Stents are a wonderful creation of modern medical engineering that aid physicians and surgeons in the treatment of heart disease. Conditions, such as smoking, diabetes, and high cholesterol help promote atherosclerosis, the build up of fatty plaque within arteries, which can ultimately lead to heart attack and stroke.

With stringent requirements from regulations, manufacturers must demonstrate that they have considered risks of device failure and satisfactorily mitigated against them. Mechanical testing of stent and stent materials is performed in vitro to aide designers and researchers in gathering performance data ahead of device approval and clinical use.
The stent is used to open arterial paths that may be occluded by plaque. Upon placement of the stent, dislodged plaque (or embolic material) can potentially be responsible for heart attacks, strokes, kidney failure, or death. ... Subscribe to Instron News!
