ABSTRACT:
A shaped conductive core electrode member having an elongated curved sharp leading cutting edge forming part thereof for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member having a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator. The second end terminates in an electrode support member which is operatively connected to or forms an integral part of the shaped electrode as an active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core. The bifurcated arm is covered with an insulative material except at the distal end where the shaped electrode is located. The electrode support member includes the shaped electrode having a sharp leading cutting edge and an opening extending therethrough for rigidly operatively mounting the shaped conductive core electrode member on the conductive core of the support member. The shaped conductive core electrode member may have openings and/or ridges or grooves formed in the side wall portion thereof. A method for incising and vaporizing tissue, such as prostate tissue and bladder tumors, using the shaped electrode for a resectoscope is also shown.
