Low friction profiles for medical devices

A medical device, comprising:

• an elongate shaft extending from a proximal end to a distal end;
• a coil disposed about a distal end region of the elongate shaft;
• an atraumatic tip secured to a distal end of the coil and the distal end of the elongate shaft, and
• wherein the elongate shaft includes a plurality of helically extending grooves and a plurality of helically extending ridges formed in an outer surface thereof and extending between the proximal end of the elongate shaft and a proximal end of the coil.
