The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.

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.
