Abstract
A surgical guidewire having a distal section and a proximal section includes a core with a first end and a second end. A longitudinal spring disposed circumferentially of the core has a first end coupled to the second end of the core and a second end which extends distally of the core. A sheath has a spaced sliding relationship with at least a portion of the spring and a frictional fixed relationship with at least a portion of the core. An associated method of manufacture includes the step of selecting from a group of sheaths having different characteristics but a common inside diameter, a particular sheath desired for the guidewire.
