Patent ID: 8323339

Claim:
A method of manufacturing a delivery system for promoting bone growth comprising: forming a water-absorbing, water-gelatinizable material that becomes gelatinous and self-adhesive when moistened with water into a hollow tube or pouch having an initially open end; inserting a bone growth promoting material into the hollow tube or pouch through the initially open end; closing the initially open end of the tube or pouch; moistening the closed end with water so that it temporarily becomes gelatinous and self-adhesive; and drying the closed, moistened, and self-adhesive end to form a sealed end of the tube or pouch and thereby form a delivery system for promoting bone growth comprised of: an outer covering formed from the water-absorbing, water-gelatinizable material that defines an interior space; and the bone growth promoting material encapsulated within the interior space by the outer covering, wherein the outer covering becomes sticky and adhesive to tissue in a bone void when moistened with water.
