Abstract: Tissue ablation system that delivers independent therapies to multiple channels using a single radiofrequency power source through power time multiplexing. The system includes a radiofrequency generator having a controller that alternates power delivery between channels within defined time cycles. The controller determines power demands for each channel, calculates duty cycles for power delivery, and sets a common voltage amplitude based on the highest power requirements between channels. The system can operate in fixed time allocation mode where cycle time is evenly split between channels, or in dynamic allocation mode where duty cycles are adjusted to optimize voltage amplitude while maintaining required power delivery to each channel. The system enables independent therapy delivery through multiple channels while efficiently using a single power source.

Abstract: Systems and methods for improving temperature measurement accuracy in radiofrequency ablation systems while eliminating manufacturing calibration procedures. The systems include a radiofrequency generator with an analog-to-digital converter (ADC) that converts thermocouple analog voltage signals into digital converter voltage signals. The system determines thermocouple type, applies a first correction to digital converter voltage signals, applies a second correction to the converted cold junction voltage signals to compensate for sensor location offset, determines an adjusted voltage based on these corrected signals, and converts to a temperature using a standard lookup table corresponding to the thermocouple type. This approach eliminates individual device calibration during manufacturing while accommodating both T-type and K-type thermocouples, simplifying manufacturing and improving accuracy across different probe configurations.

Abstract: Systems and methods for intelligent power allocation in multichannel radiofrequency (RF) tissue ablation systems are described. The systems include a RF generator with limited power availability coupled to multiple RF probes forming separate channels. When total power demand exceeds generator capacity, the system implements power allocation policies to prevent therapy interruption. These policies include: prioritizing channels based on remaining treatment time, allocating power to channels with higher power demands, using impedance as a power demand predictor, and implementing power consumption thresholds. The controller determines power requirements for each channel and dynamically allocates available power according to the selected policy. This enables controlled treatment completion by intelligently managing limited power resources across multiple channels, avoiding unexpected therapy interruptions that could compromise surgical outcomes.
