When Medical Devices Fail: Understanding Your Legal Rights

Posted on August 6, 2026

Medical technology has transformed healthcare. From surgical instruments to implanted devices, these tools help doctors diagnose illnesses, perform complex procedures and improve patient outcomes every day.

But when a medical device fails – or isn't as safe as patients are led to believe – the consequences can be life-changing. Infections, unexpected injuries and other serious complications have resulted in major lawsuits, raising important questions about who is responsible when medical technology doesn't work as intended.

When Medical Devices Cause Harm

Not every medical complication is the result of negligence. However, some injuries occur because of problems with the device itself, inadequate warnings, manufacturing defects or failures in how the equipment is maintained or used. As a result, patients may experience:

The Challenge of Reusable Medical Devices

Some of the greatest concerns involve reusable medical instruments. While these devices are designed to be cleaned and disinfected between patients, certain designs can make thorough cleaning difficult. Over time, worn seals, hidden crevices and trapped biological material may allow bacteria or other contaminants to remain on the device, even after recommended cleaning procedures have been followed.

One of the most well-known examples involved duodenoscopes, specialized instruments used during procedures involving the pancreas and bile ducts. Multiple outbreaks of serious infections prompted lawsuits and national attention after investigators found that the devices' complex design could make them difficult to disinfect completely.

These cases raised an important question: Was the problem caused by improper cleaning, or was the device itself designed in a way that made contamination more likely?

Who Is Responsible?

Determining liability isn't always straightforward. Depending on the circumstances, responsibility may fall on one or more parties, including:

In many cases, attorneys investigate whether the risks were known before patients were injured and whether appropriate warnings or design changes should have been made.

How Regulators Monitor Medical Device Safety

Medical devices are regulated and monitored after they enter the marketplace. Federal regulators track:

When similar injuries or infections are reported repeatedly involving the same device, investigators may determine that the problem reflects a predictable safety risk rather than an isolated incident. An important question often becomes: How quickly did the manufacturer respond after learning about the potential problem?

Why Documentation Matters

Medical device cases are built on evidence, not speculation. Important records may include:

These records can help connect a patient's injury to a specific medical device and establish whether similar problems had occurred previously.

During litigation, attorneys may also obtain internal company documents, engineering reports, safety notices and communications that reveal what manufacturers knew about potential risks and when they knew it.

When Should You Speak With an Attorney?

Not every medical complication leads to a legal claim. However, if you or a loved one experienced a serious infection, unexpected injury or other complication that may have been related to a medical device, it's worth asking questions. Consider reaching out to a top attorney for medical device injury in Philadelphia, who can help you understand your rights and evaluate your potential legal options. In the last few years, almost every teaching hospital in the city of Philadelphia has paid 8-figure verdicts and settlements to clients of Tom Duffy.
