ABSTRACT:
A guidewire or guiding element for vascular catheters, particularly balloon dilation catheters having an elongated core member with a tapered distal portion with a flexible length of interfitting links on the tapered distal portion. The individual links generally comprise a base with an aperture therein and a plurality of upwardly extending arms with the ends of the arms bent inwardly toward the longitudinal axis of the flexible length to engage the base of an adjacent link. Improved flexibility and torquability are provided by the flexible length of interfitting links.
