Data.gov HHS Health Technology Catalog
EUDAMED - European Database on Medical Devices
Coverage, side by side
| Data.gov HHS Health Technology Catalog | EUDAMED - European Database on Medical Devices | |
|---|---|---|
| Geographic | United States - federal agencies plus participating state, county, city, university, tribal and non-profit publishers | European Union member states, plus manufacturers worldwide registering devices for the EU market |
| Temporal | Continuously harvested index; individual records span historical archives through near-live feeds | Live registry: voluntary submissions from late 2020/2021, mandatory modules since 28 May 2026; records carry versions and update timestamps |
| Granularity | Dataset-level catalog records; underlying granularity varies by source agency | Individual device models (UDI-DI level), certificates, actors (SRN level) and vigilance/market-surveillance reports |
What each contains
They tie on 1 attribute. Pick by fit, not by loyalty.

| Best for | Discovering and sizing what US federal health-technology data exists and who holds it | Device-level regulatory intelligence on the EU market: registrations, risk classes, certificates, surveillance |
Or take both in one feed
They stack because they occupy different layers of the same ecosystem: the catalog tells you where health-technology data lives and who publishes it, EUDAMED tells you what is actually registered, certified and watched on the EU market. A defensible workflow scopes with the catalog - enumerate candidate federal datasets, rank them by demand and format fit - then grounds commercial claims in the registry, where device registrations, certificate validity and surveillance reports verify what vendors and manufacturers assert.
Align before joining. There is no native key between the two: the catalog identifies organizations by agency facet and record identifier, EUDAMED by registration numbers and UDI codes, so the bridge is entity resolution on names, subsidiaries and role types. Agree on calendar window, identity rules and geography definition first and the two views meet without friction. Datadory ships either record alone or both merged onto one delivery calendar, delivered daily, weekly, or hourly - your call. Or take both in one feed.

Fair questions
Is the Data.gov HHS Health Technology Catalog better than EUDAMED?
Better depends entirely on the question. The catalog wins whenever the question is about datasets - what health-technology data exists across US federal agencies, who publishes it, in which formats, how popular each record is. EUDAMED wins whenever the question is about devices - which models are registered for the EU market, their risk class, their manufacturer, whether their certificate still stands.
Do the two datasets overlap?
Only at the level of concepts. Both attach a named responsible party to each record, both classify records with controlled vocabularies, and both stamp records with dates. But one indexes metadata about datasets while the other registers physical products and their legal paperwork - there is no shared key between an agency catalog entry and a device UDI-DI, so the two complement rather than compete.
Which dataset covers more geography?
They cover different maps rather than more or less map. The catalog spans the United States and reaches beyond the federal level - state, county, city, university, tribal and non-profit publishers sit in the same index. EUDAMED covers the European Union member states, plus manufacturers registered anywhere in the world who sell devices into the EU market.
What can EUDAMED answer that the catalog cannot?
Device-level compliance questions. Is this specific model on the market, what risk class was it assigned, who manufactures it and under which Single Registration Number, who represents them in the EU, does their quality-management certificate expire next quarter, and what did the market-surveillance review report for Slovenia 2022-2025 find. A metadata index points at documents that might contain such facts; the registry contains the facts themselves.
Can the two be joined into one analysis?
Yes, through entity resolution rather than a direct key. The catalog names organizations - agencies and sub-agencies - while EUDAMED names manufacturers, authorised representatives, notified bodies and competent authorities with registration numbers. Where a company appears on both sides, matching names and subsidiaries builds the bridge; agree on the identity rules before joining and the two views meet cleanly.
Can Datadory deliver both datasets together?
Yes. Either record arrives alone or both arrive merged onto one delivery calendar - the discovery index beside the device registry, aligned on calendar window and entity-matching rules so the join is done before it reaches you. Delivered daily, weekly, or hourly, your call; name the agencies and modules you care about when you request the sample.
