Abstract
A device and method to improve the ultrasound visibility of a catheter placed inside the body is described. The catheter is sonically vibrated by an external driver device that transmits the acoustic vibration down the catheter and inside the body. An ultrasound transducer is used to pick up the ultrasound vibrations directly or detects the sonic vibrations using a Doppler mode ultrasound machine.
