Abstract
A hybrid tubular wire includes first and second elongate tubular bodies, fitted end to end, and about which a catheter may be threaded for guidance to a target location in a vasculature passageway of a body. The first elongate body has greater rotational stiffness than the second elongate body, which has greater lateral flexibility. Cuts are formed either by saw-cutting, laser cutting or etching at spaced-apart locations along the length of the second elongate body to increase its lateral flexibility. At least some of the cuts extend through the tubular body to the interior cavity to allow the escape of fluids flowing in the cavity.
