I'm guessing
percutaneous coronary intervention is a phrase that is just casually thrown around in some medical fields, but it seems a pretty daunting introduction to me. The animation shows how balloons and stents - assumedly made of memory metal - are used to open a clogged artery.
It's a great explanation and illustration of a fairly complex process that would be nigh impossible to actually film from this same perspective.
Now I just need to get my hands on a stent to show in class.
