  • Patent number: 5833700
    Abstract: A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

  • Patent number: 5827291
    Abstract: An elongated suture anchor driver having a suture retaining means at its proximal end. The driver receives a suture anchor at its distal tip and has a throughbore for enabling suture attached to the suture anchor to pass through the driver from its distal end to its proximal end. The proximal end of the driver is provided with a channel and a fixed post for guiding the suture exiting from the throughbore into an annular recess. A spring loaded slidable cylindrical sleeve acts against the suture in the recess to frictionally retain the suture, thereby securing the suture anchor and suture within the driver.

  • Patent number: 5814066
    Abstract: Post catheterization arterial bleeding is reduced by introduction of a fibrin sealant, prepared from fibrinogen and thrombin, into the periarterial tissue surround the arteriotomy through which the catheter was inserted. The fibrin sealant is introduced as the catheter is withdrawn, which introduction may be accompanied by local pressure. The fibrin sealant, prepared from fibrinogen and thrombin, clots or "sets" to form a fibrin seal, reducing arterial bleeding and post catheterization difficulties.
