PROBLEM TO BE SOLVED: To provide a guide wire which can deliver and/or remove fluid in hollow organs more accurately and can be easily inserted.SOLUTION: A guide wire 100 comprises: a hollow shaft 110 having a lumen 120 for delivering and/or removing the fluid; and an insertion aid in the form of a flexible wire coil 150 connected coaxially to a distal end 117 of the hollow shaft. The wire coil has a guide wire tip 170 arranged at a distal end 153 of the wire coil and a core wire 130 is arranged in the lumen of the hollow shaft, the core wire extending out of the lumen in a longitudinal direction and through the wire coil to the guide wire tip. The guide wire is characterized in that a distal inner area 151 of the wire coil adjacent to the guide wire tip in a proximal direction communicates with the lumen of the hollow shaft by means of a fluid channel 151, 161, or 155 formed adjacent to the core wire and has at least one outwardly open passage opening 154 for the fluid to be introduced and/or removed.SELECTED DRAWING: Figure 1 |
