    Abstract: An endocardial mapping and ablation system (11) includes a catheter probe (12) comprised of a plurality of flexible longitudinally extending circumferentially spaced apart arms (23). Electrodes (21) are carried by the arms and are adapted to be moved into engagement with the wall of the heart. Markers (66) visibly ultrasonically are carried by the arms for encoding the arms from another. An ablation catheter (13) is carried by and is slidably mounted in probe (12) and has a distal extremity movable into the heart while the probe is disposed therein. An ablation electrode (86) and ultrasonic viewing means (41) are carried by the distal extremity of the ablation catheter. The distal extremity of the ablation catheter is movable into positions to view ultrasonically the markers carried by the arms of the catheter probe so that the arms can be identified and the spacing of the arms can be ascertained.

    Abstract: In a shapable catheter and method for positioning a shapable catheter within a body cavity, a core wire is provided which includes a pre-shaped region bent into a predetermined shape. A catheter is provided which includes a lumen proportioned to slidably receive the core wire. The catheter includes a rigid proximal section and a flexible distal section. During use, the distal end of the catheter is inserted through a patient's vasculature and is passed into a body cavity. The pre-shaped region of the core wire is passed into the lumen and is straightened by the rigid proximal section of the catheter. The pre-shaped region is passed further into the catheter until it reaches the flexible distal region, in which the pre-shaped section re-assumes its predetermined shape and causes the core wire to form the distal section of the catheter into the predetermined shape. The distal section of the catheter is positioned in contact with tissue in the body cavity, and electrodes carried by the distal end are used to map and/or ablate the tissue.

    Abstract: An endocardial mapping catheter (10) includes an actuator assembly (14) and an elongated hollow support sheath (12) which extends from the actuator assembly (14). A plurality of electrical probes (18 a-h) are slidingly disposed for independent movement through the sheath (12), and each probe (18) is attached to the actuator assembly (14) for individual manipulation. A guide (16) is mounted on the end of the sheath (12) opposite the actuator assembly (14), to radially deploy each electrical probe (18) along a separate favorable trajectory as the probe is manipulated. In operation, the probes (18) are initially retracted into the sheath (12). Once the guide (16) is positioned as desired, all of the probes (18) are individually deployed until they have each made contact with the endocardium of the left ventricle. Timed responses are obtained from the probes (18), and a series of such responses from various guide locations in the left ventricle are recorded to accomplish circumferential endocardial mapping of the heart.
