    摘要： An apparatus for ablating at least a portion of an interior of a body structure includes a catheter with a catheter interior and a port formed in a body structure of the catheter. An ablation energy delivery device is at least partially positioned in the catheter interior. The ablation energy delivery device is configured to be advanced through the port into the interior of the body structure to a selected tissue site and deliver an ablation energy to the selected site. The ablation energy delivery device is configured to be coupled to an ablation energy source. A sensor is coupled to the ablation energy source. The sensor is positionable in the interior of the body structure and measures an impedance of at least a portion of the selected tissue site. A conductive medium introduction member is coupled to a source of a conductive medium and the catheter. A feedback control means is coupled to the sensor and the conductive medium source. The feedback control means provides a controlled delivery of the conductive medium to the selected tissue site in response to a level of measured impedance. A cable coupled to the ablation energy delivery device.

    摘要： An apparatus for treating air way obstructions, includes a first arm including a proximal end and a distal end, the first arm distal end is inserted into the throat and positioned adjacent to a back surface of the tongue. A second arm has a proximal end and a distal end. The second arm is positioned under the jaw. A coupling member couples the first arm with the second arm, permitting rotational movement of each arm about a longitudinal axis of the coupling member. A plurality of RF electrodes are positioned in the first arm. The plurality of RF electrodes are advanced into the back of the tongue and retracted out of the tongue and into the first arm, ablating a selected area of the back of the tongue.

    摘要： A device for the ablation of tissue for use with the fingers of a human hand and a radio frequency power supply and controller providing a source of radio frequency energy and controls for controlling the application of radio frequency energy to the device comprising a handle sized so that is adapted to be grasped and supported by the human hand and having proximal and distal extremities. A single conductive needle formed of a conducting material is disposed in the distal extremity of the handle. An edge card is mounted in the handle and has edge mounted contacts with circuitry connected thereto. An edge mount board connector is mounted in the handle and is removably secured to the edge mounted contacts of the edge card. A cable is connected to the edge mount connector and extends from the proximal extremity of the handle and is adapted to be coupled to the radiofrequency power supply and controller. A second printed circuit board is mounted in the handle in a spaced-apart position from the edge card. A flex cable having conductive leads carried thereby extends between the edge card and the printed circuit board and is physically and electrically connected to the edge card. The proximal extremity of the needle is secured to the printed circuit board and makes electrical connections therewith.

    摘要： A tissue ablation apparatus for minimally invasive treatment for disorders of the upper airway by the treatment of soft tissues in the upper airway comprising a hand-held device adapted to be held by the human hand. Radio frequency energy is delivered to the hand-held device. The hand-held device comprises a housing having a handle portion adapted to be grasped by the human hand and a probe portion. At least one guide tube is mounted in the probe portion and has a bore extending therethrough. A carrier block is slidably mounted in the housing relative to the guide tube. At least one needle assembly is mounted in the carrier block assembly and is movable with the carrier block assembly. The at least one needle assembly extends distally of the carrier block and is slidably disposed in the at least one guide tube. A slider is mounted on the housing exterior of the housing for slidable movement longitudinally of the housing and is adapted to be grasped by the thumb of the hand holding the housing. The slider is connected to the carrier block whereby when the slider is moved distally, the carrier block with the needle assembly is moved in the guide tube distally of the guide tube for entrance into the soft tissue.
