INTERVENTIONAL GUIDEWIRE

摘要

The present invention is an interventional guidewire particularly adapted for use in percutaneous transluminal angioplasty (PTA) procedures. A guidewire of this invention enhances peripheral vascular access for either diagnostic or therapeutic vascular or arterial procedures by having opposing ends of different stiffnesses. Retrograde dorsalis pedis artery access to upper body vascular occlusions is a particularly preferred application of this invention.
