Abstract
An improved retrograde coronary sinus perfusion catheter includes a flexible, tubular catheter body and an inflatable balloon. The catheter body has proximal and distal ends and an interior lumen. The inflatable balloon is located adjacent the distal end of the catheter body and has proximal and distal edges. The improvement includes an echogenicity enhancement embedded within the catheter body. The echogenicity enhancement is adapted to reflect ultrasonic waves at a characteristic different from the catheter body.
