Apparatus and method for an ultrasonic probe device with rapid attachment and detachment means
First Claim
1. An ultrasonic medical device comprising:
- an ultrasonic probe having a proximal end, a distal end and a longitudinal axis between the proximal end and the distal end; and
a horn assembly having a distal end engaged to the proximal end of the ultrasonic probe through a coupling assembly, wherein the coupling assembly transmits an ultrasound energy from the horn assembly to the ultrasonic probe.

Abstract
An ultrasonic tissue ablation device comprising a transversely vibrating elongated probe, and a coupling assembly for probe attachment and detachment that enables the probe assembly and separation from the device body that includes the ultrasound energy source and a sound conductor, and a method of use for removal of vascular occlusions in blood vessels. The coupling assembly enables incorporation of elongated probes with small cross sectional lumens such as a catheter guidewires. The probe detachability allows insertion manipulation and withdrawal independently of the device body. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion. The horn assembly of the device that contains a sound conducting horn functions as an energy regulator and reservoir for the probe, and precludes loss of probe cavitation energy by its bending or damping within the blood vessel.
