Abstract
A catheter which has an elongated shaft having a layer of an ultra high molecular weight polyolefin, such as a melt-extruded ultra high molecular weight polyethylene (UHMWPE). The UHMWPE, forming at least in part a surface of the shaft, facilitates sliding a blood/contrast coated device along the shaft surface, and preferably substantially prevents or inhibits agglomerations of blood and contrast from adhering to the surface of the shaft in a patient's body lumen. In a presently preferred embodiment, the layer has a lubricious coating, such that the coated surface of the UHMWPE layer significantly decreases the force produced by the blood/contrast coated device sliding along the coated surface.
