ABOUT THE AB5000™ Circulatory Support System
The AB5000 was FDA approved in September 2003 to provide temporary support for one or both sides of the natural heart in circumstances where the heart has failed, giving the patient's heart the opportunity to rest and potentially recover - and giving surgeons the therapeutic flexibility necessary to determine the best endpoint for treatment. The AB5000 and the BVS 5000 are the only devices approved by the FDA for the recovery of the natural heart.

The AB5000™ Ventricle, a major component of the AB5000™ Circulatory Support System, is a pneumatically driven blood pump. The sterile, disposable ventricle provides circulatory support in the presence of left-, right-, or both-sided heart failure. The Ventricle is located next to the body (paracorporeal) and can take over the pumping function of the natural heart. Assisted by vacuum, blood flows from the native heart into the AB5000™ Ventricle bladder. The bladder, which holds about 100 cc of blood, fills and empties much like the natural heart. Connection of the Ventricle to the patient is accomplished by connecting the pump to cannulae, or tubes, implanted in the patient's heart. These tubes pass through the patient's skin and connect directly to the AB5000 Console.

ABOUT BVS 5000
The BVS 5000 was approved by the FDA in 1992 as the first heart-assist device for use in patients who experience heart failure after heart surgery. It is the most widely used mechanical cardiac assist device for patients with a potentially recoverable heart. It is now available in more than 600 institutions throughout the world.

The BVS 5000 can support one or both sides of the failing heart. The BVS 5000 is designed to provide short-term support and recovery to the failing heart. The typical length of support on the BVS 5000 is approximately 7-10 days.

The disposable BVS Blood Pump is a pneumatically driven two-chambered device that supports one side of the heart. The BVS Blood Pump is placed external to the patient. The device takes over the pumping function of the heart to allow the heart to rest and potentially recover. The blood is re-routed from the heart to the pump and then back to the heart through its normal course of flow.
