This is a great idea. Well done and I am certain you have learned alot.
I would clarify the type of stent in your quiz. Also different manufactures use different materials.
There is a simulation of a stent going into a body and being assembled by one of our SolidWorks customers, Device Technologies. Play the video here

I would also look at Boston Scientific's animations they are very well done and list some of the materials they use.
