Abstract:
An electro-surgical device for tissue resection, comprising:an elongated body adapted to be coupled to a source of energy at a proximal end; a substantially U-shaped loop electrode; a pair of arms comprising a long axis, the pair of arms in a spaced relationship extending from a distal end of the elongated body to the loop electrode and defining a plane, the pair of arms surrounded by a first insulative coating along the long axis of each arm, the first insulative coating extending from the elongated body to the loop electrode, wherein the substantially U-shaped loop electrode connects the pair of arms at an angle relative to the plane, the loop electrode defining a pair of end sections and a base section, each end section coupled to an arm, the end sections comprising a conductive material and including a second insulative coating disposed thereon, the base section consisting of a continuous curve disposed between the end sections and comprising the conductive material free of the first and second insulative coatings, wherein energy applied to the electrode focuses energy emission for tissue resection at the continuously curved base section.
