| 1. A method for making a catheter sized for introduction into a body lumen, comprising:
providing a thin sleeve comprising an outer first surface and an inner second surface;
coating the first surface with a substantially uniform hydrophilic coating to impart the first surface with a predetermined
lubricity;
inverting the thin sleeve such that the first surface defines an inner surface of the inverted sleeve and the second surface
defines an outer surface of the inverted sleeve; and
attaching a tubular structure around the inverted sleeve, thereby providing a catheter comprising a lubricious inner surface.
