Medical devices and methods for making and using the same. An example medical device may include an elongate core member having a proximal portion and a distal portion. A polymer jacket may be disposed about at least a portion of the core member. The jacket may include an outer surface. A lubricious coating may be disposed on the outer surface of the jacket. A coil may be disposed about at least a portion of the jacket. The coil may have an outer surface and may include a first section and a second section. At least a portion of the outer surface of the coil along the first section may be flush with or recessed below the outer surface of the polymer jacket. At least a portion of the outer surface of the coil along the second section may protrude from the outer surface of the polymer jacket, may be free of the coating, and may define a region of decreased lubricity.
