Apparatus and method of removing occlusions using ultrasonic medical device operating in a transverse mode
First Claim
1. An ultrasonic medical device for removing vascular occlusions comprising:
- a transducer capable of vibrating at an ultrasonic frequency, a probe engaging said transducer, said probe capable of translating the vibrations from said transducer and thereby vibrating transversely along its longitude thus creating a plurality of nodes of cavitation energy along at least a portion of a longitudinal axis of said probe,wherein said plurality of nodes of cavitation energy create an occlusion destroying effect along at least a portion of said longitudinal axis of said probe.

Abstract
A method for removing an occlusion is provided comprising introducing a transverse mode ultrasonic probe into a blood vessel, positioning the probe in proximity to the occlusion, and transmitting ultrasonic energy to the probe, until the occlusion is removed. The probe has a small cross-sectional lumen and is articulable for navigating in a tortuous vessel path. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion. The probe can also be used with a balloon catheter. The probe, sheaths, and catheter can be provided in a sharps container which further provides a means of affixing and detaching the probe from an ultrasonic medical device.
