摘要: An RF ablation apparatus has a delivery catheter with distal and proximal ends. A handle is attached to the end of catheter. The an electrode deployment means where said includes retractable tip section comprising deployable portion one side having sharp edge. non-deployed state when it positioned in On other hand, distended deployed advanced out preformed shape while farther defines target along forward edge on electrode. slightly curvature or essentially straight shape. Said ultrasonic imaging capabilities.
