Title: SYSTEMS AND METHODS FOR RADIOMETRICALLY MEASURING TEMPERATURE DURING TISSUE ABLATION
Abstract:
The present invention provides systems and methods for radiometrically measuring temperature during ablation. Under one aspect, an interface module for use with an electrosurgical generator and an integrated catheter tip (ICT) that includes a radiometer, an ablative tip, an a thermocouple, may include a processor; a first input/output (I/O) port configured to receive a digital radiometer signal and a digital thermocouple signal from the ICT; a second I/O port configured to receive ablative energy from the electrosurgical generator; a temperature display; a patient relay in communication with the first I/O port, the second I/O port, and the processor; a non-transitory computer-readable medium storing operation parameters for the radiometer and for the thermocouple, and further storing instructions for causing the processor to execute the steps of: calculating a temperature adjacent to the ICT based on the digital radiometer signal, the digital thermocouple signal, and the operation parameters; causing the temperature display to display the calculated temperature; and closing the patient relay such that the patient relay passes ablative energy received on the second I/O port to the first I/O port.
