METHODS OF MANUFACTURING A DELIVERY SYSTEM FOR PROMOTING BONE GROWTH
First Claim
1. A method of manufacturing a delivery system for promoting bone growth comprising:
- forming a water-absorbing, water-gelatinizable material into a hollow tube or pouch;
inserting a bone growth promoting material into at least a portion of the tube or pouch; and
closing one or more initially open ends of the tube or pouch to 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.

Abstract
A method for manufacturing a delivery system that includes a bone growth promoting material encapsulated within a water-absorbing, water-gelatinizable covering used to promote bone growth in order to repair a bone defect and/or strengthen a weakened bone region. The delivery system may be shaped and sized in order to fit within a bleeding wound (e.g., one that is formed in the gingiva when a tooth is extracted). The covering may be formed of a gelatinizable-gauze (e.g., oxidized cellulose) that forms a gel-like material when moistened with water. The delivery system may be stored in a moisture resistant package prior to use.

16. A method of manufacturing a delivery system for promoting bone growth comprising:
-
forming a cellulose fabric into a hollow tube or pouch; inserting a bone growth promoting material into at least a portion of the tube or pouch; oxidizing the cellulose fabric in order to convert it into a water-absorbing, water-gelatinizable material that becomes gelatinous when contacted with water; and closing one or more initially open ends of the tube or pouch to 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. - View Dependent Claims (17, 18)

19. A method of manufacturing a delivery system for promoting bone growth comprising:
-
forming an oxidized cellulose gauze into a hollow tube or pouch; inserting a bone growth promoting material into at least a portion of the tube or pouch; and wet sealing and drying one or more initially open ends of the tube or pouch to 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. - View Dependent Claims (20)
