St. Jude Medical announced that the FDA approved an ablation catheter system that the company says may reduce the duration of radiation exposure during procedures.

The agency gave thumbs up to St. Jude’s MediGuide-enabled ablation catheters used to treat patients with atrial flutter. The MediGuide technology allows a physician to visualize devices within the heart, including their location and orientation, by using a magnetic tracking system that locates sensors embedded in the devices. It allows physicians to navigate catheters in real-time on prerecorded fluoroscopy.

According to St. Paul, Minn.-based St. Jude, the recorded images are automatically adjusted to keep an accurate representation that compensates for cardiac motion, breathing and patient movement, which minimizes delays.
