Abstract
The invention encompasses methods and apparatus for pumping fluid 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 emulsifying the occlusion with acoustic shock and pressure waves or by mechanically disrupting the occlusive material.
