ELECTRO-CAUTERY CATHETER

摘要

This invention is an integrated catheter assembly for enabling diverse endoscopic in situ therapies. The assembly includes a catheter (12) with an irrigation fluid lumen, a distal electrode tip portion (20) that acts as a hemostat, and a cutting wire (23) for making incisions in or ablating tissue. A cutting wire hub (21) provides a sealing entrance for a cutting wire. An operator (24) enables the physician to displace the cutting wire between extended, and retracted positions. The cutting wire, and electrode are electrically isolated. The apparatus of the present invention allows the physician to make incisions in or ablate tissue using electrosurgery, irrigate tissue, and cauterize or coagulate tissue without having to remove the apparatus from the working channel of the endoscope.
