    摘要: The present invention is a method for treating bony defects. The method involves contacting the bony defect with a formable composition and allowing the formable composition to solidify. The formable composition is comprised of 2-40% of reconstituted fibrillar atelopeptide collagen and 60-98% calcium phosphate mineral by weight exclusive of moisture. After the formable composition is placed in intimate contact with the bony defect, it is allowed to solidify until it acquires an additional characteristic selected from the group consisting of a compressive modulus of at 10 N/cm.sup.2 or a tensile strength of at least 1 N/cm.sup.2. The method can be used to repair a variety of bony defects such as bone non-union, fresh fractures, periodontal bony pockets, tooth extraction sockets and jaw cysts. Further, the composition can be used to augment an alveolar ridge.

    摘要: Medical devices, and more particularly, devices, methods and compositions for sealing tissue puncture openings of patients after surgical operations are provided. A puncture wound sealing apparatus includes a positioning device having a depth sensing mechanism capable of providing feedback to an operator for the precise placement of an implant that is preferably resorbable and swellable after implantation. Such an implant provides for efficient sealing of the tissue puncture opening thus avoiding complications after surgical procedures in which blood vessels are punctured.
