Abstract
A fiber optic device for the transmission and lateral irradiation of laser energy, particularly for angioplasty, comprising at least one optical fiber (1), to the inlet end of which there is coupled a laser source (4) and to the outlet end of which, after removing its coating (3), there is applied a microcapsule (5) which is transparent to laser radiation and has a substantially toroidal thickened portion (6) surrounding said end and arranged to give rise to a "corolla-shaped" output laser beam.
