Pressurized Internal Diameter

Determination of internal diameter under simulated physiological conditions of the same order of magnitude as the arterial blood pressure: 120 mmHg.

Test Procedure

Samples are extended to their functional length.  Specified pressure is applied uniformly to the inside of a prosthesis which is extended to its usable length.  A cylindrical balloon mounted over a cylindrical mandrel is used.  An optical measurement system is used to measure external diameter.
