Robotic sleeve 'hugs' failing hearts

The sleeve - made of material that mimics heart muscle - hugs the outside of the heart and squeezes it, mimicking the action of cardiac muscle.

The early study, published inĀ Science Translational Medicine, shows the concept works on pig hearts.

The British Heart Foundation describes it as a "novel approach" that requires further trials.

'Synchronised movement'

Over half a million people in the UK have heart failure.
