Johnson & Johnson Impella RP Heart Pump Recalls Raise Serious Patient Safety Concerns

FDA Class I Recalls Issued for Impella RP Devices After Sensor Malfunctions Lead to Injuries

FDA Finalizes Three Class I Recalls for Impella RP Heart Pumps

What Parker Waichman LLP Found

• The FDA classified all three Impella RP recalls as Class I, indicating a risk of serious injury or death.
• Malfunctioning differential pressure sensors may cause inaccurate clinical data displays.
• The issue has been linked to at least 22 patient injuries.
• Thousands of devices remain in use and require adherence to updated IFU guidance.
• Patients injured before updated warnings were implemented may have viable legal claims.

The U.S. Food and Drug Administration has finalized three Class I recalls involving Johnson & Johnson MedTech’s Impella RP, Impella RP with SmartAssist, and Impella RP Flex with SmartAssist heart pumps. A Class I recall is the most serious type of recall issued by the FDA. It is reserved for situations in which use of a device may cause serious injury or death.

These devices are used to provide temporary circulatory support for patients suffering from acute right heart failure. When a patient’s right ventricle cannot effectively pump blood to the lungs, rapid intervention is often required. The Impella RP system is inserted percutaneously and is intended to help maintain blood flow and stabilize the patient during a critical window of care.

According to the FDA, malfunctioning differential pressure (dP) sensors in these devices may cause inaccurate readings on the Automated Impella Controller (AIC). While the pumps may continue to function mechanically, inaccurate data displayed to clinicians can lead to incorrect clinical decisions. The FDA has linked this issue to 22 patient injuries. No deaths have been reported at this time.

A total of 4,496 Impella RP Flex with SmartAssist devices, 291 Impella RP with SmartAssist devices, and 179 Impella RP devices are included in these recalls.

Understanding the Differential Pressure Sensor Malfunction

At the center of these recalls is the malfunction of differential pressure sensors. These sensors measure pressure differences within the pump system and provide critical data to clinicians about device performance and patient hemodynamics.

The FDA has indicated that the dP sensors may “drift” over time. Sensor drift means that measurements gradually deviate from accurate values. When this occurs, the Automated Impella Controller may display incorrect flow rates or pressure data.

In critical care settings, clinicians rely heavily on real-time data to guide life-saving decisions. If displayed values are inaccurate, providers may:

• Adjust pump positioning unnecessarily
• Modify medication dosing
• Initiate additional invasive procedures
• Alter hemodynamic support strategies

Even if the pump itself continues to provide circulatory support, incorrect displayed data can influence clinical judgment in ways that expose patients to avoidable harm.

Johnson & Johnson MedTech has stated that the malfunction does not directly affect the pump’s ability to provide hemodynamic support. However, when medical decision-making depends on accurate information, faulty data can still create significant risk.

Why These Recalls Were Classified as Class I

The FDA previously warned the public about this issue in February, shortly after Johnson & Johnson MedTech issued an Urgent Medical Device Correction notice. At that time, the agency had not yet finalized recall classifications.

Now, the FDA has categorized the recalls as Class I. This designation means that continued use of the affected devices without carefully reviewing updated Instructions for Use (IFU) could result in serious injury or death.

Unlike many recalls, the devices are not being physically removed from hospitals. Instead, healthcare providers are being directed to review updated instructions and adjust their monitoring protocols accordingly. This type of recall can create complex questions about liability. Even if a device is not returned to the manufacturer, the existence of a Class I recall indicates that the risk is substantial.

Patients harmed before the updated guidance was implemented may have grounds to pursue compensation.

How Inaccurate Data Can Lead to Patient Injury

Right heart failure is a life-threatening condition. Patients who require Impella RP support are often in critical condition. Decisions regarding pump flow, positioning, and overall hemodynamic management are time-sensitive.

If a sudden change in displayed flow rate appears on the controller, clinicians may interpret it as:

• Pump displacement
• Reduced cardiac output
• Device malfunction
• Patient deterioration

The advisory specifically warns that abrupt changes in displayed flow should be compared against IFU guidance and clinical trends. However, in a fast-moving intensive care environment, reliance on inaccurate readings can lead to unnecessary repositioning of the device or additional invasive interventions.

Reported injuries associated with these recalls may involve complications from improper pump adjustments, additional procedures, or delays in appropriate treatment.

A Pattern of Recalls and Safety Alerts

The Impella platform has been the subject of multiple recalls and safety communications in recent months. In 2025 alone, issues involving the Automated Impella Controller resulted in recalls in July, September, October, and December. The FDA also recently announced a potential issue involving purge cassette leaks that remains under review.

Repeated recalls can raise serious concerns about quality control, product testing, and post-market surveillance. When multiple safety alerts occur within a short timeframe, patients and families may question whether earlier intervention could have prevented injury.

Johnson & Johnson acquired Abiomed, the original manufacturer of Impella devices, in 2022 for approximately $16.6 billion. In 2024, Abiomed began operating under the Johnson & Johnson MedTech name. Corporate acquisitions do not eliminate legal responsibility for defective medical devices placed into the marketplace.

Legal Rights of Patients Injured by Defective Heart Pumps

Medical device manufacturers have a legal duty to ensure their products are reasonably safe for intended use. When devices contain defective components or inadequate warnings, injured patients may pursue claims under product liability laws.

Potential legal claims may include:

• Defective design
• Manufacturing defect
• Failure to warn
• Negligent post-market monitoring

Compensation in these cases may cover medical expenses, additional surgical procedures, prolonged hospitalization, rehabilitation, lost income, long-term disability, and pain and suffering.

Because these devices are used in critical care settings, medical records, device logs, and controller data may play an important role in determining whether inaccurate sensor readings contributed to a patient’s injury.

Heart Pump Lawsuit FAQs

What is a Class I recall?
A Class I recall is the FDA’s most serious recall designation. It means there is a reasonable probability that use of the product will cause serious adverse health consequences or death.

If the device was not removed from the hospital, can I still file a lawsuit?
Yes. A recall does not need to involve physical removal for a claim to exist. If a device malfunction contributed to injury before corrective actions were fully implemented, legal rights may still apply.

How do I know if an Impella RP device was used during my treatment?
Hospital records, surgical reports, and device logs typically document the specific device used. An attorney can help obtain and review these records.

What types of injuries are linked to this recall?
The FDA has reported 22 patient injuries. These may involve complications from inaccurate data leading to unnecessary interventions, improper device adjustments, or treatment delays.

Who can be held responsible?
Liability may involve the manufacturer, depending on the nature of the defect. Each case requires careful evaluation of the device’s performance, warnings provided, and timing of safety communications.

How long do I have to file a claim?
Time limits vary by state. Acting promptly helps preserve medical evidence and ensures compliance with statutes of limitation.
