Stereotaxis utilizes two magnets that generate a low level magnetic navigation field.  This magnetic field can be controlled by the physician to direct the movement of the ablation catheter.  This allows for fine control and increased stability when targeting cardiac tissue involved in a patient's abnormal heart rhythm. 

The standard approach to ablation procedures involves the use of manually operated catheters that must be relatively stiff to allow the physician to accurately steer to the appropriate location using x-ray guidance. The use of magnets to facilitate catheter movement allows for more precise control of catheter position. The Stereotaxis system has been integrated with standard X-ray as well as 3-D mapping technology to allow for real-time assessment of catheter position. As an added benefit, this technology can potentially reduce x-ray exposure for the patient and the physician. It also allows  for the use of catheters with soft tips, decreasing the risk of damage to vascular structures and the heart wall.  (see a video of the procedure)
