Action initiates enrollment in TEMPASURE cardiac ablation catheter CE Mark clinical trial Advanced Cardiac Therapeutics, Inc . The TEMPASURE system is the world’s 1st RF cardiac ablation catheter to provide both saline irrigation and temperature-sensing technology. The system’s novel passive sensing microwave radiometry technology enables the electrophysiologist to measure the temperature of cardiac cells at three millimeters depth through the ablation procedure, providing real-time information that allows appropriate energy delivery and lesion control. ACT’s novel catheter program directly methods lesion creation through temperature, addressing a longstanding issue for physicians executing irrigated cardiac ablation, stated Karl-Heinz Kuck, M.D., head of the Section of Cardiology, St Georg Medical center, Germany, who’s co-principal investigator of the trial.
