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 […]

Better brainstorming for medical device product development

This blog is about better brainstorming for medical device product development and includes using a systematic method of brainstorming that may help highlight higher quality concepts before detailed design begins. Brainstorming for medical device product development has previously been covered by former StarFish colleague, Boyd Allin.  I highly recommend you read that blog as well.

How to construct a custom differential screw

Understanding a differential screw and how to construct one I recently had to construct a custom differential screw when designing a precision test fixture for one of our medical device projects.  We used it to locate a test piece within +/-0.03mm. This motion required minimal force, and each part required a set of specific locating […]
