J-tip protective cap

A J-tip protective cap configured for protecting a J-tip of a medical guide wire, comprising:

• a proximal sleeve section;
• a distal hollow disk-shaped J-tip receiving section, which extends distally and laterally on one side in a distal end region of the sleeve section with a disk longitudinal axis perpendicular to a longitudinal axis of the sleeve section, wherein an interior of the J-tip receiving section forms a J-tip receiving space;
• and
• a J-tip passage slot which leads into the J-tip receiving space at a proximal side of the J-tip receiving space and which is composed of an axial slot section in the sleeve section and a circumferential slot section in the J-tip receiving section,
• wherein
• the J-tip receiving space comprises a tapered region, in which the J-tip receiving space tapers in a radially outward direction in its lateral width, and opposite inner sides of the J-tip receiving section form, in cross section, two opposing J-tip point contact surfaces with the guide wire in the tapered region of the J-tip receiving space.
