US Patent 8647335 Laser applicator

A laser applicator has a catheter (12) that contains a optical fiber and a lateral decoupling area at the distal end. The end section of the strand is preformed to a loop (16) the plane of which runs crosswise to the main section (14) of the strand. This makes possible an extensive linear introduction of laser energy into the surrounding tissue. The invention is suited especially for the treatment of arrhythmia.
