Abstract
A system and method for efficient delivery of radio frequency (RF) energy includes a backplane. At least a single channel card is removably coupled to the backplane for controlling the amount of RF power delivered through a single channel via an electrical coupling to at least one ablation electrode or a catheter. The at least one channel card provides a gradual increase in RF power calculated in real-time during an initial ramp-up phase, and to limit the delivery of RF power through the electrical coupling based on a received temperature of cardiac tissue in contact with the at least one ablation electrode, thereby reducing the likelihood coagulum formation.
