Radiofrequency Generator
Specialized equipment that produces controlled radiofrequency energy for catheter ablation. Provides precise power control and safety monitoring during ablation procedures.
Full Definition
A radiofrequency generator is a sophisticated medical device designed to produce controlled, high-frequency electrical energy (typically 300-750 kHz) for therapeutic tissue heating during catheter ablation procedures. Modern generators provide precise control over power output, temperature, and impedance monitoring, with integrated safety features including automatic power reduction or cessation when predetermined limits are exceeded. These systems typically offer multiple ablation modes, including power-controlled, temperature-controlled, and impedance-controlled delivery algorithms. Advanced generators incorporate features such as contact force integration, lesion size prediction algorithms, and real-time tissue assessment capabilities. The generator interfaces with specialized ablation catheters and may provide additional functions such as pacing, stimulation, and electrogram recording.
Usage
Usage note: Essential equipment in every EP lab. Often referred to simply as 'the generator' in clinical settings.
