A heart pump for infants that can be used during surgery has been developed by researchers at Purdue University in the US.

The viscous impeller pump is designed for treating infants with univentricular circulation, a congenital heart disease that usually requires three open heart surgeries, performed over a period of months or years, to correct.

However the pump allows the cardiologist to perform all the three heart surgeries at the same time.

It works by assisting the heart during surgery and can be delivered through a catheter, without the need for open heart surgery.

The pump can also be used to temporarily treating adults with the disease.

The researchers have received a four-year grant of $2.1m from the National Institutes of Health’s National Heart, Lung and Blood Institute to continue developing the pump.
