The Emergency System Operation (ESO) mode may not provide adequate patient support under a specific operating condition.

Abiomed notified customers via an Urgent - Voluntary Medical Device Field Removal Notice on May 8, 2009 advising users that the Emergency System Operation (ESO) mode may not provide adequate patient support under a specific operating condition. The letter stated that customers may continue to support patients with the AB Portable Driver during the process since the failure has not occurred during patient support. An Abiomed Field Service Engineer will contact customers and arrange for a temporary exchange for the affected driver with a corrected driver. The firm recommends that customers switch the patient to hand pump support and switch patient to backup driver until they can confirm that the Driver(s) has been corrected by an Abiomed Field Service. Questions are to be directed to Michael O'Hara at 978-646-1543 or a Field Service at 800-554-8666.
