Guide wire for minimally invasive operations and method for producing a guide wire

A method for producing a guidewire for minimally invasive interventions, comprising:

• adjoining a distal wire endpiece to a wire main piece, wherein the distal wire endpiece includes a first inner shaft having a first fiber composite material;
• and
• providing, in the first inner shaft of the distal wire endpiece, a plurality of weakened sites generated by mechanical interventions, wherein the mechanical interventions include at least one of:
• buckling loads, bending loads, or breaking loads.

A guidewire device for minimally invasive interventions, the guidewire device comprising:

• a wire main piece;
• and
• a distal wire endpiece adjoining the wire main piece, wherein:
• the distal wire endpiece includes an inner shaft and at least one protective layer enveloping the inner shaft,
• the inner shaft includes:
• a first fiber composite material,
• a plurality of weakened sites that are generated by mechanical interventions, a core, and
• an envelope layer surrounding the core,
• the core includes the first fiber composite material,
• the first fiber composite material includes glass fibers,
• the envelope layer includes a second fiber composite material, wherein the second fiber composite material includes aramid fibers being enveloped by a plastic matrix material, and
• the weakened sites are generated by at least one of:
• buckling loads, bending loads or breaking loads.
