A tiny heart pump inserted without surgery is being hailed as a revolutionary device for treating heart disease.

Called the Impella Recover LP 2.5 and made by Impella Cardiosystems of Germany, the four-millimeter-wide device sits in the left ventricle, the heart’s largest chamber, where it helps the heart pump blood.

Considered the world’s smallest heart support system, the pump is inserted through a tiny hole made in the artery in the groin. With the help of X-rays, it is guided by wires through the artery until it’s in the right place.

A patient at Hammersmith Hospitals NHS Trust recently became the first in the UK to get the pump, which was implanted for a day to provide temporary support following coronary artery bypass surgery.
