Guide wire and process for producing a core wire located in the guide wire

摘要

In the case of a guide wire, preferably for medical technology, comprising a core wire (1), which is surrounded by a hollow shaft of helically wound spring steel wire (2) or a sheath, it is proposed to apply around the guide wire a coating (3) of a smooth thermoplastic sleeve, produced by extrusion. Alternatively, it is proposed that the hollow shaft consists of PTFE and the core wire (1) consists of memory-alloy steel. <IMAGE>
