directed toward a sterile cartilage defect implant material comprising milled lyophilized allograft cartilage pieces ranging from 0.01 mm to 1.0 mm in size in a bioabsorbable carrier taken from a group consisting of sodium hyaluronate, hyaluronic acid and its derivatives, gelatin, collagen, chitosan, alginate, buffered PBS, Dextran or mixed polymers with allograft chondrocytes added in an amount ranging from 2.5×10 | 02-27-2014 |
