    摘要: The present invention provides an apparatus and a method for an ultrasonic medical device having a flexible material engaging an ultrasonic probe. The flexible material surrounds a portion of a longitudinal axis of an ultrasonic probe of the ultrasonic medical device. The flexible material may extend beyond a probe tip. The flexible material cushions a tip of the ultrasonic probe and reduces the stresses on the ultrasonic probe as the ultrasonic probe is navigated within the vasculature. The ultrasonic probe may be shaped to increase a radial span of the ultrasonic medical device. In a preferred embodiment of the present invention, the flexible material comprises a polymer material. Additionally, the flexible material may have a high radiopacity.

    摘要: An apparatus and method for using an ultrasonic medical device to treat chronic total occlusions comprises an ultrasonic probe, a transducer, a coupling engaging a proximal end of the ultrasonic probe to a distal end of the transducer and an ultrasonic energy source engaged to the transducer. The ultrasonic probe is inserted into a vasculature and placed in communication with the chronic total occlusion. The ultrasonic energy source produces an ultrasonic energy that is transmitted to the transducer, where the transducer creates a transverse ultrasonic vibration along the ultrasonic probe. The transverse ultrasonic vibration creates a plurality of transverse nodes and a plurality of transverse anti-nodes along the longitudinal axis of the ultrasonic probe, creating cavitation along a portion of the longitudinal axis of the ultrasonic probe to ablate the chronic total occlusion.

    摘要: An apparatus and method for an ultrasonic medical device having an ultrasonic probe with a small proximal end to facilitate over the ultrasonic probe exchanges in a time efficient manner. The ultrasonic probe is inserted into a vasculature and moved to a treatment site of an occlusion. A coupling engaging the ultrasonic probe to a transducer is disengaged to expose a small diameter at the proximal end of the ultrasonic probe. A vascular intervention device is placed over the small diameter at the proximal end and moved along a longitudinal axis of the ultrasonic probe while the ultrasonic probe remains in an approximately fixed position in the vasculature. In a preferred embodiment, the ultrasonic probe acts a guidewire for over the ultrasonic probe exchanges of various vascular intervention devices.

    摘要: The present invention provides an apparatus and a method for an ultrasonic probe capable of bending, flexing and deflecting with the aid of a balloon to remove a biological material. An ultrasonic medical device includes a balloon catheter, a balloon that is supported by the balloon catheter, an inflation lumen located along a longitudinal axis of the balloon catheter and an ultrasonic probe located along an outside surface of the balloon catheter wherein the ultrasonic probe engages an outer surface of the balloon. The ultrasonic probe is inserted through at least one engaging mechanism on an outside surface of the balloon catheter. The inflated balloon causes the ultrasonic probe to bend, allowing the ultrasonic probe to move along a bend in a vasculature and increase a surface area of the ultrasonic probe in communication with the biological material for ablation.

    摘要: The present invention provides an apparatus and a method for an ultrasonic medical device operating in a torsional mode and a transverse mode. An ultrasonic probe of the ultrasonic medical device is placed in communication with a biological material. An ultrasonic energy source is activated to produce an electrical signal that drives a transducer to produce a torsional vibration of the ultrasonic probe. The torsional vibration produces a component of force in a transverse direction relative to a longitudinal axis of the ultrasonic probe, thereby exciting a transverse vibration along the longitudinal axis causing the ultrasonic probe to undergo both a torsional vibration and a transverse vibration. The torsional vibration and the transverse vibration cause cavitation in a medium surrounding the ultrasonic probe to ablate the biological material.
