This is a large medical device developed using the most advanced technology which allows remote control under the guidance of an external magnetic field to avoid cardiac perforation and other serious operative complications, avoid arbitrary manipulation of the catheter, and allow remote operation of X-ray radiation. The entire computer control improves work efficiency, increases physician safety, and reduces the probability of human error. Remote magnetic navigation is a technique well suited to the treatment of complex arrhythmias, on account of its efficacy and reliability.
