Abstract
Apparatus for pumping fluid from one location to another via generation of bubbles in fluid, and expansion and callapse thereof, are described. These apparatus deliver repetitive pulses of radiation to a fluid to form bubbles therein. The expansion and collapse of the bubbles cause fluid motion or pumping. This pumping can be used to facilitate removal of a total or partial occlusion in a body passage by a variety of mechanisms. The apparatus are flexible to facilitate use within a body passage.
