Stent Flow Visualization

By looking at the flow through a stent, a better understanding of the reasons for restenosis can be understood. We were hired to evaluate a new type of stent under development and compare it to the market leader. Below is photograph of the market leader in a transparent silicone rubber artery. The inset picture shows what portion of the stent is being visualized. The flow is seeded with fluorescent particles and illuminated by laser sheet light. View video ( 1 MB)

These type of videos can be valuable when proving the efficacy of a medical device to the FDA.
