The review process conducted by China's NMPA (National Medical Products Administration) for medical devices is thorough and involves several key steps to ensure compliance with regulatory standards and safety requirements. Here's an overview of the typical review content for NMPA certification of medical devices:

1. Document Review:

   • Technical Documentation: NMPA conducts a detailed review of the technical file or dossier submitted by the manufacturer. This includes verifying the completeness and accuracy of information related to device design, manufacturing processes, quality management system (QMS), risk management, labeling, and clinical data (if applicable).
   • Quality Management System (QMS): Assessment of the manufacturer's QMS documentation to ensure compliance with ISO 13485 standards and regulatory requirements.

2. Technical Review:

   • Device Performance: Evaluation of the device's performance characteristics, including testing results, to ensure they meet specified standards and performance criteria.
   • Safety and Efficacy: Assessment of clinical data (if provided) to evaluate the device's safety and efficacy in accordance with NMPA guidelines and requirements.

3. Site Inspection (Audit):

   • On-Site Inspection: For certain classes of medical devices or based on risk assessment, NMPA may conduct on-site inspections at the manufacturer's facilities. This inspection verifies the implementation of QMS, adherence to manufacturing practices, and compliance with regulatory standards.
   • Audit of Clinical Data: If clinical data is part of the submission, NMPA may also audit the clinical study sites and data to ensure validity and reliability.

4. Risk Assessment and Decision Making:

   • Risk Evaluation: NMPA assesses the risk associated with the device and evaluates the effectiveness of the manufacturer's risk management processes.
   • Decision Making: Based on the review findings, NMPA makes a decision regarding the certification or approval of the medical device. This decision considers whether the device meets safety, efficacy, and quality standards required for market approval in China.

5. Post-Market Surveillance Requirements:

   • Requirements: Manufacturers are required to establish and maintain post-market surveillance systems to monitor the performance of their devices after they enter the market. NMPA reviews these systems to ensure ongoing compliance and safety.

Overall, the review content conducted by NMPA aims to thoroughly evaluate each aspect of the medical device's design, manufacturing, quality control, clinical performance, and post-market surveillance. By adhering to these rigorous review processes, NMPA ensures that only safe, effective, and high-quality medical devices are authorized for sale and distribution in China.
