Medical Device Validation Rationale.

Medical Device Validation 510K and the importance of your suppliers being fully conversant and compliant with all the regulatory obligatory requirements has become a rather burdensome load for some companies and an unacceptable load for others. However: the growing expectation is that these subcontractors will; step by step,  increase their cGMP compliance level.

This continuing upsurge in subcontracter cGMP compliance must result in the industry becoming familiar with the authoring, reviewing and approval of the full suite of cGMP document.  Documents such as: IQ,- OQ, - DQ, - PQ,- VRA,- VP, - URS, were born.

Whether Just completed a supplier assessment, how important was your documentation? How important was your justification for your decision? Have you been biased in your judgement? Were your priorities right? How did you get it so wrong? These are questions that are in the minds of all persons affected by an adverse audit outcome. To make certain that you are going to be ‘squeaky clean’, every question, and every answer and observation, needs to be clearly documented. The company priorities must be understood and integrated into the weighting of the 510k Pre-Audit documents. If you are auditing on behalf of a client, they have a right to review your assessment documents, and you are required to be impartial and accurate in your findings.

Medical Device Validation by Definition.

A medical device device is:

  • An apparatus, instrument, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article.
  • Listed in the official National Formulary, or the United States Pharmacopoeia.
  • Intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals.
  • Intended to affect the structure or any function of the body of man or other animals, and which does not achieve its primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its primary intended purposes.”

Medical Devices and Other Regulated Products.

This definition provides a clear distinction between a medical device and other FDA regulated products such as drugs.

  1. If the primary intended use of the product is achieved through chemical action or by being metabolized by the body, the product is usually a drug.
  2. Human drugs are regulated by FDA’s Center for Drug Evaluation and Research (CDER).
  3. Biological products which include blood and blood products, and blood banking equipment are regulated by FDA’s Center for Biologics
  4. Evaluation and Research (CBER).FDA’s Center for Veterinary Medicine (CVM) regulates products used with animals.
  5. If your product is not a medical device but regulated by another Center in the FDA, each component of the FDA has an office to assist with questions about the products they regulate.
