Comparing HP 8753 and NanoVNA For Medical Device Design

Comparing HP 8753 and NanoVNAThis blog compares a traditional Vector Network Analyzer (VNA), the HP 8753, with a NanoVNA for use by the budget constrained engineer developing a medical device.
A Vector Network Analyzer or VNA injects a known signal into a circuit, and determines what changed about the signal after it leaves the circuit. VNAs are used during the development process of a device, to characterise and verify the performance of circuits such as amplifiers, filters, antennae, cables, etc. This is very common, especially if a given device operates at higher frequencies, where nonidealities can play a bigger role and are harder to predict.

How to Improve Emotional Interaction With a Medical Device

Emotional Interaction Medical DevicesVisual rhetoric and emotional interaction in Medical Devices
Frequently in the medical device industry, the tangible importance of the aesthetic design of an object can be downplayed. It can be considered dressing or fluff and not important in the development of the device. However, aesthetic personality, visual rhetoric or emotional interaction with a medical device influence the experience that an operator and a patient have with the device.

Variations Between FDA and EU MDR Requirements for Clinical Investigations

Clinical Investigations EU MDR FDA
Clinical investigations are defined within both FDA and EU MDR as the systematic investigation involving one or more human subjects, undertaken to collect data and assess the safety or performance of a device. Using the clinical data to demonstrate that the device meets the safety and effectiveness considerations is an important step in the device lifecycle.
Here, we will look at some of the differences between FDA and EU MDR process and requirements for clinical investigations.

Optimizing QA/RA Value in Medical Device Development

QA/RA Value Medical Device DevelopmentWhen thinking about the roles of Quality Assurance (QA) and Regulatory Affairs (RA), I like to use the metaphor of the trail blazer and the guide, RA is there to blaze the trail and find the path, QA is there to keep the team on that path and away from pitfalls and hazards.
RA does this by monitoring and reviewing the regulatory landscape, understanding the applicable laws and regulations, but also knowing about recent decisions by regulatory bodies and how interpretations of these directives and guidances can vary. QA keeps projects on track by being fully engaged in the Quality Management System (QMS) and knowing what needs to be done to ensure that the project is successful as well as compliant.
