DEVICE FOR TREATING CARDIAC ARRHYTHMIA BY HEATING OR COOLING

摘要

A device for the treatment of cardiac arrhythmias (7) which detects the occurrence of an arrhythmia and modifies the temperature of endocardial tissue without causing permanent damage to the tissue site. The device contains a thermal catheter (2) inserted into the heart (1) comprising a sensor electrode (5, 6) and a means for adjusting temperature at the distal end of the catheter. The thermal catheter may either cool or heat the tissue and the device may have a means for drug infusion.
