Abstract

See full text

A guidewire with a cross section of at least a part of its length, comprising a filling material (PLM), a lumen (LM) arranged inside the filling material (PLM) for accommodating an optical fiber (OF) with optical shape sensing properties. One or more stiffening elements (RD) are arranged inside the first material (PLM), wherein the stiffening element(s) (RD) is formed by a material having a higher axial stiffness than the filling material. A braiding structure (BR) encircles all of: the filling material (PLM), the lumen (LM), and the stiffening element(s) (RD). Such guidewire can be designed with a circular symmetric bending behavior, and is thus suitable as an interventional medical device, e.g. for endovascular procedures, and still it can provide optical shape sensing properties.
