Abstract
A guidewire made from a drawn-filled tube composite wire is described. The composite wire has a stainless steel outer sheath jacketing a nitinol core wire. The drawn-filled tube composite wire is ground at its distal end to expose the nitinol core, which has superelastic and kink resistant properties that are desirable for the distal end of a guidewire. The proximal end of the drawn-filled tube is not ground or if ground, the outer sheath of stainless steel is not removed to an extent sufficient to expose the nitinol core.
