Abstract
A catheter which may be configured as a loop during an ablation procedure, and a method of use for such a catheter, are disclosed. According to one aspect of the present invention, a method for medical treatment using an ablation catheter system that includes a catheter with a transmission line disposed within a flexible tubular member and a transducer that is located at a central portion of the catheter that is proximal to a distal tip portion of the catheter involves introducing the catheter into a first vessel of the body of a patient and past the heart of the patient such that the distal tip portion of the catheter at least partially passes out of the body through a second vessel while the central portion of the catheter is positioned within a cardiac chamber. Curvature, which includes the central portion of the catheter, is then formed in the catheter within the cardiac chamber, and electromagnetic energy is applied to the transmission line to cause ablation of cardiac tissue in a region adjacent to the central portion of the catheter. In one embodiment, a loop which includes the central portion of the catheter is formed within the cardiac chamber.
