Abstract
A device (10) for measuring ultrasonic activity in an ultrasound delivery system has a sensor (50) for providing an output representative of a sensed ultrasound vibration level, an indicator (14) for receiving the output of the sensor (50) and providing an indication of the vibration level sensed thereby, and a rigid body (16) to which the sensor is attached The rigid body (16) comprises a sensor attaching portion and a catheter abutting portion (18) configured to abut the distal end of an ultrasound delivery system catheter (20). Ultrasonic activity of the ultrasound delivery system is measured by abutting the distal end of the catheter (20) to the catheter abutting portion (18) of the rigid body (16) and noting the indication provided by the indicator (14). Use of a disposable sterile catheter abutting portion (18) removably attachable to the sensor attaching portion facilitates isolation of the sensor attaching portion within a bag along with an ultrasound transducer.
