Abstract
An intravascular catheter having an elongate shaft that is entirely non-magnetically responsive and at least partially radiopaque, including a reinforcement layer. The reinforcement layer may comprise a non-magnetically responsive radiopaque metal, such as a multi-strand Tungsten braid. The improved shaft of the present invention is compatible with x-ray and MRI visualization techniques, and may be incorporated into a wide variety of intravascular catheters such as guide catheters, diagnostic catheters, balloon catheters, etc.
