| 摘要 |
A medical device, such as a vascular catheter, is at least partly made from a formulation which comprises a relatively soft polymer, a compatible, relatively stiff polymer, and up to about 15 weight percent of a fluorine-containing polymer, to provide a material which has inherent lubricating characteristics against, for example, a guidewire in a guidewire lumen of the catheter. In one embodiment, the tip of the catheter may be made of such a fluorinated formulation, while the catheter body may be fluorine-free.
