MEDICAL BALLOON WITH RADIOPAQUE IDENTIFIER FOR PRECISELY IDENTIFYING THE WORKING SURFACE

摘要

A balloon catheter includes an elongated tubular shaft extending in a longitudinal direction said shaft having a proximal end and a distal end. An inflatable balloon is supported along the distal end of the shaft the balloon when inflated including first and second spaced conical end sections and a working surface between the conical sections. The balloon further includes at least one radiopaque marking identifying the transition from the conical end section to the working surface. Related aspects are also disclosed.
