A guide wire (100) for a catheter, is what for introducing and / or withdrawing fluids into the human and / or animal hollow organs, in particular in blood vessels, designed comprising an elongate hollow shaft (110) having a lumen (120) for supplying and / or discharging the fluid, as well as a coaxially at a distal end (117) of the hollow shaft (110) subsequent insertion aid in the form of a flexible wire coil (150) with a at a distal end (153) of the wire coil disposed guide wire tip (170), wherein for controlling a flexibility of the guide wire (100) in the lumen (120) of the hollow shaft (110), a core wire (130) is arranged which extends out of the lumen (120) into a longitudinal direction by the wire coil (150) up to the guide wire tip ( 170 extends out), distinguished by the fact that in a proximal direction to the guidewire tip (170) adjacent the distal inner portion (151) of the wire coil (150) via an addition to the core wire (150) formed fluid channel (151, 161, 155) with the lumen (120) of the hollow shaft (110) and communicates via an outwardly open passage opening (154) for the at least one and / or fluid has auszubringende. In a region of a proximal end (152) of the wire coil (150) is located in front of a fluid permeable connection (160) between the wire coil (150) and core wire (130), so that the wire coil (150) relative to the core wire (130) is mechanically fixed and the distal interior region (151) of the wire coil (150) having an proximal to the fluid permeable connection (160) present inner proximal portion (156) of the wire coil (150) communicates. The fluid pervious compound (260) is provided as material connection, especially as a solder joint is formed, wherein a parallel to the core wire (230) extending and in the cohesive connection (260) embedded tube (261) as channel-like passage for the supply and / or to be dissipated fluid is present.
