NON-METALLIC GUIDE WIRE

摘要

A guide wire having a non-metallic, non-woven core wire is disclosed. Monofilar, polymeric fibers of multifilar helically-wound non-metallic fibers are preferred core wire materials. The guide wire optionally includes further coatings and other materials on the core wire. In one embodiment, a non-metallic distal coil wire is disclosed. The guide wire of this invention is particularly useable for magnetic resonance imaging applications.

主权项

1. A core wire configured for use in a guide wire, the core wire comprising:
a) an axial length extending from a proximal core wire segment to a distal core wire segment, b) wherein the core wire comprises carbon or glass fibers held together by a binder resin, and c) wherein the distal core wire segment is provided with a series of radial cuts or etches, each cut or etch having a depth extending part-way through a thickness of the distal core wire segment.
