Abstract

A medical device for partial insertion into a patient and navigating passageways, channels, canals, cavities, and other interior parts of said patient, said medical device comprising an elongate body having an in-the-body segment which, in normal use, is inserted in the body of a patient. At least a portion of the in-the-body segment is provided with a lubricious coating. The coating displays a gradient of lubricity along the length of thereof.
