ULTRASONIC IMAGING DEVICES AND METHODS OF FABRICATION

摘要

An ultrasound catheter suitable for insertion in the body lumens of a patient during medical procedures is provided. An ultrasound transducer may be provided at the distal tip of the catheter. An inflatable balloon may be provided at the distal end of the catheter on the proximal side of the ultrasound transducer. The catheter may have lumens for inflation fluid, electrical wires,and a guide wire. A sheath that runs through the balloon may be used to isolate the electrical wires and guide wire from inflation fluid in the interior of the balloon.
