Abstract

A laser ablation device which, an emitting double ring beam at the tip, is used in treatment, without permanent damage and scar, of natural diseases like venous insufficiency, of subsequently-formed diseases like fistula or of hemorrhoids formed as damaging of the vein. The device includes a fiber probe with two different conical angled surfaces where the rays guided through inside the fiber are reflected at the fiber tip via a first conical shaped-end formed at a first specific angle at the fiber's tip and a second conical shaped-end formed at different second specific angle by starting from a certain portion of the first conical shaped-end.
