RADIOFREQUENCY PROBES WITH RETACTABLE MULTI-TINED ELECTRODES

摘要

A retractable, multi-tined radio frequency (RF) probe operable for applying RF energy to tissue for therapeutic purposes, the probe having a tubular elongate member defining an interior and having a proximal end and an opposite distal end; a handle element at the proximal end of the elongate member; and an electrode element at the distal end of the elongate member, the electrode element comprising a tip portion and a plurality of tines, each of the plurality of tines being positionable in a retracted configuration within the interior of the top portion and/or the elongate member and in a deployed configuration that extends outward of the top portion.
