Systems and methods for radiometrically measuring temperature during tissue ablation

An ablation system for facilitating delivery of ablative energy to targeted tissue of a subject, comprising:

• a catheter comprising a proximal end and a distal end;
• a catheter tip located along the distal end of the catheter, the catheter tip comprising an ablation member, a radiometer and a temperature-measurement device, the temperature-measurement device being configured to detect a temperature along the catheter tip;
• wherein, when electrically activated, the ablation member is configured to emit energy to the targeted tissue of the subject;
• and
• wherein the system is configured to communicate with a processor that based on, at least, a signal generated by the radiometer and a signal generated by the temperature-measurement device, calculates a temperature of the targeted tissue of the subject at a depth relative to a surface of the targeted tissue.

An ablation system for facilitating delivery of ablative energy to targeted tissue of a subject, comprising:

• a catheter, wherein the catheter comprises an ablation member and a temperature-measuring device configured to detect a temperature along a portion of the catheter;
• and
• a radiometer;
• wherein the ablation member is configured to emit energy to the targeted tissue of the subject, when activated;
• wherein the system is configured to communicate with a processor that based on, at least, a signal generated by the radiometer and a signal generated by the temperature-measuring device, calculates a temperature of the targeted tissue of the subject at a depth relative to a surface of the targeted tissue.
