Apparatus and method for an ultrasonic medical device having a probe with a small proximal end
First Claim
1. An ultrasonic medical device comprising:
- an ultrasonic probe having a proximal end, a distal end, and a longitudinal axis therebetween;
a transducer having a proximal end and a distal end, the transducer transmitting an ultrasonic energy to the ultrasonic probe; and
a coupling that engages the proximal end of the ultrasonic probe to the distal end of the transducer; and
an ultrasonic energy source engaged to the transducer that produces the ultrasonic energy, wherein the proximal end of the ultrasonic probe has a small diameter that allows a vascular intervention device to be placed over the proximal end of the ultrasonic probe and moved along the longitudinal axis of the ultrasonic probe while the ultrasonic probe remains within a vasculature of a body.

Abstract
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.
