Forces on cardiac implantable electronic devices during remote magnetic navigation

Abstract

Exposure of pacemakers or implantable cardioverter-defibrillators to a magnetic field of 0.1 T does not result in a force exceeding the regulatory demanded 5 N that could damage the connected leads.

The Effects of Catheter Ablation on Permanent Pacemakers and Implantable Cardiac Defibrillators

“…[15][16][17] In the case of subcutaneous defibrillators, to date there have been no reports of significant interactions with catheter ablation, though its use in the United States is rapidly increasing. 18 Since the pulse generator and lead system are entirely subcutaneous, the anticipated potential interaction is EMI.…”

A novel remote-controlled robotic system for cerebrovascular intervention

“…By controlling the magnitude of the current to heat the springs, different degrees of deformation are achieved, which produces different levels of force to control the tip in order to bend it at different angles for passage through the blood vessel branches. STEREOTAX developed the Niobe ® magnetic navigation system. The system uses magnetic force: two permanent magnets are located on opposite sides of the patient table to provide the driving force.…”
