Abstract
A catheter assembly for dilation of constricted blood vessels includes a catheter supporting a radiopaque balloon insertable into a patient blood vessel. The catheter provides a coupling passage between the inflatable radiopaque balloon and a three-way valve. The three-way valve is selectively coupled to a liquid feed mechanism such as a conventional syringe and an expandable pressure buffering balloon. The communication between the expandable radiopaque balloon and the liquid feed mechanism or pressure buffering balloon is controlled by switching the three-way valve.
