摘要：An assembly for positioning an embolization coil (4) in the vascular system. Theassembly includes a guidewire having a relatively flexible distal section (6), which has acentral core (7) and a threading coil (10) , the distal turns (11) of which are arranged withsuch mutual spacing (12) that the embolization coil can be threaded in and out of thethreading coil. The distal end section of the guidewire is manufactured with an elongated,rotationally symmetrical member, such as cylindrical member (13), and the peripheralsurface of the member is provided with a bonding layer (25). Then the distal turns of thethreading coil are positioned in the desired helical shape on the external side of themember, and the bonding layer is activated so that the distal turns are fixed to themember in this shape. The cylindrical member (13) has an outer diameter which is afraction smaller than the inner diameter of the embolization coil (4) and has a lengthwhich is longer than the extent in the axial direction of the guidewire of at least three ofthe distal turns (11) of the threading coil. The distal turns of the threading coil are fixedto the external side of the member, so that the thread provided is geometrically stableand smooth-running.
