EMDN P04: Respiratory Prostheses

Complete hierarchy for EMDN group P04 in category P (Implantable Prosthetic and Osteosynthesis Devices): 3 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.

    • P0401Tracheobronchial ProsthesesMDR 100.0% Class IIb · n=693MDD 100.0% Class IIb · n=116terminal

      Registered in EUDAMED under MDR with this code: 693 of 693 devices carry Class IIb on their registration (as of 8 Sep 2026).

      • 693 Class IIb (100.0%)

      Registered in EUDAMED under MDD with this code: 116 of 116 devices carry Class IIb on their registration (as of 8 Sep 2026).

      • 116 Class IIb (100.0%)

      Counted once per primary UDI-DI, using the class on the registration. The class of a device comes from the MDR and IVDR classification rules for its intended purpose, so a code is evidence of how others registered, not a determination. MDD and IVDD classes are the directive classification and can differ under MDR or IVDR.

      Registered in EUDAMED under MDR with this code: 24 of 24 devices carry Class I on their registration (as of 8 Sep 2026).

      • 24 Class I (100.0%)

      Counted once per primary UDI-DI, using the class on the registration. The class of a device comes from the MDR and IVDR classification rules for its intended purpose, so a code is evidence of how others registered, not a determination.

How P04 is structured

3
terminal codes, selectable in a device record
0

67%
fallback entries: Other and Accessories

The Respiratory Prostheses branch runs 1 level deep. Every code below is terminal.

1 terminal code is an “- Other” entry and 1 is an “- Accessories” entry, 67% 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.

Frequently asked questions

Which P04 codes can be used in a EUDAMED device record?
All 3 codes listed under P04 (Respiratory Prostheses) are terminal, so any of them can be selected in a device record.
How deep is the P04 hierarchy?
The P04 branch runs 1 level below the group code.
How many P04 codes are catch-all entries?
1 terminal code under P04 is an "- Other" entry and 1 is an "- Accessories" entry, 67% of the branch. The remaining 1 name a specific device type.
