How to externalize software development for a medical device?

Case example

You are a medical device company and you want to replace your old products by “smart” ones. Your competitors are doing it and you customers want them. “Smart” means something like an tiny computer (its amazing how small they are), with an operating system and big software. For electronic stuff, you have your own engineers or you have your subcontractors, which you have been working for 20 years with. They knew how to design embedded software on microchips. But they don’t know how to design software of higher level, with intelligent behaviour and complex algorithms.

Template: Risks Analysis Report

Templates section wouldn't be a templates section without something about risk analysis. Error repaired!

Here is the Risk Analysis Report Template. It contains sections compliant with IEC 62304, IEC 62366 and ISO 14971. It is best used in conjunction with the SRS template.

Please, fell free to give me feedback on my e-mail contact@cm-dm.com

New Device Classification Guidance published by GHTF: consequences for medical imaging software

The GHTF (Global Harmonization Task Force) issued a draft of a new guidance on medical device classification They recommend to implement four classes for medical devices based on intended use: from class A (lowest risk) to class D (highest risk). And they give a set of rules on how to choose the classification of the devices.

Comparison with regulations

Wait, I've already seen this elsewhere. Classification of devices in Europe (CE mark) and in Canada have systems very similar to what GHTF recommends. This is a good thing to have an ongoing harmonization process. National regulations copy what GHTF recommends and GHTF copies what national regulations require. This is a virtuous circle. Maybe one day the FDA will implement this classification system.

Certification of software medical devices in Canada

In How to classify and CE mark software, I tried to make a thorough explanation about how to obtain CE mark for software medical devices. Here is a short explanation about Canadian rules.

Software Medical Devices. How to obtain market homologation?

The homologation of a medical device is a complex task and can become a nightmare with devices with a high level of risk. It involves many standards and regulations, different from one country to another: FDA in the USA, CE Mark in Europe, CMDCAS in Canada, KFDA in South Korea, and so on …

Fortunately, most of these regulations have common requirements and rely on ISO standards, the most important standards being ISO 13485 and ISO 14971. If you meet the requirements of these standards, you increase your chances of passing the homologations for the devices with low risk. For devices with high risk, these standards are (almost) mandatory.

iPhone and Android applications are mobile medical devices

The boom of mobile apps on smart phones clearly impacts the medical devices industry. Doctors are eager to have the last software gadget (the app) on their hardware gadget (the smartphone, the tablet). As a result, many apps on Apple Store and Android Store fall into the scope of medical devices: terminal to remotely display medical images, apps to compute doses of medicines, an so on ... The list is long.

And gess what? These apps shall be certified before being put in the Apple-Android stores. The FDA is clear about these "mobile medical apps" in a draft guidance published in july 2011: "For the subset of mobile medical apps that are subject to regulatory oversight, manufacturers must meet the requirements associated with the applicable device classification." see the Draft Guidance. For the CE mark, the rule is the same, mobile medical apps fall into the category of active medical devices.

The big family of medical devices is getting more and more children. Welcome to the baby smartphone apps!

Template: Project Management Plan

Here is the Project Management Plan Template.

This template doesn't contain anything technical. Has it something to do with software development? Yes, it has. It contains all the answers to questions like: Who, What, Where, When, How, Why and How much? You can do all the technical stuff you want, but without a minimum of organisation, your software will never be certified. This template deals with sections of IEC 62304 about project organisation. Use it to answer to those requirements of the standard.

Template: Design consolidation document

This template is useful for people addicted to extreme programming: Design consolidation document.

Reviewers are not confortable with iterative processes. When you look at recognized standards for soft development, like IEC 62304, you can see that they are stuck to the waterfall process. Extreme programming isn't their cup of tea!

How to classify and CE mark software

Medical devices shall have CE mark before being sold in the EU. The process to have CE mark can be summarized this way:

  1. Determining the class of the device,
  2. Choosing the CE procedure to apply,
  3. Declaring CE conformity of the device.

Software follows exactly the same process as other devices. Here are the steps to follow to CE mark software.

5 recommendations to engineers developing medical device software

A lot of standards and regulations exist about medical devices: how to design, to produce, to sell, to monitor their use … Everything about each step in the life of devices, from the initial idea 10 years before selling anything, to the archiving of records 10 years after the last item has been sold. A lot of specific standards or guidances on how applying medical devices standards exist about software. That’s the consequence of software being very specific (I should say peculiar), compared to other components in medical devices. Conception is the most critical part in the lifecycle of software. Software is never 100% finished, user always want enhancements and modifications.

From my own experience in the field, I gathered 5 basic recommendations you should follow.

ISO and IEC standards for software in medical devices in a nutshell

Here is a short description of ISO and IEC standards related to software and medical devices.

The starting point is legal. Government agencies give the authorizations to manufacturers to sell their devices. These agencies rely on standards to ensure that the device was designed and manufactured in a good and safe way. Given these regulations, medical device manufacturers have to adhere to these standards. Full stop.

Let's see what these standards are.
