Abstract:
A catheter assembly, said catheter comprising an elongate tubular member having proximal and distal ends and an inner lumen extending between said ends, said member comprising:(a) a relatively stiff proximal segment comprising a material selected from the group consisting of polyethylene, polypropylene, Nylon, polyvinyl chloride, polyethylene terepthalate, polyester elastomer tubing, a polymer outer core with a metallic mesh inner core, and laminates thereof;(b) a relatively flexible distal segment; and(c) a transition section between said proximal and said distal segments that is less flexible than the distal segment but more flexible than the proximal segment,wherein at least the distal segment has been coated with a lubricious coating consisting essentially of a lubricity-causing polymer or oligomer comprising monomers of polysaccharides.
