  • 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.

  • Patent number: 6013093
    Abstract: This invention is a blood clot filter having an anchoring portion (402) which includes a generally cylindrical self-expanding body. A generally conical filtering portion (400) is axially aligned with the cylindrical body (402), has an open proximal end (406) coupled to a distal end of the anchoring portion, and an apical distal end (404). In a preferred embodiment, the filter portion (400) is formed from strands (410) of resilient material that extend from the apical distal end (404) to the open proximal end (406). The strands (410) form twisted pairs (408) that converge at the apical distal end (404). The strands (410) diverge from the twisted pairs (408) in crossing paths to form a pattern of open filtering cells (A)(B)(C). The filter also has hooks (413) coupled to the anchoring portion (402) and formed from compliant material having an original shaped that bends under stress yet returns to its original shaped when unstressed.
