ABSTRACT:
A device for the ablation of tissue for use with the human hand and a radio frequency power supply and controller providing a source of radio frequency energy and a control for controlling the application of radio frequency energy to the device. The device includes a handle sized so that is adapted to be grasped by the human hand and has proximal and distal extremities. A needle formed of a conducting material has proximal and distal extremities. The proximal extremity of the needle is mounted on the distal extremity of the handle so that it is insulated from the handle. Conductors are carried by the handle and are connected to the needle and extend from the handle and are coupled to the radio frequency power supply and controller for supplying radio frequency energy to the needle. A temperature sensor is carried by the handle and is 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.
