I think I've found it :-)

Anything to do with this ??

The proprietary Stereotaxis Magnetic Navigation System is designed to allow physicians to more effectively navigate catheters, guidewires and other magnetic interventional devices, both our own and those we are co-developing with strategic partners, through the blood vessels and chambers of the heart to treatment sites and then to effect treatment. This is achieved using computer-controlled, externally applied magnetic fields that precisely and directly govern the motion of the internal working tip of the catheter, guidewire or other magnetic interventional devices

OH. obviously not,

Never mind, that was a very helpful link!
