Abstract
A coaxial cable apparatus which transmits radio frequency (RF) energy for the ablation of biological tissues has inner and outer coaxial conductors extending substantially the entire length of the cable from a proximal end portion to a distal end portion. An RF antenna is disposed at the distal end portion of the cable and transmits RF energy for ablation of a tissue region to be treated. An angioplasty balloon is disposed over the RF antenna and communicates with a fluid supply and extraction passageway extending through the cable to allow the balloon to be inflated for an angioplasty procedure including tissue ablation, and to be deflated after the procedure is complete.
