Importing Devices for Clinical Investigations

When a medical device becomes the subject of a clinical investigation, its regulatory identity changes: it is no longer a product to be placed on the market but an instrument to produce evidence. The investigational device therefore passes through a separate permit chain: the ethics committee evaluation and the competent authority process establish the legal basis for the device's use within the investigation, and the import rests on that basis. The chain resembles medicinal product trials but has its own distinctions: on the device side, the investigation version, hardware-software integrity, maintenance and calibration responsibility, and the device's fate after the trial are the decisive issues. A device without a CE mark can enter the country only with investigation status and under defined conditions; if the status is not documented, the product is treated as a commercial import at inspection. This article explains the permit basis of investigational device import, the status and labelling rules, the customs practice and the obligations continuing through the investigation.

Who is this for?

This guide is for every role on the supply side of device clinical investigations. Sponsors and their local representatives run the trial file and the supply plan together. CRO teams synchronise the shipment calendar with site activation. Investigators and site coordinators own the device's acceptance, use, maintenance and records. The importer and customs broker carry the set documenting the investigation status to customs. Quality units monitor the device's quality state during the investigation and manage corrective actions. Biomedical and technical teams plan installation, calibration and service needs. Regulatory units keep the ethics and authority correspondence in a single file. At audit the question is twofold: under which permit did this device enter, and who did what with it during the investigation. The pieces of the answer can sit in different hands; the file must be one.

Which products does it cover?

The scope is every device and related material defined by intended use in the investigation protocol. The device in its investigation version, the hardware-software whole produced with the function or configuration for which evidence is collected; a device used for a different purpose in the trial's investigation arms even though CE-marked; standard-care products procured for comparison; IVD devices and kits brought for performance evaluation; and investigation-specific accessories, consumables and connection components. Auxiliary equipment outside the definition, for instance general-purpose office or measuring devices, carries no investigational device status; but if defined in the protocol it enters the record scope. The boundary is this: the protocol and intended use decide whether the device is an investigation device; the status can differ even when the physical product is the same. GTİP classification runs independently of status and comes from the device tariff; the status is shown at customs with the document set.

When does it apply?

The investigational device regime applies whenever a device clinical investigation is run; the moments that weigh it down are known. Where a device without CE or used outside CE scope is to be brought, the permit file must be strengthened with the device's risk analysis and the investigation rationale. When the investigation version's hardware-software version changes, the change assessment runs on both the authority and the ethics side. In multi-centre trials, each centre's own infrastructure and acceptance records are built. The device's maintenance and calibration during the investigation are carried out by the manufacturer or authorised service and recorded. Device failure and corrective action tie into the safety reporting chain. At the trial's end the device's fate is planned: return, destruction, transfer to another investigation, or use under defined conditions; each option demands its own documents. In early termination the device fate is a mandatory row of the closure file. At every new shipment, compliance with the permit frame is re-verified.

Legal framework and authority

The frame comes from the clinical investigation provisions of the medical device legislation and the ethics assessment arrangements. In Türkiye, which applies the European device regulation nationally, the planning, evaluation and monitoring of device clinical investigations are defined in that frame; the investigation use of devices outside CE is one of the exception routes the regulation allows and is bound to its conditions. Ethics committees assess independently for participant safety and ethical suitability. The competent authority is TİTCK: it evaluates device clinical investigation applications, issues permits, monitors safety reporting and inspects. On the customs side the transaction runs through Ministry of Trade administrations; the investigation status is shown with the document set and the status distinction is made for product safety inspection purposes. The difference from medicinal trials is that the device's physical presence remains in the field through the investigation and the maintenance-calibration responsibility continues. Current regulations and guides must be tracked on the authority's official pages; application contents are updated over time.

Step-by-step process

1. Define device use in the protocol: investigation device or comparator; which version and configuration.
2. Run the device's status analysis: CE status, intended use within the investigation and the permit type required.
3. Prepare the ethics and authority file: protocol, investigator information, device technical documentation, risk analysis and label mock-ups.
4. Track the assessment; answer additional requests in a versioned and consistent way.
5. Tie the permit output to the supply chain: let the importer, customs document set and depot plan reference the permit.
6. Approve the investigation-specific label: with the statement that it is solely for clinical investigation and the mandatory information.
7. Plan the shipment: tie the installation, calibration and site training calendar to the first enrolment date.
8. Set up acceptance and records: device identity, version, acceptance minute and the maintenance-calibration ledger.
9. Monitor through the investigation: safety reporting, corrective action and accountability records.
10. Apply the end-of-trial fate plan and bind it to the closure file.

Document checklist

• Device section of the protocol, current version and amendments.
• Device technical documentation and the investigation version definition.
• CE status and conformity assessment information; if without CE, the rationale.
• Risk analysis and participant safety assessment.
• Ethics committee approval and competent authority permit, complete and dated.
• Investigation-specific label mock-up and approval.
• Import document set: permit reference, declaration, customs records.
• Installation, calibration and maintenance records.
• Use and accountability ledgers, site by site.
• Safety report and corrective action records.
• End-of-trial fate minute: return, destruction or defined use.

Parties and responsibilities

The matrix's critical point is continuity: the investigational device's responsibility does not end with the shipment but runs to the investigation's end. Without maintenance and calibration records, data reliability cannot be shown; without accountability, device safety cannot be shown.

Exceptions and edge cases

The edge of investigational device practice is full of real operational questions. The off-label investigation use of a CE-marked device requires investigation status; the mark alone grants no freedom. Is a standard-care device used in the comparison arm recorded like an investigational device; the rule is the definition in the protocol. If the device's software update changes the investigation version, the change assessment runs and the site is informed. If a backup device must engage on failure, the backup must also sit within the permit frame; a backup brought instantly stays undocumented. For rented or borrowed devices, responsibility is clarified by contract; the record obligation arises with use, not with the party. IVD products under performance evaluation are subject to the investigation provisions of their own regulation. At the trial's end, transferring the device to another investigation is possible with the transfer of the permit frame and the records. In every edge case the answer rests on the same principle: intended use and permit frame must overlap in writing.

Common mistakes

The most common mistake is dispatching the device before the permit arrives; the product cannot document its status at customs. The second is producing the investigation-specific label without approval; the device stays in quarantine at the depot. The third is leaving a CE-marked device undocumented in off-protocol investigation use; the mark exists but the use is out of scope. The fourth is not keeping calibration and maintenance records; data reliability is questioned. The fifth is not carrying device version changes into change assessment; the permit file goes stale. The sixth is planning backup device arrivals ad hoc; the backup stays undocumented. The seventh is thinking about the end-of-trial fate at closure; the return and destruction plan must be built from the start. The eighth is leaving use ledgers to site memory; undocumented use cannot be explained at audit.
