EMDN B02: Blood Filters

Complete hierarchy for EMDN group B02 in category B (Haematology and Haemotransfusion Devices): 10 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.

          Registered in EUDAMED under MDR with this code: 23 of 23 devices carry Class IIb on their registration (as of 8 Sep 2026).

          • 23 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.

How B02 is structured

10
terminal codes, selectable in a device record
4
branch headings, not selectable
6
name a specific device type
40%
fallback entries: Other and Accessories

The Blood Filters branch runs 3 levels deep. 4 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 10 codes marked terminal.

3 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 40% 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 B0201 (Leukoreduction Filters), holding 6 of the 10 terminal codes.

Frequently asked questions

Which B02 codes can be used in a EUDAMED device record?
10 of the 14 codes listed under B02 (Blood Filters) are terminal and can be selected. The other 4 are branch headings that cannot.
How deep is the B02 hierarchy?
The B02 branch runs 3 levels below the group code. Its largest sub-branch is B0201 (Leukoreduction Filters), which holds 6 of the 10 terminal codes.
How many B02 codes are catch-all entries?
3 terminal codes under B02 are "- Other" entries and 1 is an "- Accessories" entry, 40% of the branch. The remaining 6 name a specific device type.
