ABSTRACT:
A fiber-optic probe for soft-tissue laser surgery such as angioplasty comprising a section of an optical fiber having a beam-inlet end (23) and a beam-outlet end (22) and composed of a beam-propagating core (18) and a cladding (19) a part of which is removed in the form of openings (20, 21) through which a portion of the laser beam leaves the fiber-optic probe and is directed laterally to the longitudinal axis 34 of the fiber to the operation site. The intensity distribution of the outgoing beam can be controlled by selecting a required pattern of distribution of the openings.
