  • Patent number: 10085796
    Abstract: A bipolar electrosurgical device includes a handle and an elongated end effector coupled to the handle. The end effector includes an elongated, insulating body having first and second electrodes disposed thereon. The first and second electrodes are separated at the distal end of the insulating body, and a cavity formed in the distal end of the effector is positioned between the first and second electrodes. A fluid-delivery tube is positioned on the body to deliver a conductive fluid to the distal end, adjacent the cavity. During use of the electrosurgical device, delivery of the conductive fluid facilitates formation of an electrical coupling between the electrodes via the tissue being treated.

  • Patent number: 9023040
    Abstract: A cutting device for tissue separation includes a cutting edge using electrical energy such as RF power that is coupled to, but thermally insulated from, a catheter in an elongated medical device. Thermal insulation between a ring-type cutting device and the catheter is provided by a gap, slots within the ring, and/or slanted slots within the ring. In one embodiment, tissue separation occurs by rotation of a ring-type electrically-powered cutting edge having internal cross-bar elements. In an alternate embodiment, tissue separation occurs by longitudinal movement of an offset electrically-powered cutting edge that is pressed against tissue by an inflatable balloon. In a further alternate embodiment, a cutting edge is coupled longitudinally to a catheter, is provided electrical energy by wired connection to the braided catheter, but is thermally isolated from the catheter.

  • Patent number: 8496652
    Abstract: A system for treating uterine disorders includes a balloon catheter having a cannula with a proximal end and a distal end, and an inflatable balloon secured over the distal end of the cannula. The device includes a heating assembly coupled with the distal end of the cannula and disposed inside the inflatable balloon, and an impeller disposed inside the heating assembly. In one embodiment, the heating assembly includes an elongated heating tube having a heating film covering an outer wall thereof, at least one fluid inlet extending though the outer wall and a fluid outlet located at a distal end of the elongated heating tube. The impeller is rotatable for drawing fluid through the at least one fluid inlet and into the elongated heating tube for heating the fluid, and discharging the heated fluid from the fluid outlet for circulating the fluid throughout the inflatable balloon.

  • Patent number: 7179254
    Abstract: An apparatus for ablating tissue, the apparatus having first and second opposing jaws operative to compress tissue to be allayed therebetween, the first jaw having a first ablation surface directing ablative energy into the tissue and the second jaw having a second ablation surface reflecting incident ablative energy into the tissue. The ablative energy may be ultrasonic, microwave, cryoablation, radio-frequency, photodynamic, laser, and cautery energy.
