This disclosure is directed to methods for reconstructing an unstable triangular fibrocartilage complex (TFCC). Exemplary methods include preparing, delivering, and fixating a graft within a distal radioulnar joint in a manner that restores the functionality to the TFCC, thereby improving the joint kinematics of the radioulnar joint.

The present invention relates to a living fatty material from which immunity is removed, and a method for manufacturing the same, and more specifically, to a living fat tissue from which immunity is removed and to a method for manufacturing the same, comprising the steps of collecting fat tissues; irradiating the fat tissues with 20 to 500 kGy of gamma (γ) rays; and applying centrifugal separation of the fat tissues irradiated with gamma rays.

Systems and methods for identifying a cell suspension with therapeutic potential for skin regeneration and related compositions are disclosed herein. In some variations, a method may include receiving a cell suspension that comprises a population of viable cells and non-viable cells, then measuring a value indicative of at least one characteristic of the cell suspension, such as but not limited to one or more of total cell count, total cell viability, cell viability percentage, and median live cell diameter. A cell suspension composition having therapeutic potential may comprise a cell suspension met certain thresholds relating to total cell count, total viable cell count, cell viability percentage, and median live cell diameter.

The invention is directed to a biological bandage derived from fish skin (e.g. tilapia skin) that can be used with healing of wounds such as burn wounds. The edible property of the fish skin biological bandage according to various embodiments makes it suitable for both human and veterinary medicine.

Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. Tissue augmentation constructs can include various blocks and scaffolds, among other formations. The present disclosure includes, among other disclosures, methods for using tissue augmentation scaffolds, including folding scaffolds, and descriptions and methods associated with extra-wide tissue augmentation blocks.

The invention relates to a method of producing a decellularized tissue scaffold. The invention also relates to a tissue scaffold produced by said method. In particular, porcine tissue scaffolds. The method comprises reduced levels of anionic detergent, and avoids the use of animal derived protease inhibitors to produce a tissue scaffold with favourable properties.

The present disclosure relates to tissue matrix products. The products can includes tissue matrices that have holes or perforations located at certain positions to improve certain in vivo functions without substantial loss of strength or other important properties.

This invention is directed to systems and methods for treating a hernia by implanting a tissue graft material.

Compositions containing purified collagen biomaterial derived from tissues, for example, insoluble amnion, soluble amnion, soluble chorion of the human placenta, are provided. The collagen compositions can be used to promote wound healing, promote tissue regeneration, prevent or reduce scarring, reduce local inflammation, minimize tissue rejection, promote graft integration. Methods for using the collagen composition as a biomaterial implant for dermal filling, skin grafting, and hair transplantation are also provided.
