Advanced Cardiac Therapeutics initiates first-in-man CE mark trial to study new catheter system


The first patients have been enrolled in a first-in-man CE mark clinical trial of the safety and performance of the Tempasure cardiac ablation catheter. The Tempasure system (Advanced Cardiac Therapeutics) is the world’s first radiofrequency cardiac ablation catheter to offer both saline irrigation and temperature-sensing technology.

The Tempasure system is designed to result in better outcomes for patients by reducing overall procedure time and increasing therapeutic effectiveness, while avoiding rare but serious adverse events. The system’s novel passive sensing microwave radiometry technology allows the electrophysiologist to measure the temperature of cardiac tissue at three millimeters depth during the ablation procedure, providing real-time information that enables proper energy delivery and lesion control.

“Advanced Cardiac Therapeutics’ novel catheter system directly measures lesion creation through temperature, addressing a longstanding problem for physicians performing irrigated cardiac ablation,” said Karl-Heinz Kuck, head of the Department of Cardiology, St Georg Hospital, Germany, who is co-principal investigator of the trial. “I am very excited about the promise of this new technology to increase the safety and success of cardiac ablation procedures.”

“I found the Advanced Cardiac Therapeutics system straightforward to use, requiring no different handling or training,” said Yves Vandekerckhove, chairman of the Department of Cardiology at Sint Jan Hospital, Bruges, Belgium, who performed the first-ever procedure with the system. “Even in the first few patients, we were able to see clinical therapeutic outcomes that closely matched the temperature measurements. The patients I have treated are doing very well.”

“Many years ago, the addition of a thermocouple enabled precise temperature control and temperature mode energy delivery to standard radiofrequency catheters. In a similar way, this microwave radiometry technology promises to significantly advance the way we perform irrigated radiofrequency ablations for patients with cardiac arrhythmias,” said Pedro Brugada, professor of Cardiology, chairman and scientific director, Cardiovascular Division, UZ Brussel, Brussels, Belgium, and study’s co-principal investigator.

The prospective, multicentre, single arm study will enrol up to 30 patients with atrial flutter in Europe and New Zealand. Patients enrolled in the trial will be studied during ablation, with follow up at seven and 30 days. Operators are blinded to the microwave radiometer signal in the trial procedures, using Advanced Cardiac Therapeutics’ catheter in exactly the same way as for current irrigated procedures.

“The initiation of our first-in-man study marks a major milestone for Advanced Cardiac Therapeutics,” said Peter van der Sluis, the company’s CEO. “We are very excited to soon launch the Tempasure temperature-sensing ablation catheter.”

Kenneth Carr, pioneer of the microwave radiometry technology, commented, “It is incredibly exciting to see my life’s work proceed to clinical use and directly benefit patients with cardiac arrhythmias.”

About the Tempasure cardiac ablation catheter

The Tempasure cardiac ablation catheter continuously measures temperature at three millimeters depth below the heart wall surface using Veritas technology, a proprietary microwave radiometry system. The Tempasure system is designed to improve patient outcomes by providing electrophysiologists with real-time validation information and greater control in lesion creation.
