Abstract
An ultrasound imaging balloon catheter for imaging near a wall of a cavity or passageway. The apparatus includes an elongated catheter having a primary lumen with a distal opening enveloped by the balloon. A pre-shaped ultrasound catheter carrying ultrasound transducer elements can be advanced through the catheter and inserted into the inflated balloon. The shape of the distal portion of the ultrasound catheter positions the ultrasound transducer elements radially outwardly of the catheter lumen, and preferably adjacent to the wall of the balloon, thus centering the image close to the wall of the cavity or passageway, giving greater depth of image at the portion of the wall of interest.
