May 14, 2012 — Biosense Webster Inc. launched the new Thermocool SF (surround flow) Nav irrigated ablation catheter with Curve Visualization in the United States during the Heart Rhythm Society (HRS) scientific sessions last week in Boston.
The new irrigated ablation catheter combines Biosense Webster’s latest porous tip technology with the accurate visualization of the Carto3 3-D mapping and ablation system. This enhanced technology is designed to reduce fluoroscopy exposure to physicians, lab staff and patients alike, enhance visualization of the ablation catheters orientation and improve procedural efficiency.
The Thermocool SF increased the number of irrigation holes in the tip from six to 56 offers more efficient, uniform cooling than previous catheters.
Curve Visualization allows better visualization of the catheter in the Carto3 system. Previously only the tip was shown during procedures. The new system shows 40-90 mm of catheter to better show the orientation of the catheter and how it is supported inside the heart.
“The Thermocool SF catheter with Curve Visualization provides substantial advantages over existing technologies,” said Daniel Melby, M.D., cardiac electrophysiologist from the Minneapolis Heart Institute in Minneapolis, Minn., was among the first to use the new technology in the United States. While using the Curve Visualization feature, the catheter position is more completely represented on the Carto display, thereby allowing less fluoroscopy use and easier catheter positioning on difficult atrial locations. In addition, the Thermocool SF platform provides the ability to consistently ablate at all atrial locations without the limitation of overheating and with 50 less volume delivery to the patient."
The catheter is approved in the United States for treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation when used with Carto systems and Type 1 atrial flutter for patients 18 years and older.
