Zusammenfassung: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.
