Fiber
delivery of laser energy has no MR compatibility issues and is used with MR
guidance in the field. But, it is not widely used as the cure of Atrial
Fibrillation, since there is risk of perforating the myocardial wall. Several
diffusing tip designs to emit light in cylindrical symmetry exist, but, due
to their orientation with respect to the cardiac chamber, common RF delivery
methods cannot be applied directly. In
our study, we propose a novel multiple fiber laser energy delivery with
catheter approach and a system that imitates the scars created with RF probes
under MR guidance.
