Automated Impella Controller Recalled Over Purge Flag Failure: Health Canada

Health Canada has classified a recall of Abiomed’s Automated Impella Controller (AIC) as a Type II health product recall, with the action dated August 18, 2026 and publicly listed on August 27, 2026. The recall was initiated by the manufacturer after an increase in complaints tied to purge cassette recognition problems traced back to a failing purge flag component inside the device’s purge pressure sensor assembly.

The AIC is used in hospitals to support Impella heart pumps, devices that provide temporary mechanical circulatory support for patients in cardiac distress. Because the purge flag helps the controller correctly recognize the purge disc, a failure in this small part can disrupt how the system monitors and manages the purge cassette during active patient support.

Products Affected by This Recall

The recall covers all units of the Automated Impella Controller (AIC) manufactured by Abiomed Inc., regardless of lot or serial number. Three catalogue numbers are listed as affected:

• Automated Impella Controller (AIC) – Model 0042-0040-CA, all lots
• Automated Impella Controller (AIC) – Model 0042-0000-US, all lots
• Automated Impella Controller (AIC) – Model 0042-0000-CA, all lots

Because the purge flag component is present in every AIC unit sold in Canada, the recall effectively touches the entire installed base of this controller model rather than a single production batch.

What Went Wrong?

According to Health Canada’s notice, the purge flag failures stem from two combined factors: a buildup of dextrose from a leaking purge cassette, and material embrittlement caused by normal usage, aging, or repeated exposure to cleaning chemicals. Abiomed has stated this is a usage-related issue rather than a manufacturing defect, meaning it can develop over time even in properly built units.

The practical impact, in most cases, is inconvenience for clinical staff, who may need to troubleshoot the device, attempt a purge cassette exchange, or swap out the AIC unit itself. If a purge flag failure happens before mechanical circulatory support has begun, it could delay a procedure, though Health Canada notes this is expected to remain ‘clinically manageable’ in most situations. The more serious scenario arises if the failure occurs during active Impella support or when there is an urgent need for circulatory assistance, in which case patients could experience a temporary period of inadequate hemodynamic support while the controller is being transitioned or replaced.

Who Is Affected?

This recall is directed at healthcare facilities and clinical staff who use the Automated Impella Controller, rather than individual consumers. Abiomed Inc., headquartered at 22 Cherry Hill Drive in Danvers, Massachusetts, is the company responsible for the device across Canada. Health Canada’s listing categorizes the issue under medical devices, specifically within the cardiovascular product category, and designates the intended audience as healthcare professionals.

Because the affected purge flag component is built into every manufactured AIC, hospitals and cardiac care units currently operating this controller model should treat the notice as applicable to their equipment, even without a specific lot number to check against.

What Should You Do?

Health Canada’s summary is direct: healthcare providers should contact the manufacturer if they require additional information. Rather than an immediate, blanket removal of devices from service, Abiomed has indicated that a prioritized, risk-based strategy will be used to manage component replacement, allowing the AIC to remain in use where needed to support continuity of patient care.

Clinical teams operating an AIC unit are encouraged to remain alert for purge cassette recognition issues and to have a plan in place for troubleshooting or exchanging a controller if a purge flag failure is suspected, particularly during active patient support.

Official Statement

Per the notice published by Health Canada, Abiomed described the situation as follows: the company ‘has initiated a voluntary medical device recall (removal) after identification of an increase in complaints related to purge cassette recognition issues due to the failure of the purge flag component of the purge pressure sensor assembly.’ The recall has been assigned identification number RA-82534 and is published under Health Canada’s medical devices recall program.
