  • Publication number: 20210315703
    Abstract: The invention is directed towards a process for implanting a cartilage graft into a cartilage defect and sealing the implanted cartilage graft with recipient tissue by creating a first bore down to the bone portion of the cartilage defect, creating a second shaped bore that is concentric to and on top of the first bore to match the shape and size of the cartilage graft, treating the first bore and the second shaped bore at the defect site with a bonding agent, treating the circumferential area of the cartilage graft with a bonding agent, inserting the cartilage graft into the defect site and wherein the superficial surface of the cartilage graft is at the same height as the surrounding cartilage surface. The first and second bonding agents may be activated by applying a stimulation agent to induce sealing, integration, and restoration of the hydrodynamic environments of the recipient tissue.

  • Publication number: 20190001022
    Abstract: The invention provides methodologies and apparatus for producing acellular soft-tissue implants, both in small quantities and in commercializable quantities. Such soft-tissue implants include vascular graft substitutes. An acellular graft is produced by subjecting the tissue sample to an induced pressure mediated flow of an extracting solution, followed by inducing a pressure mediated flow of a treating solution, then washing the treated tissue to produce the acellular graft. The acellular grafts produced are uniform and nonimmunogenic. The inventive method allows for the production of multiple decellularized soft tissue implants, where processing time is significantly less than prior art processes and the number of implants produced per day is increased over prior art processes. In clinical use, the decellularized grafts produced exhibit significantly improved in long-term durability and function.

  • Patent number: 9936688
    Abstract: The invention provides methodologies and apparatus for producing devitalized soft-tissue implants where the implant retains metabolically non-viable and/or reproductively non-viable cells, and preferably retains large molecular weight cytoplasmic proteins, such implants produced both in small quantities and in commercializable quantities. Such soft-tissue implants include vascular graft substitutes. A devitalized graft is produced by subjecting the tissue sample to an induced pressure mediated flow of an extracting solution, optionally followed by inducing a pressure mediated flow of a salt solution, then washing the tissue to produce the devitalized graft. The devitalized grafts produced are uniform and non-immunogenic. The inventive method allows for the production of multiple devitalized soft tissue implants, where processing time is significantly less than prior art processes and the number of implants produced per day is increased over prior art processes.

  • Publication number: 20170319357
    Abstract: The invention provides a plasticized tissue or organ that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in natural tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. Replacement of the chemical plasticizers by water prior to implantation is not required and thus, the plasticized bone or soft tissue product can be placed directly into an implant site without significant preparation in the operating room.

  • Patent number: 9744043
    Abstract: The invention is directed to producing a shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. The invention relates to a process for repairing a cartilage defect and implantation of a cartilage graft into a human or animal by crafting the cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation.
