Abstract
A tissue ablation system for ablating tissue is presented having independent sensing and ablation capabilities. A sensing wire is positioned distally to the ablation region and passed through the ablation device allowing independent movement. The ablation device can ablate a substantial portion of a circumferential region of tissue. The tissue ablation system comprises an ablation device comprised of an elongated catheter with a proximal region and a distal region and an ablation element located proximate the distal region of the catheter. A sensing device having an elongated body with a proximal portion and a distal portion is adapted to be positioned within a vessel at or near a vessel ostium, wherein the sensing device is adapted to be slidably received within a lumen of the ablation device. The sensing device may be shaped in various configurations.
