Who’s Responsible When a Medical Device Fails?

When a medical device fails, liability may fall on manufacturers, designers, hospitals, or doctors depending on how and why the failure occurred.

who is responsible when a medical device fails

Quick Answer: When a medical device fails, responsibility may fall on the manufacturer, designer, distributor, hospital, or even multiple parties, depending on whether the failure was caused by a design defect, manufacturing error, inadequate warnings, or improper handling.

Medical devices are intended to improve or save lives, but when they malfunction, the consequences can be severe and permanent. These cases raise complex legal questions because injuries often stem from decisions made long before a device ever reached a patient.

This article examines how courts determine responsibility when a medical device fails, the legal theories involved, and what injured patients should know about potential claims.

Why Medical Device Failures Lead to Legal Claims

Medical device failures differ from ordinary accidents because they often involve products implanted in the human body or relied upon for critical treatment. When a device breaks, migrates, degrades, or malfunctions, patients may face additional surgeries, long-term complications, or life-threatening injuries.

From a legal standpoint, the central issue is not simply that a device failed, but why it failed and who had the duty to prevent that failure.

Who can be held liable?

The Manufacturer

Primary Responsibility in Most Cases

In many medical device lawsuits, the manufacturer is the primary defendant. Manufacturers have a legal duty to ensure their devices are reasonably safe when used as intended.

Claims against manufacturers often involve:

Defective design, where the device is inherently unsafe
Manufacturing defects, where something went wrong during production
Failure to warn, where known risks were not adequately disclosed

If a device was prone to breaking, degrading, or causing injury under normal use, courts frequently focus on whether the manufacturer could have designed or tested the product differently.

Designers and Engineers

When the Problem Starts on the Drawing Board

Sometimes the root of a device failure lies in its design rather than how it was made. In these cases, responsibility may extend to the designers or engineering teams involved in development.

Design defect claims may arise when:

The device behaves unpredictably once implanted
Materials interact poorly with the human body
Safer alternative designs were available but not used

Courts examine whether the risks outweighed the benefits at the time the device was released.

Distributors and Suppliers

Liability Along the Supply Chain

Medical devices pass through multiple hands before reaching a patient. Distributors, suppliers, and sometimes retailers can share responsibility if they sold or supplied a defective device.

These parties may be liable if they:

Distributed a device they knew, or should have known, was defective
Failed to pass along safety warnings or recall notices
Mishandled or improperly stored the device

Liability depends on their role and level of knowledge in the distribution process.

Hospitals and Healthcare Facilities

Limited but Important Responsibility

Hospitals are generally not responsible for design defects, but they may be liable in certain circumstances, such as when they:

Used a recalled or expired device
Failed to follow safety protocols or manufacturer instructions
Improperly stored or handled the device

Hospitals may also face claims if they ignored known risks associated with a particular device.

Doctors and Surgeons

Malpractice vs. Product Liability

Physicians are usually not responsible for device defects, but they can be liable under medical malpractice law if their actions contributed to the injury.

This may include:

Improper implantation or placement
Using a device in a way inconsistent with medical standards
Failing to inform patients of known device risks

These cases are often pursued separately from product liability claims against manufacturers.

Shared Liability

When Multiple Parties Are at Fault

Medical device failure cases frequently involve shared liability. It is common for lawsuits to name multiple defendants, especially when injuries result from a combination of design flaws, inadequate warnings, and improper use.

Courts allocate responsibility based on each party’s role in causing the harm.

Compensatory and Punitive Damages in Medical Device Failure Claims

When liability is established, injured patients may pursue compensatory damages, which are intended to cover:

Medical expenses and future treatment
Lost income and reduced earning capacity
Pain, suffering, and loss of quality of life

In more serious cases, punitive damages may also be available. These are awarded when a defendant’s conduct is found to be reckless or showed a conscious disregard for patient safety, such as ignoring known risks or suppressing safety data.

Punitive damages are rare, but when awarded, they signal that the failure involved more than an honest mistake.

How These Cases Are Typically Handled

Large-scale medical device failures often result in mass tort litigation, where similar claims are coordinated in multidistrict litigation (MDL) in a federal court. This allows courts to manage complex evidence efficiently while preserving individual claims.

Smaller or highly individualized cases may proceed independently under state law.

Examples of Major Medical Device Lawsuits That Changed Patient Safety

Some of the largest medical device lawsuits in recent history involved Bard PowerPort implants, hernia mesh products, and Exactech joint replacements.

In each case, patients trusted devices that were meant to improve their health, only to suffer serious complications that led to surgeries, long-term pain, and financial hardship. In these lawsuits, evidence showed that manufacturers knew about risks but failed to properly warn doctors and patients, which ultimately led to widespread litigation and compensation for those harmed.

Bard PowerPort Lawsuits

The Bard PowerPort is an implantable port used to deliver medications such as chemotherapy directly into the bloodstream. While effective for some patients, many reported that the device cracked, fractured, or leaked chemicals into their bodies after implantation.

When the port failed, patients experienced infections, blood clots, chemical exposure, and damage to surrounding tissue, often requiring emergency removal surgery. Lawsuits allege that patients were never warned about the risk of material degradation, even as reports of failures continued to rise.

Hernia Mesh Complications and Lawsuits

Hernia mesh is used to reinforce weakened tissue during hernia repair surgery, but thousands of patients later experienced serious complications. Common issues included chronic pain, infections, bowel obstruction, mesh migration, and hernia recurrence.

Investigations revealed that some mesh products were made from materials unsafe for long-term implantation. As complications mounted, multiple hernia mesh products were recalled, leading to tens of thousands of lawsuits and over $1 billion in settlements paid by manufacturers.

Exactech Joint Replacement Lawsuits

Exactech manufactured hip, knee, and ankle replacement devices that were later found to have been packaged in defective bags. These faulty packaging materials allowed oxygen exposure, which caused the implants to degrade long before their expected lifespan.

Patients experienced premature joint failure, severe pain, inflammation, and loss of mobility, often requiring painful revision surgery. Lawsuits claim Exactech failed to disclose the packaging defect for years, leaving patients unaware that their joint replacements were at risk of early failure.

Legal Takeaway

When a medical device fails, responsibility is rarely limited to one party. Courts look closely at design decisions, testing, warnings, and how the device moved through the healthcare system.

For injured patients, understanding who may be legally responsible is the first step toward determining whether a valid claim exists.
