ST. LOUIS, Jan. 12 /PRNewswire-FirstCall/ -- Stereotaxis (Nasdaq: STXS) announced that the Celsius® RMT ThermoCool® catheter has been approved by the U.S. Food and Drug Administration for use with Stereotaxis' magnetic navigation system for the treatment of Type 1 atrial flutter. The product is the fifth advanced ablation catheter resulting from the on-going co-development agreement between Stereotaxis and Biosense Webster to design and distribute magnetically enabled catheters for mapping and ablation.
The Celsius® RMT ThermoCool® catheter was granted CE mark for distribution in the European Union in October 2009.
The Celsius® RMT and NaviStar® RMT catheters are the only magnetic catheters accurately matched to the navigational software of the Niobe™ Magnetic Navigation System for optimal performance and highly precise catheter manipulation.
With the Celsius® RMT ThermoCool® catheter, the family of magnetic irrigated ablation catheters offers localized and non-localized technology. Localized catheters are used for more complex arrhythmias requiring 3D electro-anatomic mapping for precise diagnosis, whereas non-localized catheters are typically used for a broader array of arrhythmias which can be treated using basic imaging and ECG recordings.
Separately, the FDA approved all of Biosense Webster's magnetic catheters for use with the magnetic field strength of 0.1 Tesla, an increase of 25 percent, which is now available in Stereotaxis navigation systems. In European clinical evaluations conducted in the fourth quarter of 2009, clinicians noted that the new field strength enhanced catheter navigation in difficult to reach locations; enhanced catheter stability, especially near the antrioventricular valves; and improved catheter contact along the isthmus region of both atria.
"The 25 percent improvement in field strength was immediately appreciated to improve navigation and stability for a wide range of procedure types with and without 3D mapping," said Dr. Tamas Szili-Torok, Clinical Head of Electrophysiology at Erasmus Medical Center in Rotterdam, The Netherlands. "We have implemented 0.1T as the default setting at our institution."
"These two new approvals provide clinicians in the U.S. with access to important new enhancements for magnetic navigation that we believe will enable clinical success in a broader range of arrhythmias," said Michael P. Kaminski, Stereotaxis President and CEO.
Stereotaxis designs, manufactures and markets an advanced cardiology instrument control system for use in a hospital's interventional surgical suite to enhance the treatment of coronary artery disease and arrhythmias. The Stereotaxis System is designed to enable physicians to complete more complex interventional procedures by providing image guided delivery of catheters and guidewires through the blood vessels and chambers of the heart to treatment sites. This is achieved using computer-controlled, externally applied magnetic fields that govern the motion of the working tip of the catheter or guidewire, resulting in improved navigation, shorter procedure time and reduced x-ray exposure. The core components of the Stereotaxis system have received regulatory clearance in the U.S., Europe and Canada.
