ABSTRACT:
A guidewire for insertion into the vascular system of a patient, to provide a path of advancement for an atherectomy catheter which surrounds the guidewire as it advances. The guidewire has an intermediate portion positioned proximally of the distal tip, which intermediate portion defines a transversely enlarged portion of a size to prevent substantial distal advancement of the atherectomy catheter or other catheter that surrounds the guidewire. Particularly, this protects the distal tip portion of the guidewire from engagement with moving blades of an atherectomy catheter.
