FIELD: medicine.
SUBSTANCE: invention relates to medical equipment and aims at real-time optic pyrometer-based tissue temperature monitoring. A catheter comprises a catheter body, a distal section of a tip which includes an ablation electrode accommodating a shell and a stopper forming a cavity, and an optical fibre passing through a cavity a distal end of which is placed in a hole of the ablation electrode shell. An optic fibre provides detection of black body radiation during ablation tissue removal. The catheter is a part of systems for the detection of black-body radiation during ablation tissue removal, and for ablation removal and tissue temperature measurement. The catheter for ablation cardiac tissue removal also comprises a deflectable portion distal to the catheter body, a tip section with the electrode for RF ablation cardiac tissue removal, and an optic collector for the detection of black body radiation from cardiac tissue. This catheter is a part of the system for cardiac tissue removal and tissue temperature measurement which also contains the system of the detection of optic emission coupled with the optic collector for processing signals representing the wavelength of at least a part of black-body radiation to determine tissue temperature.
EFFECT: use of the invention enables real-time tissue temperature monitoring during the injury removal procedure to avoid the critical temperature threshold.
