ABSTRACT:
An intravascular guidewire providing enhanced steerability and radioscopic visibility. The guidewire has an elongated selectively formable core and a plastic jacket including proximal and distal jacket portions, where the distal jacket portion is further divided into a proximal jacket section and a distal jacket section. The distal jacket portion incorporates means for enhancing the radiopaque properties of the distal jacket portion relative to the proximal jacket portion. The distal jacket section has a different radiopacity than the proximal jacket section, making the distal jacket section more easily viewable under radioscopy. One embodiment provides enhanced steerability with a distal jacket section made of softer material than the proximal jacket section. Another embodiment provides enhanced steerability with a distal jacket cross-section smaller than the proximal jacket cross-section.
