Abiomed Impella Controller Purge Cassette Injury and Death Lawsuit Lawyers

Purge cassette recognition failures involving Automated Impella Controllers may delay or interrupt critical mechanical circulatory support for seriously ill cardiac patients.

What Parker Waichman LLP Found

• The FDA identified the Automated Impella Controller purge cassette recognition problem as a potentially high-risk medical device issue.
• Abiomed reported 37 serious injuries and three deaths associated with the issue as of August 17, 2026.
• A purge flag failure may delay the start of mechanical circulatory support or require an urgent controller exchange during active support.
• All Automated Impella Controller units globally are within the scope of Abiomed’s phased removal action.
• Patients injured during Impella treatment may need medical records, device identification information, and equipment records preserved to determine whether the controller issue contributed to their injuries.

Patients who require an Impella heart pump are often facing a severe cardiovascular emergency or undergoing a high-risk cardiac procedure. In these situations, reliable mechanical circulatory support can be critical. A malfunction involving the equipment controlling that support can create an especially dangerous situation because there may be very little margin for delay or interruption.

The U.S. Food and Drug Administration has issued an Early Alert concerning Automated Impella Controllers manufactured by Abiomed after reports of purge cassette recognition problems involving a component known as the purge flag. According to the FDA, failures involving this component can prevent the controller from properly recognizing that the purge disc has been inserted.

The consequences can extend beyond an equipment alarm. A failure occurring before mechanical circulatory support begins can delay the procedure and potentially leave an unstable patient without needed circulatory support for longer than intended. A failure during active Impella support may require clinicians to exchange the Automated Impella Controller.

The FDA reported that, as of August 17, 2026, Abiomed had reported 37 serious injuries and three deaths associated with the issue.

Abiomed has recommended that affected Automated Impella Controllers be removed from locations where they are used or sold as part of a phased removal process. Hospitals may continue using their existing inventory while awaiting replacement in order to maintain continuity of patient care.

For patients who suffered serious injuries and families who lost loved ones following an Impella controller problem, the FDA Early Alert raises important questions about what occurred, whether a controller malfunction contributed to the outcome, and whether a product liability or wrongful death claim should be investigated.

What Is the FDA Warning About Abiomed Automated Impella Controllers?

The FDA Early Alert concerns the Automated Impella Controller, commonly referred to as the AIC. The controller serves as the primary interface clinicians use to operate an Impella Catheter.

The controller performs several important functions. It controls the performance of the Impella Catheter, monitors the system for alarms, and provides information about the position of the catheter across the patient’s aortic valve.

The current problem involves the purge pressure sensor assembly inside the controller. More specifically, the FDA identified failures involving a component called the purge flag.

The purge flag interacts with the purge disc and allows the Automated Impella Controller to determine whether the purge disc has been inserted correctly. When the purge flag component fails, the controller may be unable to properly recognize the purge cassette.

The affected U.S. products identified by the FDA are:

• Impella Controller, Packaged, US, Product Code 0042-0000-US, UDI-DI 00813502010022;
• Impella Optical Controller, Packaged, US, Product Code 0042-0010-US, UDI-DI 00813502010985; and
• Optical, AIC, Impella Controller, Pkgd, US, Product Code 0042-0040-US, UDI-DI 00813502011401.

The FDA states that all Automated Impella Controller units globally are within the scope of Abiomed’s removal action. Abiomed is implementing the removal in phases and replacing the purge flag and purge retainer components located within the controller’s purge pressure sensor assembly.

This distinction is important for patients reviewing their medical records. The safety issue does not necessarily concern the implanted or inserted Impella Catheter itself. It involves the controller used to operate and monitor the Impella system.

Why Is the Automated Impella Controller Purge Flag Failure Dangerous?

The seriousness of the problem becomes clearer when considering the medical condition of the patients who rely on Impella mechanical circulatory support.

Impella devices can be used in patients whose hearts cannot adequately maintain circulation on their own or during certain high-risk cardiac procedures. These patients may already be hemodynamically unstable. Their blood pressure, cardiac output, and organ perfusion may depend partly upon continued mechanical circulatory support.

A controller problem that might merely be inconvenient with another type of medical equipment can therefore become medically urgent in this setting.

The FDA describes two principal scenarios.

The first can occur while clinicians are setting up a procedure. When the purge flag component fails during setup, the Automated Impella Controller can display a “Purge Disc Disconnected” alarm.

Clinicians are instructed to reinsert the purge disc. If reinserting it does not resolve the alarm, they are instructed to switch to a backup Automated Impella Controller.

That process takes time.

For a stable patient, a short delay may be manageable. For a patient experiencing severe cardiovascular instability, however, delaying mechanical circulatory support could potentially have serious consequences.

The FDA specifically warns that when a failure occurs before support begins, the resulting procedural delay may cause a hemodynamically unstable patient to experience a prolonged period without mechanical circulatory support.

That distinction may become critical when evaluating a potential injury claim. Attorneys investigating these incidents may need to reconstruct exactly when the malfunction occurred, the patient’s cardiovascular condition immediately beforehand, how long mechanical support was delayed, and what medical deterioration occurred during that period.

What Can Happen if the Controller Fails During Active Impella Support?

The second scenario is potentially even more concerning because it involves a patient who is already receiving Impella support.

According to the FDA, a purge flag component failure occurring during hemodynamic support can produce a “Purge Disc not Detected” alarm.

Clinicians are again instructed to reinsert the purge disc. If that fails to clear the alarm, a backup Automated Impella Controller should be used.

A failure during active support may occur during an elective purge cassette exchange, although the FDA explains that it may also occur during ongoing support.

Mechanical circulatory support can continue temporarily while purge delivery has stopped and clinicians prepare for an AIC exchange. Nevertheless, replacing the controller becomes urgent.

Medical personnel may need to stabilize the patient before briefly interrupting support while the controller is exchanged.

For patients who are already critically ill, even a brief disruption can raise substantial concerns. The relevant question following an injury is not simply whether the device eventually resumed functioning. Investigators may need to determine whether the controller malfunction caused or contributed to cardiovascular deterioration, organ damage, cardiac arrest, neurological injury, or another adverse outcome.

37 Serious Injuries and Three Deaths Reported in Connection With the Issue

The reported adverse outcomes make the FDA Early Alert particularly significant. According to the FDA, as of August 17, 2026, Abiomed had reported 37 serious injuries and three deaths associated with the purge flag component issue.

An association does not by itself establish that a controller defect legally or medically caused every reported injury or death. Each incident requires individual investigation.

Nevertheless, the number and severity of reported events make it important for patients and families to determine whether an Automated Impella Controller was involved when an unexpected complication occurred during Impella treatment.

A patient may never have known the model of controller being used. In an intensive care unit, cardiac catheterization laboratory, or operating room, patients and their families generally rely entirely upon healthcare providers and medical equipment manufacturers.

That means medical records can become central evidence.

Hospital records may document alarms, equipment exchanges, procedural delays, hemodynamic changes, cardiac events, and communications concerning equipment failures. Separate hospital biomedical engineering or equipment-management records may contain additional information about the controller that never appears in the patient’s ordinary chart.

Why Abiomed Is Removing Automated Impella Controllers

Abiomed is addressing the problem by replacing two components within the purge pressure sensor assembly: the purge flag and purge retainer.

The company sent affected customers a letter on August 12 advising them of the problem and recommended actions. According to the FDA, the phased removal encompasses all Automated Impella Controllers globally.

Abiomed’s field service personnel are expected to contact facilities and coordinate the return of identified controllers so that the specified components can be replaced.

Hospitals are not being told simply to stop using every Automated Impella Controller immediately. The FDA explains that existing hospital inventory can continue to be used while facilities await service from Abiomed because maintaining access to the equipment is necessary for continuity of patient care.

That creates an unusual but important distinction. A device can present a potentially serious safety concern while also performing a function so medically important that removing every controller simultaneously could itself endanger patients who require mechanical circulatory support.

Facilities therefore need to recognize alarms quickly, maintain access to backup controllers, and follow the manufacturer’s instructions while affected units move through the replacement process.

Injuries That May Require Investigation Following an Impella Controller Failure

Not every complication experienced during Impella treatment is caused by the controller. Patients receiving this type of treatment often have severe underlying cardiovascular disease, and complications can occur even when every device functions correctly.

A potential claim therefore requires careful medical and factual analysis.

When a documented controller malfunction coincides with an unexpected deterioration, attorneys may investigate injuries including:

• cardiac arrest or severe cardiovascular deterioration;
• hypoxic or anoxic brain injury caused by inadequate circulation or oxygen delivery;
• stroke or neurological injury;
• kidney, liver or other organ damage related to inadequate perfusion;
• additional emergency procedures or prolonged hospitalization;
• complications associated with interruption or delay of mechanical circulatory support;
• permanent disability; and
• death.

Causation is often one of the most contested issues in medical device litigation. Manufacturers may argue that the patient’s underlying cardiac disease caused the adverse outcome rather than the equipment failure.

Medical records, device data, timing evidence, and testimony from qualified medical and engineering professionals can therefore become critical in determining what happened.

Potential Impella Controller Product Liability Lawsuits

Patients who were seriously injured because of an allegedly defective medical device may have grounds to pursue a product liability claim. Families may also have wrongful death claims when a device defect caused or contributed to a patient’s death.

The precise claims available depend upon applicable state law and the evidence.

A product liability investigation may consider whether the controller contained a design or manufacturing defect, whether adequate warnings were provided, when the manufacturer became aware of the problem, whether adverse event information revealed a developing safety signal, and whether reasonable corrective measures were taken.

Our attorneys may also examine whether a facility received the manufacturer’s safety communication, when it received that communication and what actions were taken afterward.

The existence of an FDA Early Alert does not automatically establish liability. Likewise, an injury occurring while an Impella system was being used does not automatically establish that the controller caused the injury.

The purpose of an investigation is to connect the evidence: identifying the device, documenting the malfunction, establishing the patient’s condition before and after the failure, and determining whether the malfunction caused or materially contributed to the injury.

Abiomed Impella Controller Lawsuit FAQs

Is the Automated Impella Controller currently recalled?

The FDA issued an Early Alert on August 26, 2026, concerning the purge cassette recognition issue. An Early Alert is used to inform the public about actions involving potentially high-risk medical device issues while the FDA continues reviewing information. Abiomed has recommended removal of affected Automated Impella Controllers through a phased process. Patients should therefore avoid describing the current FDA action as a finalized recall determination unless the FDA subsequently updates its classification.

What problem is affecting the Automated Impella Controller?

The issue involves failures of the purge flag component inside the purge pressure sensor assembly. The purge flag helps the controller recognize whether the purge disc is properly inserted. Failure can generate a “Purge Disc Disconnected” or “Purge Disc not Detected” alarm and may require replacement of the Automated Impella Controller.

How many injuries and deaths have been reported?

As of August 17, 2026, Abiomed had reported 37 serious injuries and three deaths associated with the issue, according to the FDA. These reports do not automatically prove that the controller caused each injury or death. Individual cases must be investigated to determine whether a controller malfunction contributed to the patient’s outcome.

Can I file an Impella controller lawsuit if I suffered a serious injury?

Potentially. A patient may have a product liability claim if evidence establishes that a defective controller caused or contributed to serious injuries. An investigation may examine device identification records, alarms, controller exchanges, medical records, maintenance records, and the timing of the patient’s deterioration. Applicable legal claims and filing deadlines depend upon state law and the circumstances of the case.

Can a family file a wrongful death lawsuit?

When evidence establishes that a defective medical device caused or contributed to a patient’s death, surviving family members or the estate may potentially pursue a wrongful death or survival claim under applicable state law. Recoverable damages and the individuals legally entitled to bring the claim vary by jurisdiction.

What should I do if I believe an Impella controller malfunction injured me?

Patients should obtain and preserve their medical records and any information identifying the Impella equipment involved. Because important evidence may also exist in hospital equipment records, device logs, and maintenance records, an attorney can investigate whether the affected controller can be identified and whether records document alarms, exchanges, or interruptions in mechanical circulatory support. Legal deadlines can apply even while federal regulators continue investigating the device issue.
