Publication number: 20230057906Abstract: Multiple component grafts are provided for treatment of tissue defects and comprise two or more components, each of which is a tissue-derived matrix and at least two of which are derived from different types of tissue. For example, a first component may be a matrix derived from cartilage tissue such as cartilage fibers with or without viable cells, cartilage particles with or without viable cells, or combinations of any two or more such cartilage-derived matrices. A second component may be a matrix derived from bone tissue such as mineralized or demineralized cortical bone fibers, viable cancellous bone matrix (e.g., cryopreserved or lyophilized chips, particulates, powder, sheets, putty, flowable fluid, etc.), demineralized or demineralized cancellous bone matrix (chips, particulates, powder, sheets, putty, flowable fluid, etc.), or combinations of any two or more of such bone-derived matrices. Also provided are methods for making and using such multiple component grafts.Type: ApplicationFiled: January 14, 2021Publication date: February 23, 2023Inventors: Marc Long, Eric J.

Publication number: 20230044661Abstract: Preserved tissue samples contain endogenous viable cells and retain or promote biological activity after being stored at temperatures above freezing for extended periods of time (e.g., from 14 days to 3 years). The preserved tissue samples are implanted in or on a subject and, after rehydration, they retain beneficial biological activity, promote beneficial biological activity, or both. The beneficial biological activity comprises promoting one or more of tissue healing, tissue growth, and tissue generation. Methods for preparing the preserved tissue samples include contacting a recovered tissue sample with one or more protectants, followed by lyopreservation. Suitable protectants include sugars, polyphenols, carotenoids, and combinations thereof. Preferred protectants include glucose, fructose, sucrose, trehalose, dextran, EGCG, and combinations thereof. The recovered tissue sample may be any of several possible issue types.Type: ApplicationFiled: December 17, 2020Publication date: February 9, 2023Inventors: Amy Ker-Ping Chang, Brooke Catalfamo, Michael Zbigniew Kubik, Subha Bhattacharyya, Eric J.

Patent number: 8906110Abstract: The invention is directed toward a cartilage repair assembly comprising a shaped allograft two piece construct with a demineralized cancellous cap and a mineralized cylindrical base member defining a blind bore with a through-going transverse bore intersecting the blind bore. The demineralized cancellous cap has a cylindrical top portion and a smaller diameter cylindrical stem extending away from the top portion which fits into the blind bore of the mineralized base member. The cap stem defines a transverse through-going bore which is aligned with the through-going bore of the base member to receive a cylindrical cortical pin holding the cap within the base member. The shaped structure is dimensioned to fit in a drilled bore in a cartilage defect area so that the assembly engages the side wall of the drilled bore in an interference fit.Type: GrantFiled: September 14, 2010Date of Patent: December 9, 2014Assignee: Musculoskeletal Transplant FoundationInventors: Eric J.

Publication number: 20100274362Abstract: Mixtures, such as gels or pastes, comprising freeze-milled cartilage particles and exogenous growth factors are used for repairing chondral defects. Such mixtures may be applied to constructs comprising cancellous bone for implantation at the defect site. Suitable growth factors include variants of FGF-2, particularly variants that include a sole amino acid substitution for asparagine at amino acid 111 of the ?8-?9 loop of the FGF-2 peptide. Such FGF-2 variants are released slowly and continuously at a constant rate from cartilage pastes. In other embodiments, the amino acid substituted for asparigine is glycine. Other variants that may be used include FGF-9 variants having truncated chains and a sole amino acid substitution in the ?8-?9 loop of the FGF-9 peptide either for tryptophan at amino acid 144 or for asparagine at amino acid 143.Type: ApplicationFiled: January 14, 2010Publication date: October 28, 2010Inventors: Avner Yayon, Katherine G.
