<p>This invention is a device (141) for the ablation of tissue with a source of RF energy, controls (13), a handle (142) sized to be grasped, and supported by the human hand. A single conductive needle (176) is disposed on the distal extremity of the handle. An edge card (156) is mounted in the handle, and has edge mounted contacts with circuitry connected thereto. An edge mount board connector (161) is mounted in the handle, and is removably secured to the edge mounted contacts of the edge card. A cable (163) is connected to the edge mount connector, coupled to the RF power supply, and controller. A second printed circuit board (172) is mounted in the handle in a spaced-apart position from the edge card. A flex cable (163) 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.</p> |
