It behooves designers to look at the assembly processes early, with a focus on how we can stop critical faults or those that are likely to happen. Process Failure Modes and Effects Analysis (PFMEA) is a tool to assess potential process failure points during assembly and how the failures could be felt or observed by […]

I was recently asked if I knew USP class VI is another standard that’s often quoted – the two standards are similar in some respects, but are not equivalent.
When developing a medical device, it’s easier both in time and effort not to reinvent the wheel. Sometimes, off-the-shelf (OTS, or COTS – commercial off the shelf) components don’t meet the device needs, and usually these deficiencies are obvious. The problem arises when we unconsciously ask for more than the original widget design requires.
“What’s the difference between production tooling vs prototype?” and “What quality can I expect?” are often questions that I get asked from development or clients. The best answer begins with other questions: “What quality do you really need?”, and “How many are you making?”
I once had an argument over a design given to me by an industrial designer. The design was difficult to manufacture, and I knew would cause some significant manufacturing challenges. There was one particular edge, one particular surface that would have been so much easier another way, but the designer was sticking to his guns. […]
We’ve become so used to stainless steels being stain-free, that we are shocked when we see rust on them. While the conditions required for stainless steel rusting are more likely to occur in medical lab equipment where stainless and salt solutions come together, it can happen in any device, including implants: A first thought is often […]
CAUTION: Overhead ahead One of the biggest mistakes start-up companies can make is underestimating manufacturing costs. The tendency is to focus on the cost of the components, i.e. Bill of Materials (BoM) costs. They’re important, but costs don’t stop at the BoM. Depending on the nature of the device, other/overhead charges can overshadow the costs of […]
Earlier this year, a colleague of mine at StarFish Medical wrote about when good is good enough: I’d like to expand on those comments regarding defining scope of work, adding that good enough can be great.
We prototype to learn, but also to communicate ideas and concepts. While undoubtedly 3D printing is an exceedingly useful tool, there are a number of low fidelity prototyping methods that can help launch a successful product. As medical device developers, we are often faced with making design decisions under tight budgetary constraints. Prototyping medical devices should […]
Garbage In, Garbage out… StarFish manufactures medical devices, and one of the coatings we see from time to time is anodizing. Anodizing creates a durable coating that can be a great coating for medical device parts. If aesthetics matter, it’s important not to think of anodizing in isolation, but also consider the inputs into anodizing.
Are we done yet? It’s a simple enough question. But the answers, like most questions, aren’t as easy. What is often missed in the translation is that there are varying degrees of done. In taking a medical device idea from concept through to manufacture there are a few ‘done’s along the way, and that takes time […]
