Guiding introducer system for use in the treatment of left ventricular tachycardia
First Claim
1. A guiding introducer system for use with an ablating catheter for the treatment of ventricular tachycardia in the left ventricle of the heart, comprising an inner and outer guiding introducer, wherein each contains a lumen running lengthwise therethrough, a proximal and a distal end, and wherein the outer guiding introducer is formed in a predetermined shape consistent with anatomy of the left ventricle, which shape assists in placement of the catheter in the left ventricle.
