4. Pre-Clinical Testing

Bench Testing:

• Conduct mechanical, electrical, and software testing to verify device performance and safety.
• Develop test protocols and acceptance criteria based on design inputs.
• Document all testing activities and results in the test report.

Biocompatibility Testing:

• For devices in contact with the body, conduct biocompatibility tests as per ISO 10993 standards.
• Identify the specific tests required based on the device’s materials and intended use.
• Compile biocompatibility test reports and ensure they meet regulatory requirements.

Animal Studies:

• If necessary, conduct pre-clinical studies on animals to evaluate safety and efficacy before human trials.
• Obtain ethical approval for animal studies and follow relevant guidelines.
• Analyse and document the results of animal studies to support regulatory submissions.

5. Clinical Evaluation

Clinical Investigation Plan:

• Develop a comprehensive plan outlining study objectives, methodology, and endpoints.
• Define inclusion and exclusion criteria, sample size, and statistical methods.
• Ensure the clinical investigation plan complies with regulatory requirements and ethical standards.

Ethics Approval:

• Obtain approval from an Institutional Review Board (IRB) or ethics committee for clinical trials.
• Prepare and submit all necessary documentation, including the clinical investigation plan, informed consent forms, and investigator brochures.

Clinical Trials:

• Conduct trials to gather clinical data on safety and performance.
• Recruit and train investigators, monitor study sites, and ensure compliance with the clinical investigation plan.
• Collect and analyse clinical data, addressing any adverse events or deviations from the study protocol.

Clinical Evaluation Report (CER):

• Compile and analyse clinical data to demonstrate compliance with essential regulatory requirements.
• Summarise clinical findings, including safety and performance outcomes.
• Ensure the CER is comprehensive and addresses all relevant regulatory criteria.

6. Conformity Assessment and Submission

Technical Documentation:

• Prepare detailed documentation, including:
  • Design dossier
  • Risk management file
  • Verification and validation reports
  • Clinical evaluation report
  • Labelling and Instructions for Use (IFU)

Estonian Health Board Submission:

• Submit the appropriate documentation to the Estonian Health Board based on the device classification:
  • Class I: General controls, often exempt from detailed premarket submission.
  • Class IIa, IIb, and III: Submit a more detailed Medical Device License application including clinical data and safety information.

7. Estonian Health Board Review and Approval

Review Process:

• The Estonian Health Board reviews the submission for completeness, scientific validity, and compliance with regulatory requirements.
• Prepare to respond to queries and provide additional information during the review process.

Interactive Review:

• Engage with the Estonian Health Board during the review process to address questions and provide additional information.
• Maintain open communication with the regulatory authority to facilitate a smooth review process.

Approval/Authorisation:

• Upon successful review, the Estonian Health Board grants market authorisation.
• Receive the official documentation confirming the device’s approval for market entry.

8. Manufacturing
