    摘要: The suture is released by opening and withdrawing the tip from the guide. The suture is recovered by using the guide to redirect the tip and puncturing the tissue opposite the first point of insertion. The tip grasps the suture and pulls the suture through the guide. The suture is pulled outside the wound, providing for rapid closure of the surgical incision. The guide is insertable within the wound to be closed and guides the surgical instrument at a predetermined angle from the longitudinal axis of the guide for optimum wound closure. The surgical instrument and method may be used to advantageously shorten and strengthen ligaments. For example, by gathering and reinforcing the round ligament that supports a woman's uterus with suture materials, surgeons can reposition and stabilize a retroverted uterus. Other devices may be also used in connection with retracting and reinforcing connective tissue. For example, rather than relying entirely on suture material to hold connective tissue in a retracted state, a device having one or more anchors may be inserted into connective tissue.

    摘要: An implantable cardioversion or defibrillation lead provided with a large surface, carbon fiber electrode. The lead takes the form of an elongated tubular braid of carbon fiber, provided with a central core of insulating plastic. Over the majority of the braid's length, it is covered by an outer sheath of insulating plastic as well, serving as a lead conductor. At its distal end, the braid is not covered, and the exposed portion of the braid serves as the electrode.
