US Patent 8007674 Method and devices for preventing restenosis in cardiovascular stents

Described herein are devices and methods fabricating devices having nanostructures that allow adhesion or growth of one cell type, such as endothelial cells, more than another cell type, such as smooth muscle cells. In particular, stent covers having such nanostructures are described, and methods for fabricating these stent covers. Also described herein are methods for optimizing the nanostructures forming the devices.
