Abstract: An apparatus, including a light detecting means, determines the actual position of an optical fiber array having one or more, but fewer than all, short fibers by detecting light transmitted through the short fiber(s) as a laser beam is horizontally and/or vertically scanned across the proximal fiber end(s). The fiber array is attached to an alignment block that facilitates delivery of the array to an accurate positioning means comprising two substantially parallel dowels.

Abstract: The invention encompasses methods and flexible apparatus for creating fluid flow from one location to another through the repetitive expansion and collapse of bubbles generated as a result of the absorption of repetitive pulses of radiation in a fluid. This pumping phenomenon can be used to aid removal of a total or partial occlusion in a body passage by disrupting the surface of the occlusion with acoustic shock and pressure waves and/or by causing mechanical disruption of the occlusive material. Flexibility is improved with choice of materials and particular constructions.

Abstract: An apparatus and method for accurately and reproducibly locating a planar array of optical fibers in space are disclosed. A single acousto-optic modulator is used to accurately and substantially-simultaneously deflect multiple beams of different-wavelength radiation energy to each of said accurately-positioned optical fibers. Both aspects of the invention can be used in an apparatus and method for removing occlusions from vessels, as previously disclosed.
