Profile Effect / Flaring

Ensure the distal tip of crimped stent remains in contact with the balloon at all times, while navigating through a tortuous path. The degree of flaring of the stent away from the balloon is measured.

Test Procedure

Uses a contactless optical measurement system to measure the outside diameter of the stent and the outside diameter of the balloon, in a bent configuration. The measured gap between these measurements is the amount of flaring.
