ABSTRACT:
An improved valve for use in angioplasty comprising a cup shaped body having a piston adapted to slide into a first and second position therein. A passage and a plurality of chambers and openings are formed within the piston. The piston is biased in a first position to align openings and a passage for fluid to flow through a chamber and a one-way valve to inflate a balloon catheter. When the piston is forced into a second position, openings are aligned to permit fluid to flow from the balloon catheter into a chamber through a second one-way valve to rapidly deflat the balloon catheter. A balloon catheter can thereby be quickly deflated easily by a physician.
