Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone. Most recalls are Class II or III.
Brand Name: HeartMate Product Name: HeartMate 3 Controller (Standalone) Model/Catalog Number: 106531US, HeartMate 3 Controller, US; 106531INT, HeartMate 3 Controller, OUS; 106531LF2, HeartMate 3 Low Flow 2.0 Controller Software Version: N/A Product Description: The HeartMate 3" System Controller acts as the central power and communication hub for the HeartMate 3 LVAS. It passes power from the Power Module, the Mobile Power Unit, Lithium-Ion Batteries, or its own integrated emergency backup supply, down to the LVAD via the Driveline. The HeartMate 3 System Controller constantly monitors system performance through communication with the implanted LVAD and Controller internal measurements and alerts the user to any alarm conditions by activating membrane panel LEDs and integrated audio annunciators. Further information on alarm conditions as well as system status can be attained by the user from the front panel LCD on the System Controller. When connected to a HeartMate Touch" Communication System, the System Controller sends information regarding the System Controller and Pump Status once per second to provide additional information to the user. This link also allows the clinician to set new patient operating parameters (e.g. pump speed) and provides a link for downloading trend and/or event recorder data. Component: Yes, HeartMate 3 LVAS
Why it was recalled
Due to potential corrosion issues associated with the Backup Battery cable connector that may cause a Backup Battery Fault Alarm.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
