Design validation is establishing by objective evidence that device specifications conform with user needs and intended use s 21 cfr 820 3.
Medical device design verification.
It includes any activity that can provide proof that the legal requirements are being fulfilled.
Design control guidance for medical device.
Also to complicate matters a bit outside the medical device industry verification and validation also mean different things.
For a simple visual.
Design process and software are the most common in the medical device industry.
In qsr and iso 13485 2003 design verification confirms that the design output meets the design input requirements.
Like all such processes the success of design verification depends on the success of the upstream processes that precede it.
This is part of a series of articles covering the procedures in the book statistical procedures for the medical device industry.
Medical devices are also becoming smaller and more complex in design sometimes using advanced engineered plastics.
Given that there are 11 types of testing that you as a medical device manufacturer are advised to perform in order to assess the design quality of your medical device.
And each means something different.
Simply put verification confirms that the design output meets the design input requirements while validation ensures that user needs are met by the medical device.
Design verification 21 cfr 820 30 f design verification is confirmation by objective evidence that design output meets design input.
They make pass fail decisions as to whether the product s design outputs specifications drawings ensure each design input requirement requirements.
There are multiple types of verification and validation.
Design verification is just one element in the overall design controls process a multi step framework for ensuring that your medical device is safe and effective for the intended user.
In some cases since type i and type ii have risks alpha and beta i see companies attempting to pull in medical device risk management iso 14971 2007.
This makes the process of validation and verification v v even more important not only to comply with regulations but also design the highest quality part and production process.
When collected together in a v v report the combination of verification and validation test results along with traceability back to user needs product requirements and design specifications provides part of the evidence the fda requires when submitting a medical device for clearance.
