  • Occlusion device
    Patent number: 6689098
    Abstract: An occlusion device for occluding a body conduit including an elongate tubular shaft having an inflatable balloon disposed near the elongate shaft distal end and a proximal seal having a sufficiently small profile to allow a second catheter to pass over the distal occlusion device while the inflatable balloon remains uninflated. One occlusion device includes an elongate fluid displacement rod within the occlusion device elongate shaft, providing both a fluid pressure source and a seal. The elongate rod can be rapidly advanced and retracted, providing rapid and controlled inflation and deflation of the distal balloon. Also provided are alignment devices for aligning inflation fluid sources with occlusion device tubular proximal ends which can inject fluid through the device into the distal balloon.
    Type: Grant
    Filed: October 25, 2002
    Date of Patent: February 10, 2004
    Assignee: SciMed Life Systems, Inc.
