Abstract
A method of applying a magnetic medical device to the surface of an internal body structure, the medical device having a magnetically responsive element associated with its distal end, the method comprising applying a magnetic field to the distal end of the magnetic medical device to apply a measured and controlled force between the medical device and tissue to facilitate cardiac sensing, mapping, pacing, ablation, biopsying and other procedures. Contact is confirmed by the angle between the direction of the magnetic medical device and the applied magnetic field, and the contact force is controlled by controlling at least one of the magnetic field direction and the magnetic field strength.
