Abstract
The catheter is constructred of a substantially cylindrical tube, longitudinally subdivided in multiple parallel lumens for wires, available to introduce drives having a distal end with a variable curving, and of fiberoptics for the delivery of energy as laser emission, or different ablation devices. The amagnetic distal electrodes permit the high-resolution mapping of multiple monophasic action potentials just at the arrthythmogenic foci themselves, the magneto cardiographic localization of the catheter and the possible modification of the electrophysiological substrate with the delivery of energy as laser emission. The catheter can be intracardiacally manipulated in the patient with a very high accuracy by exploiting the variability of the curving of the distal end and the sliding thereof into preformed external sheaths, for fitting at the best the threedimensional coordinates thereof with those of the arrhythmogenic substrate, non-invasively predetermined by magnetocardiographic imaging.
