ClosureRFG Radiofrequency Generator
System Overview
System Overview
The ClosureRFG radiofrequency generator supplies and controls the RF energy delivered
to the catheter. It measures and displays RF output power, load impedance (ClosureRFS
only), and elapsed time of RF delivery. The ClosureRFG generator also interfaces with a
sensor in the catheter to provide a continuous display of measured patient temperature
prior to and during RF delivery.
The major functional blocks of the ClosureRFG generator electronics are presented below.
