Contract Manufacturing in the Medical Device Industry

Making medical devices differs from making other products. The paperwork is part of the product itself. A shop might meet your specs perfectly. But it is useless if it cannot make validated processes. It must also provide controlled documents. And it needs traceable records. These records must pass an FDA check or an ISO 13485 audit.

This guide shows what a medical device maker needs. It tells how to check one. It explains what a quality deal should have. It covers how validation and cost work. And it shows where plans often fail. This guide builds on our other help. That guide is about finding a maker for electronic products.

Legal responsibility does not transfer with the work. The legal manufacturer remains accountable for the device, so supplier controls, monitoring and records are your obligation, not a courtesy the shop performs for you.

Validation is a schedule item, not a formality. Plan three to six months between a frozen design and validated production for a moderately complex device, and longer where sterilization or biocompatibility testing is involved.

A regulated part will cost more. Expect its unit price to be 20 to 60 percent higher. This is true for the same part at the same volume. The extra cost is for papers, checks, and tracking. You cannot bargain away this cost.

Getting the design right saves money. Do this before it hits a regulated production line. This is the cheapest control you have. Our medical device design and development work builds papers as we design. We do not add them in later.

Design transfer moves a medical device design to production. It is a formal handover. This is a required part of design controls under 21 CFR 820.30(h).

Programs often fail here. This step turns engineering plans into procedures. It also creates fixtures, trained operators, and inspection records.

None of these things exist until someone writes them. Treat it as its own project phase. Give it a schedule and an owner. Do not see it as a week of emails after the design is final.

Once a device is in production, changes cost money. This is true under a quality system. A change to resin regrind percentage can cost money.

A new connector supplier can cost money. A moved supplier site can cost money. A changed fixture can cost money.

All these may need impact assessment. They may also need re-validation. Sometimes they need a new regulatory submission.

This is a big shock for teams. It hits teams from consumer hardware. There, a running change is a quick decision.

Get the design right first. Also, get its documents right. Do this before making a regulated product. This is the cheapest way to cut risk. See our product development process. And see our work in medical device design. We show how we manage that hand-off.

This means you pay someone else to make your medical device. Or you pay them to make its parts. This supplier must use a regulated quality system. An example is ISO 13485. The contract maker builds to your plans. They also make the records you need. These include validation and traceability records. The device file needs these.

Yes, in real life, this is true. Most legal makers need ISO 13485. This certification must cover your work. Notified bodies expect proof of supplier checks. You can use a shop without it. But you will need much more oversight. You will also need much more proof.

The legal manufacturer whose name is on the device remains responsible to regulators. Contractual remedies may recover cost from the supplier, but supplier qualification, monitoring and CAPA oversight remain the legal manufacturer's obligation.

A mid-level device takes three to six months to make. This is from a frozen design to full production. It includes IQ, OQ, PQ, and test method checks. Sterilization, biocompatibility, or software checks can make this much longer.

Unit prices typically run 20 to 60 percent higher than equivalent non-regulated parts, plus a validation programme and higher tooling and fixture cost. The premium buys documentation, inspection and traceability that the device file legally requires.

A quality agreement is only as good as the audit that preceded it. A first-article paper review is not an audit. Plan a two-day on-site with a lead auditor and a process engineer, and walk the actual line your device will run on rather than the demo cell near reception.

The findings that matter are rarely dramatic: an out-of-calibration torque driver, a training record without a signature, a nonconformance log with open items older than ninety days. Those are the leading indicators of the deviation that will eventually hold your lot.

Unique Device Identification looks like a labeling problem. But it is really a manufacturing problem. The device ID is set for each model.

Yet, the production ID changes. This includes lot, serial, expiration, and date of manufacture. You must make this ID on the production line.

You must check its barcode grade. You must match it to the device history record. Do this for every single unit.

Decide who handles GUDID submission. Decide who checks barcodes against ISO/IEC 15415 grade C or better. Also, decide what happens if a printer fails mid-lot. If you get this wrong, your device meets specs. But you cannot sell it.

The most costly part of a contract is often left unsaid. This is what happens when you stop working together. Get it in writing that you own the tooling.

Make sure you can take it back by a set date. Also confirm that checked process settings will transfer. And that inspection tools will move with it.

The maker must also help with the transfer. This is for a set time at agreed rates. Without these terms, your device has only one maker.

This is true even after eighteen months of checks. Every price hike after that is a fight you cannot win.
