Abstract
A microwave ablation system and method is disclosed comprising a balloon catheter apparatus and a control system. The balloon catheter apparatus comprises a catheter configured to house a coaxial cable and one or more coolant channels, an inflatable balloon located at the distal end of the catheter, and an antenna positioned in the inflatable balloon and in communication with the coaxial cable. The control system comprises a fluid pump configured to introduce fluid into a proximal end of the catheter, a power amplifier capable of generating microwave energy for delivery to the target tissue zone for at least one energy application cycle ranging from 60 seconds to 600 seconds at a frequency ranging from 2.4 GHz to 2.5 GHz, and a computer system configured to monitor and/or regulate the delivery of microwave energy to the target tissue, the fluid pump, at least one sensor, and antenna reflected power.
