Angioplasty pressure-volume measurement.
An instrument has been developed for controlled inflation and deflation of an angioplasty balloon. The mean difference between inflation to 800 kPa in air and a simulated coronary artery is 71.2 kPa. The repeatability of four inflation/deflation cycles is 6.4 kPa with the balloon in air and 9.0 kPa in the simulated artery.
