Design Process

• Develop Initial Designs: Use CAD software to create initial designs and prototypes, followed by iterative improvements. Utilise simulation tools and modelling to test design concepts.
• Prepare Documentation: Prepare detailed design documentation, including drawings, specifications, and material lists.

Verification and Validation (V&V)

• Verification: Ensure that design outputs meet specified design inputs through rigorous testing and inspection. Conduct bench tests, usability assessments, and software validation as applicable.
• Validation: Confirm that the final product meets user needs and intended use through clinical evaluations or user trials. Compile validation results to demonstrate that the device meets its intended purpose.

Design Review

• Conduct Reviews: Conduct regular design reviews with cross-functional teams to ensure design compliance and address any issues. Document outcomes and track action items.

3. Regulatory Strategy

Classification

• Determine Classification: Determine the appropriate classification of the device based on its intended use and risk level (e.g., Class I, II, or III) according to Thai FDA’s classification rules.

Regulatory Pathway

• Define Pathway: Develop a regulatory submission plan detailing the necessary documentation and timelines. Stay updated on regulatory changes and guidelines issued by the Thai FDA.

Quality Management System (QMS)

• Implement QMS: Implement a QMS compliant with ISO 13485 to manage quality throughout the product lifecycle. Develop procedures for design control, risk management, supplier management, and post-market surveillance.

4. Pre-Clinical Testing

Bench Testing

• Perform Testing: Conduct mechanical, electrical, and software testing to verify device performance and safety. Develop test protocols and acceptance criteria based on design inputs.

Biocompatibility Testing

• Conduct Tests: For devices in contact with the body, conduct biocompatibility tests in accordance with ISO 10993 standards. Compile test reports to demonstrate regulatory compliance.

Animal Studies

• Conduct Studies: If necessary, conduct pre-clinical studies on animals to assess safety and efficacy before human trials. Obtain ethical approval and document results.

5. Clinical Evaluation

Clinical Investigation Plan

• Develop Plan: Create a detailed plan outlining study objectives, methodology, and endpoints. Define inclusion and exclusion criteria, sample size, and statistical methods.

Ethics Approval

• Obtain Approval: Obtain approval from an Ethics Committee or Institutional Review Board (IRB) for clinical trials. Prepare and submit necessary documentation.

Clinical Trials

• Conduct Trials: Conduct trials to gather clinical data on safety and performance. Monitor study sites and ensure adherence to the clinical investigation plan.

Clinical Evaluation Report (CER)

• Compile Report: Analyse clinical data to demonstrate compliance with regulatory requirements. Summarise findings related to safety and performance.

6. Conformity Assessment and Submission

Technical Documentation

• Prepare Documentation: Compile detailed documentation, including the design dossier, risk management file, verification and validation reports, clinical evaluation report, and labelling and instructions for use (IFU).

Regulatory Submission

• Submit to Thai FDA: Submit the necessary documentation to the Thai FDA based on the device classification:
  • Class I: Generally requires a simpler notification or registration process.
  • Class II and III: Requires a more comprehensive application, including clinical data and safety information.

7. Thai FDA Review and Approval

Review Process

• Thai FDA Review: The authority reviews the submission for completeness, scientific validity, and regulatory compliance. Prepare to respond to queries and provide additional information.

Interactive Review

• Engage with Thai FDA: Maintain open communication with the Thai FDA throughout the review process to address questions and facilitate a smooth review.

Approval/Authorisation

• Obtain Authorisation: Upon successful review, receive market authorisation. Obtain official documentation confirming the device’s approval for market entry in Thailand.

8. Manufacturing

Production Planning

• Develop Plan: Create a comprehensive manufacturing plan, including material procurement, production schedules, and resource allocation. Qualify suppliers to meet quality and regulatory standards.

Process Validation

• Validate Processes: Ensure consistent product quality through process qualification and validation studies. Document results in a process validation report.

Quality Control

• Implement Measures: Establish quality control procedures and conduct regular inspections and tests to monitor and maintain product quality.

Packaging and Labelling

• Ensure Compliance: Design packaging to protect the device during transport and storage. Develop labelling that includes instructions for use, warnings, and other necessary information.

9. Post-Market Surveillance

Post-Market Surveillance Plan

• Develop Plan: Define procedures for collecting and analysing post-market data, including user feedback and adverse event reports.

Vigilance Reporting

• Report Incidents: Implement a system for tracking and managing vigilance reports. Report adverse incidents and safety concerns to the Thai FDA as required.

Periodic Safety Update Reports (PSURs)

• Submit Updates: For higher-risk devices, submit regular safety updates to the Thai FDA. Include data on device performance, adverse events, and corrective actions taken.

Customer Feedback

• Collect Feedback: Implement a system for managing customer complaints and addressing product issues.

10. Continuous Improvement

CAPA System

• Implement CAPA: Address quality issues and prevent recurrence by investigating root causes and developing corrective actions.

Internal Audits

• Conduct Audits: Ensure ongoing compliance with regulatory requirements and QMS through regular internal audits. Document findings and track corrective actions.

Training and Development

• Provide Training: Keep employees updated on regulatory changes and industry best practices through continuous training programmes.

R&D and Innovation

• Invest in Innovation: Drive innovation and improve existing products by investing in research and development. Foster a culture of continuous improvement within the organisation.
