Title: Guiding catheter system for ablating heart tissue

Abstract: A guiding catheter system for delivering an elongated therapeutic or diagnostic device into a patient's left ventricle which includes a first guiding catheter with a shaped distal extremity configured to be aligned with or parallel to a longitudinal axis or long dimension of the patient's left ventricle and a second guiding catheter slidably and rotatably disposed within an inner lumen of the first guiding catheter which has a shaped distal shaft section and an inner lumen configured to slidably receive an elongated therapeutic or diagnostic device such as a tissue ablation device, e.g. an optical fiber connected to a laser source, an ultrasonic energy emitting device or a radio frequency energy emitting device. The shaped distal section of the first guiding catheter is shaped or is shapable within the patient's heart chamber. The second guiding catheter is advanced out of the inner lumen of the first guiding catheter until the distal end extends out of the port in the distal end of the first guiding catheter and provides a passageway for the therapeutic or diagnostic device to engage the endocardium surface at a perpendicular or near perpendicular orientation.
