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