Title: Micro-strand cable with enhanced radiopacity

Abstract: This invention relates generally to emplacable devices for interventional therapeutic treatment or vascular surgery, and more particularly concerns a stranded micro-cable with enhanced radiopacity that can be used to fabricate a vascular device, a stent, a guidewire or the like. The micro-cable is made of strands of a material exhibiting super-elasticity 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 micro-cable can be used to form occluding coils which can be used in devices to restrict, reinforce, or to occlude areas of small diameter vasculature such as an aneurysm or malformation in an artery or vein in the brain.
