Stent Coating Failure Using Nano Scratch Testing
Drug–eluting stent coating is a novel approach in stent technology. It possesses a biodegradable and biocompatible polymer coating that releases medicine slowly and continuously at the local artery to inhibit intimal thickening and prevent the artery from being blocked againii. One of the major concerns is delamination of the polymer coating that carries the drug-eluting layer from the metal stent substrate. A reliable technique is in need to quantitatively measure the interfacial strength between the polymer coating and the metal substrate. The delicate structure and the small thickness of the stent mesh (comparable to a human hair) bring great challenge to the testing.
