With this test the length to diameter relationship of the stent, the unconstrained length of a self-expanding stent and the wall thickness of a stent is determined.

At EndoLab® foreshortening is measured using a high resolution microscope. The stents are dilated to minimum and maximum nominal diameter into high precision glass tubes.
