Wireless Medical Devices

The term “wireless” in Industry 4.0 is not limited to only wireless communication; it is backed up by modern technologies such as the Internet of Things (IoT) and Cloud Computing for effective and robust system functionality. In the health and medical domain, medical devices are labeled as wireless medical devices when the device itself, or a part of the device, fulfills a health service using wireless communication protocols. Indeed, since patient care and safety are the highest priorities, these devices should follow FDA safety guidelines before they are released in the market.

There are myriad wireless communication protocols that can be integrated with medical devices. Some of them include Wi-Fi, Radio Frequency Identification (RFID), Zigbee, Bluetooth, Near Field Communication (NFC), or a simple cellular network. Irrespective of the protocol selection, the major functionalities of wireless medical devices include either communicating or sending data between systems, continuous remote monitoring of patients, and controlling system components. For example, physicians can remotely access and monitor patient data without knowing the actual patient location. Also, using IoT/Cloud, remote data access, and modern analytical tools, remote intelligent systems can be deployed to deliver precise drug levels based on the results provided by analytics. An example of such a system is Wi-fi or a Cloud-based intelligent insulin delivery device. Also, patient records can be maintained using RFIDs as the access points. In such cases, doctors can access the entire patient’s medical history by scanning the uniquely associated RFID.1

As stated formerly, these wireless medical devices hold patient data while executing functionalities such as data transfer and patient monitoring. This data drives future system decisions and therefore the accuracy of this data is extremely vital. If manufacturers are revamping their traditional systems with novel data communication protocols, they should validate all functionality at every stage to identify any risks associated with the system. The other major aspect of safety is security. Being a data network protocol, manufacturers should utilize the latest network security frameworks to avoid any unauthorized access or malicious attacks. Additionally, they should consider using security protocols which are also recognized by the FDA which ensures the system is truly secure against a potential cyberattack. If the FDA finds that the wireless medical device follows their essential safety guidelines and reaches the required levels of safety and efficacy, the FDA grants market clearance or approval.2

To sum up, wireless medical devices are enhancing healthcare services by providing sophisticated features such as continuous patient data monitoring and remote patient system control or data access. Surely, manufacturers should take care that their medical device with wireless protocol is well tested, documented, and most significantly, it is safe and secured enough to be utilized in the market.

FDA Adverse Event Reporting 

FDA Adverse Event Reporting 

When reporting an Adverse Event to the Food and Drug Administration (FDA) the best method is to utilize the FDA Adverse Event Reporting System (FAERS). FAERS is a database that contains adverse event reports, product quality complaints that led to an adverse event, and medication error reports1. All FAERS reports are easily accessible to the public. 
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.
