ABSTRACT:
Methods and apparatus are provided for welding or sealing blood vessels or tissue by capturing and stretching the tissue to alter its impedance characteristics prior to application of RF energy. The apparatus includes a working end including a perimeter jaw structure for engaging opposing ends of a section of a targeted blood vessel, and an interior jaw arm that passes through the plane of engagement and stretches the portion of the vessel intermediate the opposing ends, and two or more electrodes for applying RF current. The working end also may include one or more sensors providing signals to a power controller that modulates application of RF energy to the tissue.
