Biosense Webster THERMOCOOL SF NAV Catheters Recall: Alert 402 May Cause Unintended
Biosense Webster recalls THERMOCOOL SF NAV catheters with specific model numbers due to Alert 402 causing potential unintended ablation areas during cardiac procedures.
Use caution until it’s fixed

Alert 402 implies a "Map: magnetic distortion" when connected to CARTO 3 System. This issue may subsequently lead the physician to ablate in an unintended area when delivering RF energy.
