Verification & Validation of Medical Devices

Validation and verification are critical components of the quality management system (QMS) that ensure the effectiveness and reliability of all elements involved in the development, distribution and use of medical products.

Verification: Making sure you built the product right. It’s like checking off items on a list to make sure you’ve done everything as planned.

Validation: Making sure you built the right product. It’s like asking, “Does this really solve the problem or meet the user’s needs?”

 

Verification

Verification is the process of evaluating whether specified requirements have been met. It typically involves checking and confirming that a product, process, or service meets predetermined specifications, standards, or regulations. In the context of ISO 13485, verification activities may include:

• Reviewing design specifications to ensure they meet regulatory and customer requirements.
• Conducting inspections, tests, or analyses to verify that products or processes meet established criteria.
• Performing audits or reviews to confirm compliance with documented procedures and standards.
• Verifying the competency and qualifications of personnel involved in the production or servicing of medical devices.

Verification activities help ensure that products or processes are developed or implemented correctly according to predefined criteria, thereby reducing the likelihood of defects, errors, or non-conformities.

 

Validation

Validation is the process of confirming that a product, process, or system meets the intended requirements and is suitable for its intended use. It involves demonstrating that the output of a particular process meets the needs and expectations of stakeholders. In the context of ISO 13485, validation activities may include:

• Conducting performance testing or clinical trials to demonstrate that a medical device meets specified performance and safety requirements.
• Evaluating the effectiveness of manufacturing processes to ensure consistent production of conforming products.
• Assessing software systems to verify their functionality, reliability, and security in accordance with regulatory requirements.
• Validating sterilisation processes to ensure the effectiveness of microbial reduction or elimination.

Validation activities provide assurance that products or processes are fit for their intended purpose and capable of meeting customer needs and regulatory requirements. It helps mitigate risks associated with product failures, patient safety issues, and regulatory non-compliance.

 

Launching Your Medical Product

Prior to launching your medical product there are several factors that need to be assessed.

• Ensure technical documentation is complete and up-to-date
• Evaluate the need for re-testing based on any final changes or updates
• Establish post-market plans, including monitoring, reporting, and addressing issues
• Implement a system to capture complaints and feedback from users
• Finalise packaging and labelling, ensuring compliance with regulatory requirements
• If launching in Europe, assess whether any significant changes require reporting to the competent authorities, such as notifying Notified Bodies or Competent Authorities about changes to the product or its intended use.
