Abstract
The coated superelastic stent is formed from a tube of collagen having an inner structure of a micro-cable made of strands of a material exhibiting superelasticity or shape memory properties, such as nickel-titanium, and includes a strand of radiopaque material, such as platinum or gold, in order to provide a radiopaque marker during interventional therapeutic treatment or vascular surgery. The collagen tube can be loaded with a therapeutic agent for treatment of the desired site in the vasculature.
