Design Considerations for Interoperable Medical Devices

by | Mar 2, 2020 | Cybersecurity, FDA, Medical Devices, Ransomware

The interoperability of medical devices is an important factor to consider especially with the increase in the digital health medical devices coming into the market. Medical devices should be able to safely and effectively exchange and use information or health data to increase the efficiency of patient care.1

Interoperability will allow for data collected by one or more medical devices to be used by another product which may or may not be a medical device to facilitate health care. The products could even be from different manufacturers. FDA in its guidance document ‘Design Considerations and Premarket Submission Recommendations for Interoperable Medical Devices’ refers to interoperability as the ability of two or more products, technologies or systems to exchange information and to use the information that has been exchanged.1 Information exchange such as the UDI of the device and patient-specific data such as the ECG waveforms, can help the healthcare provider to provide improved patient care.

FDA’s guidance document focuses on the information that needs to be included in the design documents of such devices and to conduct appropriate verification, validation, and risk management activities.

FDA recommends considering the following elements for the selected interface technology:1

  1. Purpose of the Electronic Interface: Device manufacturers should consider the purpose of each of the electronic interfaces. This should include the types of data exchanges taking place (e.g., sending, receiving, issue command and control), the types of devices that it is meant to connect to, method of data transmission, the functional and performance requirements of the device as a result of the exchanged information, etc.
  2. The Anticipated Users: Manufacturers should determine the anticipated user(s) for each of the electronic interfaces. Examples of users include clinical users, biomedical engineers, home healthcare users, IT (information technology) professionals, system integrators, system designers, patients, researchers, and medical device designers. The risk management file of the product should consider the human factors study-related findings for the users of the device.
  3. Risk Management: Manufacturers should consider ways to mitigate the risks identified in the risk analysis. This includes risks that arise from others connecting to the electronic interface for which appropriate security features must be included in the design. Risk Management should also consider the usability of the device as mentioned above.
  4. Verification and Validation: Manufacturers should establish, maintain, and implement appropriate verification and validation to ensure that their devices with electronic interfaces work correctly prior to delivery, during the integration process, continue to work while in use, and through maintenance and release of software updates. Verification and Validation activities must also detect when the data is corrupted and how it can be managed.
  5. Labeling Considerations: Manufacturers should include information that users may need to connect predictably and safely to the interface for its intended purpose. This may include materials such as the device packaging, instructions for use, etc.
  6. Use of Consensus Standards: Manufacturers should consider the use of consensus standards related to medical device interoperability. FDA has recognized standards that support interoperability and encourages its use to design your product.

De Novo Classification

De Novo Classification

A device can be registered for the De Novo pathway if there is evidence of the safety and effectiveness of the device and there is not a previously legally marketed predicate device1. When determining if your device can go through the De Novo process there are two pathways available to determine the device classification.
Abbreviated 510k submission

Abbreviated 510k submission

There are three types of 510K, Premarket Notifications, which can be submitted to the Food and Drug Administration (FDA) traditional, abbreviated, and special. Abbreviated and Special 510K submissions can be utilized when the submissions meet the certain factors presented by the FDA. When submitting an abbreviated 510K the submission must include the elements that are identified in 21CFR 807.87 for the information required in a premarket notification submission.
Is your product a medical device?

Is your product a medical device?

Many marketed products are classified as medical devices and you would not even know it. Medical devices range from latex gloves and tongue depressors to respirators and heart valves. To determine if the product is considered a medical device by the Food and Drug Administration (FDA) you will need to analyze if your product meets the definition of a medical device per the Food, Drug, and Cosmetic Act1.
