Abstract
A surface ablation system includes an electrosurgical generator, and elongated shaft, a plug, and a circuit assembly. The elongated shaft includes a proximal end portion and a distal end portion. The plug is supported on the distal end portion of the elongated shaft. The circuit assembly is supported on the plug and in electrical communication with the electrosurgical generator. The circuit assembly includes spaced-apart traces positioned in arrays about the plug. Each of the traces is configured to emit electrosurgical energy along the arrays to treat tissue positioned adjacent to the traces.
