Abstract
An improved catheter system having a movable bipolar electrode pair means enclosed within an inflatable balloon capable of treating a tissue of a patient. In one embodiment, a catheter suitable for radiofrequency ablation of cardiac tissues comprises an electrode means having a first movable electrode positioned at an elongated open groove and a second electrode to form a bipolar electrode pair, wherein the electrode means is mounted at a shaft distal tip section and is completely enclosed within the inflatable balloon. RF energy is delivered to the first electrode through a first electrical conducting means, transmitted from the first electrode to the second electrode, and returned from the second electrode to said generator means through a second electrical conducting means for generating heat uniformly inside the inflatable balloon.
