If your heart fails, Danvers, Mass.-based Abiomed (ABMD) says that it has the tools to take over the pumping function. The medical device maker, which makes blood pumps, catheters and sensors, recently got one of its products approved -- the Impella 2.5 -- and analysts and Abiomed are hoping that this tool will be the key to the company's success. The Impella 2.5 is supposed to take over all the heart's pumping activity after a heart failure. By doing this, blood can continue to flow throughout the body while the heart rests and heals. The Impella 2.5 can pump 2.5 liters of blood flow per minute -- about half of what the heart pumps. That makes it a useful product for procedures, such as an angioplasty, by enhancing the blood flow during the procedure, thereby reducing the chances of any damage being done to the heart.
