Hansen Medical has initiated a study to evaluate its flexible catheter Sensei X robotic system in patients with ventricular tachycardia.

The Sensei robotic system features a flexible catheter with remotely steerable distal tips, designed to simplify and enhance catheter navigation and therapeutic intervention.

The two-year, follow-up study, named ERASE-VT, is being sponsored by Imperial College of Science Technology and Medicine out of the Cardiology Department at St. Mary's Hospital, London. Up to 200 patients with implantable defibrillators will be enrolled at up to eight sites in Europe.

The primary endpoint of the study is to reduce or eliminate episodes of ventricular tachycardia, while the secondary endpoints include evaluating the effects of robotic ablation on patient hospital length of stay, mortality and quality of life.

St. Mary's Hospital electrophysiologist Prapa Kanagaratnam said "Our unit has already demonstrated the ability of the flexible catheter Sensei X robotic system to improve radiofrequency lesion quality through greater catheter stability and precision compared to the conventional manual approach."

Hansen Medical president and CEO Bruce Barclay said based on the early clinical feedback, the company believes that its flexible robotics have the potential to provide benefits not available with conventional manual catheter ablation.
