Recalled Product
Product Name: Impella 5.5 with SmartAssist
Product Code: 0550-0008
Product Serial Numbers: See Recall Database Entry
Distribution Dates: September 28, 2021 to March 6, 2023
Devices Recalled in the U.S.: 466
Date Initiated by Firm: April 17, 2023
Device Use
The Impella 5.5 with SmartAssist System is used for up to 14 days to support the pumping chambers of the heart (ventricles) when there is ongoing cardiogenic shock that occurs less than 48 hours after a severe heart attack (acute myocardial infarction), open-heart surgery, or when the heart is not functioning well due to a condition called cardiomyopathy.
Reason for Recall
Abiomed is recalling specific Impella 5.5 with SmartAssist sets after receiving customer complaints about purge fluid leaking from the purge sidearm of the pump. If a purge leak occurs the system will experience low purge pressures, prompting alarms and requiring evaluation. If the leak issue is not resolved, persistent low purge pressure and purge flow may lead to pump stop and loss of therapy. In patients who are critical, failure of the pump’s support can lead to further deterioration and worsening of their already critical condition and may even lead to serious injury or death.
Abiomed reports 179 complaints, three injuries and no deaths related to this recall.
Who May be Affected
People who receive ventricle and circulatory support from Impella 5.5 with SmartAssist.
Health care personnel providing care for people who receive support using the Impella 5.5 with SmartAssist.
What to Do
On April 17, 2023, Abiomed sent an Urgent Medical Device Recall letter to customers. The letter included the following recommended actions for customers and users:
- Examine inventory immediately to determine if you have product subject to this recall.
- Do not use affected products unless no other product is available.
- Contact Abiomed customer support to coordinate product return according to a scheduled date.

- A Codan Extension Tubing Set should be used to support delivery of sodium bicarbonate purge solution. For maximum effectiveness, the extension tubing set should be installed dry to the yellow Luer on the Impella 5.5 purge sidearm at the beginning of the case and should not be disconnected or replaced for the duration of the case.
- Purge cassette changes can be performed less frequently (purge cassettes have been tested with bicarbonate for 5 days).
