Abstract
An electrosurgical device that can be used to remove pedunculated tissue structures such as polyps and certain uterine fibroids includes bipolar surface electrodes and a bipolar snare. The device includes a probe having a proximal end and a distal end, bipolar surface electrodes adjacent to the distal end of the probe, and a bipolar snare extending distally from the distal end of the probe and including first and second snare electrodes. The bipolar surface electrodes are separated from each other by a gap and extend over a portion of the distal end of the probe. Providing both a bipolar snare and bipolar surface electrodes advantageously reduces thermal spread from occurring (compared to the use of a monopolar snare) when using the snare to excise the tissue. The bipolar surface electrodes can be used to coagulate the point of excision.
