Abstract:
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 means for controlling the application of radio frequency energy to the device comprising a one-piece unitary handle having an exterior surface sized so that it is adapted to be grasped and supported by two fingers of the human hand and having proximal and distal extremities, a single conductive needle formed of a conducting material and having proximal and distal extremities, means for mounting the proximal extremity of the needle in a molded static position on the distal extremity of the handle so that it is the sole needle carried by the handle and is insulated from the handle and having a portion that extends distally of the handle, conductive means including a printed circuit board carried by the handle and connected to the needle and extending from the handle and adapted to be coupled to the radio frequency power supply and controller for supplying radio frequency energy to the needle and control means carried by the handle and adapted to be coupled to the radio frequency power supply and controller for sensing the application of radio frequency energy to the tissue for controlling the application of radio frequency energy to the needle, said control means being free of controls on the exterior surface of the handle.
