Going with the Flow: New methods for Treating Cardiovascular Disease - Dr York Hsiang, University of British Columbia Vancouver

When an artery becomes blocked or damaged, a mechanical scaffold called a stent is often implanted into the vessel to improve blood flow. However, metallic stents can cause re-narrowing at the sites where they are implanted. This process is known as restenosis, which can lead to lethal complications. Dr York Hsiang, Professor of Surgery at the University of British Columbia, and his team use microengineering techniques to develop novel stents that can better detect restenosis, and treat it earlier when it occurs.
