Medical Implants: Enabling Angioplasty‐Ready “Smart” Stents to Detect In‐Stent Restenosis and Occlusion (Adv. Sci. 5/2018)

Stents are implanted in occluded arteries to restore blood flow thus saving millions of lives world‐wide, although the most common complication known as restenosis, re‐narrowing of arteries, remains as a critical risk to stented patients. In article number https://doi.org/10.1002/advs.201700560, Kenichi Takahata and co‐workers demonstrate a smart stent that monitors hemodynamic change and wirelessly transmits the data for early detection of restenosis. This breakthrough device, with robust electromechanical design, proves compatibility with the present interventional procedure, advancing smart stent technology towards a clinical reality.
