AFIB report: U.S. gets taste of magnetic catheter approach
Electrophysiologists liked what they saw at the AFIB Symposium when Stereotaxis highlighted its open-loop irrigated catheter that uses remote magnetic navigation.

The new catheter, which received FDA approval earlier this month, was co-developed by Biosense, a Johnson & Johnson company, and launched in Europe in November. The Niobe Magnetic Navigation System that drives the catheter was FDA-approved in 2004.

The irrigated catheter has been the gold-standard in the manual approach, and now it is available for a magnetic approach, which the U.S. electrophysiologists at AFIB were excited to utilize, said Rick Green, senior director of marketing at Sterotaxis, based in St. Louis, MO.

The irrigated tip provides cooling during radiofrequency ablation, which allows the device to stay in one place longer than without irrigation, Green told Cardiovascular Business News.

He said that EPs want to incorporate the Navistar RMT Thermocool irrigated tip catheter and the Coolflow Pump from Biosense Webster with the Stockert RF Generator. The catheter incorporates small irrigation holes at the tip to provide cooling during RF ablation.

Results reported at the meeting of the first 107 procedures performed at seven European institutions show a 90 percent acute success rate. About 68 percent of cases were to treat paroxysmal atrial fibrillation and there were no complications reported.

Biosense and Stereotaxis have alliances with both Siemens Medical Solutions and with Philips Healthcare for imaging systems, Green said.
