Test method description

A silicone thin wall (non-cylindrical) tube adapted to the device shape is developed, if required. The device is deployed in the silicone tube and a uniform pressure is applied around the tube. The defined device dimensions are measured at a defined pressure at any wished point. A 5 micron precision optical microscope is used to assess the device dimensional variations.
