Magnetic Navigation System (MNS) is a rapidly growing technology with nearly 100 systems globally installed. It was first utilized in the field of neurosurgery and cardiac electrophysiology and is now being extended to percutaneous coronary interventions (PCI). Once the tip direction is aligned in the desired direction then the wire can be manually advanced until another change of direction is required. This basic principle of wire guidance is retained in the newer generation wires and towards the development of a radiofrequency (RF) enabled magnetic wire aimed at coronary and peripheral occlusion. The development of the magnetically enabled RF ablating wire together with the recent upgrades in MSCT co-integration software has brought the MNS closer to realizing its full potential to the chronic total occlusions (CTOs) field.
