  • Apparatus and method for using an ultrasonic probe to clear a vascular access device
    Publication number: 20030236539
    Abstract: The present invention provides an apparatus and a method for using an ultrasonic probe to remove an occlusion in vascular access devices including fistulas, grafts, catheters and subcutaneous access devices. The ultrasonic probe is inserted into the vascular access device and a section of a longitudinal axis of the ultrasonic probe engages the occlusion. A transducer transmits an ultrasonic energy from an ultrasonic energy source that produces a transverse ultrasonic vibration along the longitudinal axis of the ultrasonic probe. The transverse ultrasonic vibration of the ultrasonic probe provides a plurality of transverse anti-nodes along a portion of the longitudinal axis of the ultrasonic probe that cause a cavitation in a medium in communication with the ultrasonic probe to ablate the occlusion.
