6.   The device also overcomes the limitations of implantable ventricular assist devices, which are often used in patients waiting for heart transplants.

7.   The pump, the MicroMed DeBakey VAD, is descended from a category of pumps called left ventricular assist devices, or LVADs.

8.   Another possibility is mechanical pumps, called left ventricular assist devices.

9.   Heart experts in the United States said some previous cases had been reported in which heart patients had a ventricular assist device removed because their own hearts had healed.

10.   Margulies said the heart tissue probably rebounded because the pump, called a left ventricular assist device, or LVAD, gave the heart a rest.
