Abstract
A catheter assembly having a balloon integrated at its distal tip. The balloon, while inflated, prevents the back-flow of fluid introduced through the catheter assembly into vessels or ducts in a mammalian subject. The catheter has an inner lumen and a coaxial outer lumen. An inflatable member attached at the distal end of the catheter forms the balloon. The outer lumen provides the channel for inflating the balloon and the inner lumen provides the channel for a guide wire or for use in delivery of fluids or particles. This low profile balloon catheter design allows for high maneuverability and also facilitates the manufacture of small diameter balloon catheters.
