Rapid Inflation/Deflation Compared With Prolonged High-Pressure Balloon Inflation

Prolonged inflation will be performed at high pressure(16 atm)and maintained for 30 sec with \<0.3 atm drop during that period.

The rapid inflation method will consist of reaching an operator determined high-pressure (16 atm) with the stent-deployment balloon and maintaining it the duration of time determined by the operator but \<30 sec if the balloon is fully inflated and longer only if the balloon requires a longer duration to become fully inflated.
