Abstract
A catheter guidewire having a covering of a fluoropolymer tape. The tape may be applied either helically or longitudinally to the outer surface of the guidewire or to the surface of the wire from which the guidewire is made. Such a covering is inert, lubricious, flexible, will not flake, and can be applied as an extremely thin coating. Additionally, such a covering allows the guidewire to tolerate the application of greater force before uncoiling and wire breakage occurs. Other catheter guidewire devices having fluoropolymer tape coverings are also described.
