Method and device for measuring ultrasonic activity in an ultrasound delivery system
First Claim
1. An improved therapeutic ultrasound delivery system comprising:
- a) an ultrasound signal generator for providing an ultrasound drive signal;
b) an ultrasound transducer receiving the ultrasound drive signal for converting the ultrasound drive signal into ultrasound vibration;
c) an ultrasound catheter, having proximal and distal ends, attached at the proximal end to the ultrasound transducer, for transmitting ultrasound vibration from the ultrasound transducer to effect treatment at a desired anatomical site; and
d) a device for measuring ultrasonic activity at the distal end of the catheter to verify proper operation of the ultrasound generator, the ultrasound transducer, and the catheter.

Abstract
A device for measuring ultrasonic activity in an ultrasound delivery system has a sensor for providing an output representative of a sensed ultrasound vibration level, an indicator for receiving the output of the sensor and providing an indication of the vibration level sensed thereby, and a rigid body to which the sensor is attached. The rigid body comprises a sensor attaching portion and a catheter abutting portion configured to abut the distal end of an ultrasound delivery system catheter. Ultrasonic activity of the ultrasound delivery system is measured by abutting the distal end of the catheter to the catheter abutting portion of the rigid body and noting the indication provided by the indicator. Use of a disposable sterile catheter abutting portion removeably attachable to the sensor attaching portion facilitates isolation of the sensor attaching portion within a bag along with an ultrasound transducer.
