Abstract: This invention is a catheter (10) for ablating, and/or mapping tissue on the inner wall of a blood vessel; including a body portion (11), a tip portion (12) having a proximal section, and a distal section; the proximal section including a proximal ablation electrode (14), a proximal mapping electrode (18), and the distal section; including a distal ablation electrode (16), and a distal mapping electrode (19); wherein the tip portion is deflectable from a first, generally straight, configuration in which the proximal, and distal sections are substantially co-linear to a second, J-shaped, configuration in which the proximal, and distal sections are generally parallel with a separation therebetween substantially corresponding to the inside diameter of the blood vessel.

Abstract: A device, and method for performing cardiac ablations includes a therapeutic instrument, for example, an ablation catheter (10), to which is mounted a flexible, and braided electrode (14). The electrode configuration is selected so that it has a desired surface area for proper heat convection properties. RF energy (26) is delivered to the electrode to heat, thereby ablate local heart tissue, with the electrode having good convection abilities to protect against coagulation, embolisms, and other undesirable effects of ablation procedures.

Abstract: A medical device is disclosed which includes a deformable electrode device (12). In one illustrative embodiment, the deformable electrode is in the form of a braided member, at least a portion of which is electrically conductive. The braided member is extended over an elongated inner member (14), such as a guide wire, catheter shaft, or the like. A proximal sheath (22) is slidably extended over the inner member and is connected to the braided, electrically conductive member. The proximal sheath may be advanced distally to deform the braided member so that it defines a distally facing, ablative ring (40), and is operative to form an annular lesion.

Abstract: A medical device in one embodiment includes an electrode (12) which is connected to a flexible, tubular, movable member, such as a catheter shaft (14) or an outer sheath, which is slidably extended over a guide wire, flexible shaft, or other tubular member. A displacement mechanism is connected to the movable member, and may be actuated one or more times to displace the movable member in successive, predetermined increments, for creating a linear lesion or for performing diagnostic functions.
