Key takeaway: The ability to reuse product data can dramatically reduce the time taken to design, gain regulatory approvals, and ultimately bring new medical devices to market. Time equates to money in any business, and in the world of medical device design and manufacturing, that can mean BIG numbers! Depending on the route taken, following FDA regulations, the average cost to bring a medical device to market through the Premarket Approval pathway is $94 million. The less intensive 510(k) process averages out at $31 million.

Using unstructured tools such as Word and Excel when doing risk management for medical devices could result in harm to a patient. Why? Because many medical devices are complex, with hundreds to thousands of inter-related design inputs/outputs, testing, and risk management data. Managing that amount of data manually is nearly impossible when using tools like Word and Excel...

Systems engineering should be used more often in medical device product development. This may be a strong statement, but it can be transformative for device development through decreased development costs, streamlining of interactions with the FDA, and reduced time-to-market. We would like to address this through a series of articles on systems engineering role in Medical Device Product Development of which this is the first.

Often in medical device product development, functions exist in silos. Risk, requirements, and test management functions often exist separately, on their own - different systems, different teams, different objectives. Yet, the data related to these functions are both continuously changing and highly dependent on one another. Some type of process is needed to (1) manage the effect of changes across all three systems and (2) provide evidence of a process for notified bodies if and when needed.

SEPARATE RISK MANAGEMENT AND FMEA FOR BETTER MEDICAL DEVICE DEVELOPMENT. The below is an excerpt of the article originally published on MDDI. FMEA (Failure Mode and Effects Analysis) is utilized to identify potential failure modes in the design or manufacturing of a product. But risks associated with medical devices are not created by failures alone. A product may never fail, but there are still potentially many other risks.

Commonly issued after an FDA inspection, a Form 483 informs a company of observations requiring corrective actions. The Form 483 is often referred to as “Inspectional Observations” as it is a list of conditions or practices that indicate a potential violation of FDA requirements. The form is compiled in order of importance and is considered a snapshot of potential issues; it should not be considered all-encompassing.
