Medical device claims face a hurdle that most product cases do not: federal preemption. A device that injures a patient raises the ordinary product liability questions of defect and causation, but before any of that, the threshold issue is often whether federal law allows the state claim to proceed at all. The answer turns on how the device was approved by the Food and Drug Administration, and the distinction can be the difference between a viable claim and one barred at the outset. That approval framework, and the preemption that flows from it, is where any defective device claim begins.
Where Medical Device Claims Begin
At base, an injury from a defective medical device fits the product liability framework: the device may carry a manufacturing defect, a design defect, or a failure to warn, and the same questions of defect and causation apply. Implants, surgical devices, and similar products can all give rise to claims. What makes the device setting different from an ordinary product is the layer of federal regulation that sits on top, which can sharply limit which claims survive.
FDA Approval: PMA Versus 510(k)
The pivotal fact in a device case is usually how the FDA cleared the device for market, because two pathways carry very different legal consequences:
| Premarket Approval (PMA) | 510(k) Clearance | |
|---|---|---|
| Process | Rigorous, device-specific safety and effectiveness review | Showing substantial equivalence to an existing device |
| Class | Typically Class III, higher-risk devices | Often Class II devices |
| Effect on claims | Broad federal preemption | Generally no preemption |
Which pathway applied to a given device frequently determines how much room a state-law claim has.
How FDA Preemption Limits Claims
In Riegel v. Medtronic, the U.S. Supreme Court held that the federal Medical Device Amendments expressly preempt state tort claims challenging the safety or effectiveness of a device that received premarket approval, to the extent the claim would impose requirements “different from, or in addition to” the federal ones. That can bar claims like strict liability, design negligence, and warning defects for a PMA device. By contrast, in an earlier decision the Court held that devices cleared through the less rigorous 510(k) process do not receive that preemption, because that process does not impose device-specific federal requirements. So a 510(k) device generally leaves the full range of product liability theories available, while a PMA device does not.
The Parallel-Claims Exception
Preemption of PMA devices is broad but not total. A narrow “parallel-claims” exception allows a state claim to proceed where the same conduct that violates a state-law duty also violates a specific federal requirement, so the claim imposes nothing different from or in addition to federal law. The strongest example is a manufacturing-defect claim alleging the device departed from its FDA-approved specifications, since that turns on federal compliance rather than challenging the approved design. These claims must be pleaded with particularity, identifying the specific federal violation. A separate line of cases holds that claims premised on fraud against the FDA are themselves impliedly preempted.
Learned Intermediary and Recalls
Even where a device claim can proceed, the warning analysis usually runs through the learned intermediary doctrine, under which the manufacturer’s duty is to warn the implanting or prescribing physician rather than the patient directly. A device recall, as with vehicles, can be evidence that a defect existed but is not by itself a finding of liability. Both points sit within the larger preemption question that governs whether the claim survives at all.
Frequently Asked Questions
Why might a medical device claim be barred?
If the device received FDA premarket approval (PMA), federal law may expressly preempt state claims that would impose requirements different from or in addition to the federal ones, as the Supreme Court held in Riegel v. Medtronic.
Does preemption apply to every device?
No. Devices cleared through the 510(k) substantial-equivalence process generally are not preempted, leaving the full range of product liability theories available. The approval pathway is often decisive.
Is there any claim against a PMA device?
Possibly. A narrow parallel-claims exception allows a claim where the conduct violates both a state duty and a specific federal requirement, most often a manufacturing-defect claim that the device departed from FDA-approved specifications, pleaded with particularity.
Who must be warned about a device’s risks?
Under the learned intermediary doctrine, the manufacturer’s duty generally runs to the implanting or prescribing physician rather than to the patient directly.
