Embodiments described herein relate to methods of using a catheter having a braided conductive member. One embodiment relates to a method for treating a condition of a patient that involves contacting an exterior wall of a blood vessel with the braided conductive member. Another embodiment relates to a method that involves contacting a wall of a blood vessel with the braided conductive member and controlling energy delivery to the braided conductive member based on at least one sensed temperature.

Methods of using a catheter having a braided conductive member

An electrophysiology catheter and method of use for mapping and ablation procedures. The catheter includes a braided conductive member at its distal end that can be radially expanded. The catheter can be used in endocardial and epicardial mapping and ablation procedures.

Apparatus and methods for mapping and ablation in electrophysiology procedures

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

Method and apparatus for performing cardiac ablations

A medical device in one embodiment includes an electrode which is connected to a flexible, tubular, movable member, such as a catheter shaft 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.

Medical device having an incrementally displaceable electrode

A medical device is disclosed which includes a deformable electrode device. 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, such as a guide wire, catheter shaft, or the like. A proximal sheath 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, and is operative to form an annular lesion.

Apparatus for creating a continuous annular lesion

A catheter for ablating and/or mapping tissue on the inner wall of a blood vessel, including a body portion and a tip portion having a proximal section and a distal section, the proximal section including a proximal ablation electrode and a proximal mapping electrode and the distal section including a distal ablation electrode and a distal mapping electrode, 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.
