Three Physical Connection Methods in Medical Device Test Fixtures

Physical testing is an essential tool for product development, particularly when developing a novel medical device. When well designed, a physical test can accurately represent phenomena that are difficult to model, and physical tests can often be constructed quickly with a minimum of custom components. Here are three connection methods that I have found useful […]

Five Critical Considerations in Designing Microfluidic Cartridges

Developing microfluidic devices can be a daunting task not unlike the development of other medical or in-vitro diagnostic devices. Development typically arises from the need to miniaturize and automate existing assays for microbiological applications such as ELISA, PCR, flow cytometry, etc. This blog covers key considerations which we have found increase the chances of success […]

Designing BLDC motor drive electronics

Brushless, direct current (BLDC) motors are one of the options for motion control solutions in medical device development. BLDC motors typically offer higher power, higher efficiency, and lower wear than comparably sized motors of other types. The main challenge in incorporating these motors is the complexity in the drive electronics and control strategy. As an […]

3D Printed Parts Streamline Development Process

This blog provides a context for designers to streamline their development process using 3D printed parts as a part of their market-ready medical devices. 3D printing is disruptive. It challenges the way that designers consider product development. Contrasted with traditional fabrication methods, 3D printing offers several benefits along with certain limitations. Regulatory agencies are providing […]

What Does the Ideal Medtech Co-Op Look Like?

StarFish Medical hires many engineering students for medtech co-op positions in our product design department. A question I get asked a lot is: “what does the ideal medtech co-op look like to you?” The answer is complex and can vary. Everyone has their own strengths, but there are some general things that we look for […]

Choosing a Medical Device Camera Sensor

Medical Device Camera Sensor Resolution and Pixel Size Camera sensors are key components of video microscopes and endoscopes, fluorescence imagers, X-ray detectors, multiplexed detectors (i.e. detectors that measure/quantify more than one thing at a time), spectrometers, and imaging interferometers. With many options available and many specifications to consider, choosing a camera sensor for a medical […]

Optical Safety for Ophthalmic Instruments

This blog covers the optical safety limits and maximum exposure limits of wavelengths in the IR, UV and visible light spectrum for ophthalmic instruments. Optical safety for ophthalmic instruments focuses on ocular exposure limits because the eyes are the most light-sensitive part of the body and ophthalmic instruments are intended to interface directly with the […]

Strategies to Maximize Medical Device Optical Signals

A common challenge when designing medical devices that make optical measurements is ensuring the optical system state remains correlated with sensor measurements in order to maximize medical device optical signals. The sort of device I’m speaking of achieves its measurement by illuminating something and collecting the scattered or transmitted light. For this conversation, that “something” […]

Coupling Light from LEDs and Light Guides in Medical Devices

Moulded plastic light guides are an inexpensive means to “pipe” light around inside a medical device. Their design process makes light guides amenable to a variety of shapes and sizes.  Applications include delivering light to an indicator, a switch, or a peripheral diagnostic attachment, thus, these optical guides are an attractive technology for solving a […]
