  • Flexible flow apparatus and method for the disruption of occlusions
    Patent number: 6547779
    Abstract: Methods and apparatus for creating fluid flow from one location to another are disclosed. The fluid flow is created via the absorption of repetitive pulses of radiation in a fluid to generate bubbles that expand and collapse repetitively. This fluid mechanism, or pumping phenomenon, can be used to aid removal of a total or partial occlusion in a body passage by disrupting a surface of the occlusion with acoustic shock and pressure waves and/or by causing mechanical disruption of the occlusive material. Appropriate selection of materials and particular constructions improve apparatus flexibility.
    Type: Grant

  • Flexible flow apparatus and method for the disruption of occlusions
    Publication number: 20030065316
    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.
