    Abstract: 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.

    Abstract: A stent for introduction into a portion of a urethra in a body of a patient. The urethra extends through a prostate and is formed by a wall having a diameter. The stent includes a longitudinally-extending body made from a material adapted for absorption by the body of the patient. The longitudinally-extending body has an expanded condition in which the body has a predetermined diameter greater than the diameter of the portion of the urethra extending through the prostate. The longitudinally-extending body is formed with a plurality of coils along the length thereof adapted to engage the wall of the urethra when the longitudinally-extending body is in the expanded condition. The longitudinally-extending body is provided with spaces between the coils to permit the wall of the urethra to extend therein and serve to anchor the longitudinally-extending body to the wall.
