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.
