These modules can handle and manipulate up to 50W of RF energy using feedback algorithms such as PID, Fuzzy logic, PWM or user developed mathematical algorithms for a single electrode of any type of catheters.  They also accept any type of temperature probes for monitoring the tissue temperature during ablation procedures. Up to 8 modules can be cascaded via a backplane for catheters with higher number of electrodes. They also can monitor physiological signals such as ECG during ablation procedures.  Figure1, RF Energy Management functional block diagram, figure 2, RF Energy management Module assembly, figure 3, single backplane board and figure 4 cascaded multiple modules backplanes.
