Connective-tissue-based or dermal-tissue-based grafts/implants
The present invention is directed to a composition comprising a matrix suitable for implantation in humans, comprising defatted, shredded, allogeneic human muscle tissue that has been combined with an aqueous carrier and dried in a predetermined shape. Also disclosed is a tissue graft or implant comprising a matrix suitable for implantation in humans, comprising defatted, shredded, allogeneic human muscle tissue that has been combined with an aqueous carrier and dried in a predetermined shape. The composition and/or tissue graft or implant of the invention is usable in combination with seeded cells, a tissue growth factor, and/or a chemotactic gent to attract a desired cell.
IMPLANTS HAVING A DRUG LOAD OF AN OXYSTEROL AND METHODS OF USE
Provided is a compression resistant implant configured to fit at or near a bone defect to promote bone growth. The compression resistant implant comprises a biodegradable polymer in an amount of about 0.1 wt % to about 20 wt % of the implant and a freeze-dried oxysterol in an amount of about 5 wt % to about 90 wt % of the implant. Methods of making and use are further provided.

MRI and CT contrast-enabled composite implants for image-guided tissue regeneration and therapy
A composite implant for providing simultaneous magnetic resonance imaging (MRI) and computed tomographic (CT) imaging contrast is disclosed. The composite implant is formed of a calcium compound in the form of nano or microparticles doped with a first dopant configured to provide MRI contrast and a second dopant configured to provide CT contrast. The calcium compound is loaded onto a polymer gel matrix and lyophilized to form a mass with 3-dimensionally interconnected porosity, configured to provide tissue integration and proliferation sites. Methods of forming the composite implant are also disclosed. The implant could be a scaffold or bead structured to enable treatment of human or animal patient for bone/cartilage injury or defect by implantation, with MRI and CT monitoring.

Bone graft substitute containing a temporary contrast agent and a method of generating such and a method of use thereof
A bone graft substitute for use in orthopedic bone grafting procedures comprising a radiolucent bone graft substitute combined with a temporary radiopaque agent. Methods of making and using the composition are also disclosed. Bone graft substitutes have become an effective means of regenerating bone in orthopedic procedures where bone loss results from surgically created defects or traumatic injury to the bone. Bone graft substitutes include mineral-based materials such as hydroxyapatite, calcium phosphates, and calcium phosphosilicates as well as allograft-derived materials and xenograft-derived materials such as collagen-based matrices and demineralized bone matrices.
