  • Patent number: 6648849
    Abstract: A system for injecting controlled release medicinal implants has a syringe-like injector body with a lumen and plunger. A needle is attached to the injector body and receives therein an injectable implant with an internal hollow. The implant is retained in the needle by friction, which is overcome by the plunger upon dispensing. As the plunger moves from the retracted position to the deployed position, it forces a medicament previously loaded into the injector body into the implant hollow and then pushes the implant out of the needle into the creature into which the needle has been inserted. The implant may contain a filler to absorb flowable medicaments to aid in their retention within the implant. As in known implants, the medicament is released gradually depending upon the dissolution rate of the implant body which is formed from a biodegradable material.

  • Publication number: 20030193104
    Abstract: A biocompatible tissue implant, as well as methods for making and using such an implant, is provided. Preferably, the tissue implant is bioabsorbable. The tissue implant comprises one or more layers of a bioabsorbable polymeric foam having pores with an open cell structure. The tissue implant also includes a reinforcement component which contributes both to the mechanical and the handling properties of the implant. Preferably, the reinforcement component of the instant invention is bioabsorbable as well. The tissue implant of the present invention can be used in connection with the surgical repair of soft tissue injury, such as injury to the pelvic floor.

  • Patent number: 6503259
    Abstract: A surgical fastening system includes a fastener having a plurality of individual fastener pairs each having a piercing element with a pin that pierces the tissue to be repaired and a receiver portion that interlocks with the pin of a corresponding piercing element. A fastener dispenser holds the piercing elements and receiver elements in relative juxtaposition and in a predetermined geometric configuration, such as a circle. After the tissues to be joined are positioned between the piercing and receiving elements held in the dispenser, the dispenser is adjusted to draw the elements together capturing the tissue therebetween. The dispenser then pushes the piercing elements through the tissue and into the receiving elements causing the elements to interlock. Because the anastomosed junction is formed by a plurality of independent pairs, the junction retains flexibility. When used to anastomose a tubular organ, the fastener allows radial expansion of the organ permitting peristalsis.

  • Patent number: 6319258
    Abstract: This invention describes a rivet applier and rivet clip for delivering orthopedic fasteners into a patient. The rivet applier inserts the rivet body then drives a pin into the rivet body to fix the rivet in position. The device comprises a body with a handle, trigger and applier barrel. The rivet applier contains a loader and firing pin to advance and deploy rivets. The applier barrel of the rivet applier is attached to a rivet clip into which rivets may be loaded. The rivets are contained in the body of the rivet clip and loaded into the barrel of the rivet clip through a chamber. The loader of the rivet applier advances the rivet to the end of the barrel. The firing pin advances the rivet body into final position and inserts the rivet pin into the rivet.

  • Patent number: 6273893
    Abstract: This invention describes a rivet applier delivering orthopedic fasteners into a patient. The rivet applier inserts the rivet body then drives a pin into the rivet body to fix the rivet in position. The rivet applier contains a hammer, hammer spring, firing pin and receiver to deploy rivets. The hammer of the rivet applier is attached to loading grips. The loading grips cock the hammer. A rivet is inserted into the receiver. Upon releasing the hammer, the hammer drives the firing pin and the firing pin inserts the rivet pin into the rivet.
