Systems for temperature-controlled ablation using radiometric feedback

摘要

The present invention provides systems and methods for temperature-controlled ablation using radiometric feedback. An interface module may include (a) a processor; (b) a first input/output (I/O) port to receive digital radiometer and digital thermocouple signals from an integrated catheter tip (ICT); (c) a second I/O port to receive ablative energy from a generator; (d) a temperature display; (e) a patient relay; (f) a computer-readable medium storing instructions for causing the processor to: (i) calculate a temperature adjacent to the ICT based on the digital radiometer and thermocouple signals and operation parameters; (ii) cause the temperature display to display the calculated temperature; and (iii) close the patient relay to pass ablative energy received on the second I/O port to the first I/O port; and (g) a temperature control subsystem to regulate the ablative power based on the calculated temperature.

主权项

1. An ablation system for regulating delivery of ablative energy to targeted tissue of a subject, comprising:
an ablation energy source configured to generate ablative energy to be delivered to targeted tissue of a subject via an ablation member of a catheter; a processor; wherein the processor is configured to calculate a temperature of the targeted tissue of the subject at a depth relative to a surface of the targeted tissue based on, at least in part, a signal generated by a radiometer at a tip of the catheter and a signal generated by a temperature-measurement device at the tip of the catheter; and wherein the system is configured to automatically regulate operation of the ablation member to deliver the ablative energy based upon at least the calculated temperature.
