Abstract: Disclosed herein is a modified tissue graft (120, 200, 300, 500, 630) with improved properties for tissue integration and regeneration. The tissue graft (120, 200, 300, 500, 630) has biological properties that are enhanced by removing lipids (615) and other contaminants (e.g., blood components, micro-organisms) using enzymes, enzyme aggregates, or immobilized enzymes. This application describes the process (10) for removing bio-contaminants while maintaining optimal biological properties.

Abstract: A patient-specific tissue graft and a method of forming the graft is disclosed. A 3D image of a patient's targeted implant site and surrounding anatomy is obtained to note the boundary of the implant site. A 3D model of the graft is formed by utilizing the boundary of the implant site, a surface curvature, extrapolated from the patient's target implant site surrounding anatomy, and a depth, defined by a plane parallel to a plane normal to a point of curvature at the surface. Donor tissue is chosen that has a location with a close approximation to the 3D model of the graft. The donor tissue is visualized to determine a cutting path to shape or modify the architecture of the tissue. A cutting path is determined with imaging technology and computational methods. The graft is cut out of the donor tissue utilizing a fluid cutting process.

Abstract: A live tissue storage solution is formed of an aqueous culture medium including additives, inorganic salts and nutrients. The additives preferably include amino acids including but not limited to L-Arg, L-Cys, Gly, L-His, L-Ile, L-Lys, L-Leu, L-Met, L-Phe, L-Ser, L-Try, L-Try, and L-Val. The inorganic salts preferably include calcium chloride, sodium chloride, magnesium sulphate, sodium bicarbonate, sodium phosphate. The nutrients preferably include glucose, choline, folic acid, nicinamide, riboflavin, which are known to maintain cell culture. Examples include Dulbecco's Modified Eagle Medium DMEM or Minimal Essential Medium MEM with or without serum. The culture medium contains additives to reduce, inhibit, or mitigate lipid oxidation, lipotoxicy, lipid-induced responses, and lipid inflammation.
