Design Controls apply to the entire lifespan of a medical device, not just the initial development. For example, a Class I device can claim to promote weight loss, but it can’t claim to treat type 2 diabetes. design inputs often focus on solutions to users needs rather than documenting objective criteria for meeting user needs and regulatory requirements. Design changes. The key elements of Device Design Control involve the following elemets, which are heavily based on the above cited FDA source: 1. These include the tests and procedures that may have been developed, adapted or used to show conformance with the defined design inputs. Official word from the FDA (21 CFR 820.3) states that design validation is “establishing by objective evidence that device specifications conform with user needs and intended use (s).” Design controls are defined under FDA 21 CFR 820.30 which has a similar intent to section 7.3 Design and Development described under the guidelines for ISO 13485. This plan should reflect the specifics of how your team plans to handle each of the Design Controls in the development process. Design controls are based upon quality assurance and engineering principles. Design Outputs. A design review provides a mechanism that confirms the design is ready to move to the next stage of the process. Design Changes. Businesses are challenged by rapid changes and increasing complexity due to global markets, evolving technologies and a mobile workforce. They also pave the way to better, safer medical devices. The design input requirements shall be documented and shall be reviewed and approved by a designated individual (s). Design validation is a testing process by which you prove (“validate”) that the device you’ve built works for the end user as intended. Section 7.3.3 of ISO 13485:2016 and section 820.30 of the FDA QSR talk about design inputs. Design verification is where you test (“verify”) that your design outputs match your design inputs. FDA 21 CFR Part 820.30 design control requirements is the most important stage in the advancement of a medical device since a defective plan may prompt it being inadequate or dangerous (that is, not affirmed or cleared by the administrative organization).
