Featured Animation - Stent/Balloon Inflation

Animation shows stent/balloon inflation dynamics and the impact that this has on peak arterial stresses.  During inflation, the stent has a tendency to flare at the ends due to the balloon overhang.  Increased overhang results in increased stent endflare and peak arterial stresses.  This, in turn, can increase the chances of restenosis (uncontrolled cell growth leading to the artery clogging back up).  The model is currently being adjusted to test high-pressure and high-resistance lesions.
