  • Patent number: 6015410
    Abstract: A bioabsorbable surgical implant for use in supporting soft tissue in a superior position in the body is described. The surgical implant includes a shaft that connects the implant to a bone or hard tissue and a head secured to the shaft. The head of the implant has a concave lower surface so that a suture (or sutures) can easily be wound around the shaft below the head and locked to this position by tightening the head against bone or hard tissue and by pushing or turning the shaft into the bone or hard tissue. The connected shaft and head are formed from a resorbable polymer, copolymer, polymer alloy or composite, which maintains a specified strength for a period of time at least equal to a healing period for the patient. Thereafter, the surgical implant is substantially resorbed by the body over a period of time needed for healing.
