Abstract:
The invention features an acoustic medical device for making Doppler measurements and imaging within a body fluid conduit using a single-transducer. The device has an elongated device body, defining a device axis, constructed for positioning a distal end of the device body near a region of interest in the body fluid conduit. Disposed within the device body is an ultrasonic beam directing assembly that is constructed to direct a portion of ultrasonic energy from a single transducer in a direction for imaging within the body fluid conduit and to direct another portion of the ultrasonic energy in a direction for making Doppler measurements within the body fluid conduit.
