EMDN C04: Cardiovascular Guidewires
Complete hierarchy for EMDN group C04 in category C (Cardiocirculatory System Devices): 26 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.
Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

How C04 is structured
The Cardiovascular Guidewires branch runs 3 levels deep. 12 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 26 codes marked terminal.
9 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 38% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.
The largest sub-branch is C0401 (Coronary Artery Guidewires), holding 6 of the 26 terminal codes.
Frequently asked questions
- Which C04 codes can be used in a EUDAMED device record?
- 26 of the 38 codes listed under C04 (Cardiovascular Guidewires) are terminal and can be selected. The other 12 are branch headings that cannot.
- How deep is the C04 hierarchy?
- The C04 branch runs 3 levels below the group code. Its largest sub-branch is C0401 (Coronary Artery Guidewires), which holds 6 of the 26 terminal codes.
- How many C04 codes are catch-all entries?
- 9 terminal codes under C04 are "- Other" entries and 1 is an "- Accessories" entry, 38% of the branch. The remaining 16 name a specific device type.
Not sure which level to stop at, or which of two plausible codes to submit? The guide to choosing an EMDN code walks the decision level by level, with a worked example and the mistakes that get a EUDAMED registration rejected.
