Five Critical Considerations in Designing Microfluidic Cartridges

Microfluidic cartridge fluidic testing
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 during the early phases of microfluidic cartridge development.

Five Applications Using Microfluidic Machine Learning

Microfluidic cartridge prototype
Microfluidics is a powerful tool on its own, but over the past years, the combination of microfluidics and Machine Learning (ML) has enabled microfluidic technologies to push into new areas and applications. Microfluidics is a fluid handling technique which takes place inside micro-channels or pathways using nano/microliter volumes. It has been used in many applications particularly in miniaturizing laboratory processes and procedures.

What Will You Do First When COVID is Under Control?

When COVID is Under Control
Summer is (almost) officially here. Vaccinations are up and lock downs are loosening as regions reach herd immunity levels. We’ve been working remotely for over a year, so it seemed like a good time to test StarFish culture. Yes, there is a consensus. Read on and see if you agree with our employee choices for their first activities when COVID is under control and COVID restrictions are lifted.

Designing BLDC motor drive electronics

Designing BLDC motor drive electronics

Quick experiment driving a brushless motor using the “smooth max” drive waveform

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 example, we recently developed the Winnipeg Ventilator 2.0, which uses a BLDC motor at its core.

Pathways to a FDA Approved or Cleared Medical Device

Chutes and Ladders –

FDA Approved or Cleared Medical DeviceCommercializing your medical device in the US market requires submitting marketing applications to the FDA to become an FDA Approved or Cleared Medical Device. The content of your FDA submission is determined by how your medical device is classified into one of three Classes (I, II, or II), based on the degree of risk it presents. If your product falls into the Class I/II exemptions, it will only require device registration and listing with FDA. For Class II and III devices, there are several pathways to market.

3D Printed Parts Streamline Development Process

3D Printed Parts Streamline DevelopmentThis 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 guidance to 3D printed component testing and process control, which allows for 3D printed parts to be included in medical devices once they are defined by the manufacturer.

What Does the Ideal Medtech Co-Op Look Like?

Medtech Co-Op
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 across different families of skills and characteristics. Keeping in mind that it’s never a ‘one size fits all’ situation, here is what I say to someone who asks me what the ideal medtech co-op looks like:

Choosing a Medical Device Camera Sensor

Medical Device Camera Sensor Resolution and Pixel Size

Medical Device Camera Sensor
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 device can be a daunting task. This blog series covers technical trade-offs to consider when incorporating a visible or near-infrared range camera sensor into a medical device.

Optical Safety for Ophthalmic Instruments

Optical Safety for Ophthalmic InstrumentsThis 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 eyes during diagnosis and treatments.

Strategies to Maximize Medical Device Optical Signals

Maximize Medical Device Optical SignalsA 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” could be part of a patient, or maybe an assay involving a sample from a patient.

Coupling Light from LEDs and Light Guides in Medical Devices

Coupling Light from LEDs and Light GuidesMoulded 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 light-transport problem in a medical device.
