This invention discloses an ablation catheter system with fixation means for use in treatment of cardiac tissues and in other medical applications, such as ablating tumors in a natural body conduit or cavity by applying RF energy, and an inner catheter having alternate energy sources for enhanced ablation. The catheter system passes through a natural body opening to reach the target tissue, where the catheter system stays in a desired position via its fixation means and delivers therapeutic energy selected from the group of laser energy, microwave, inductive radiofrequency and ultrasonic energy to the target tissue for improved treatment.
