RADIO FREQUENCY DETECTORS WITH FOLDABLE MULTIPLE BLADE ELECTRODES

Abstract

A collapsible multi-blade radio frequency (RF) probe operative to apply radio frequency energy to tissue for therapeutic purposes, the probe having a tubular elongated shaft defining an interior and having a proximal end and an opposing distal end, a handle element at the proximal end of the elongated shaft, and an electrode element at the distal end of the elongated shaft, the electrode element including a tip portion and a plurality of blades, each of the plurality of blades being positionable in a collapsed configuration within the interior of the upper portion and / or the elongated shaft and in an expanded configuration extending outwardly from the upper portion.
