The man who wears his heart on his back (packed safely in a rusksack)

When Matthew Green leaves hospital, the one thing he really mustn’t forget is his rucksack.
The father of one will be carrying part of his new heart in it.Mr Green, 40, will be the first Briton to be discharged from hospital with a completely artificial heart.The device in his chest is slightly larger than the organ it replaces and weighs less than six ounces.

Around 900 of the ‘bridge-to-transplant’ devices have been fitted around the world, although Mr Green is the first to receive one in the UK.He had been in a critical condition after developing a chronic heart condition and no suitable donors could be found. With his health deteriorating fast, doctors at Papworth Hospital in Cambridgeshire decided to fit him with the device in a £100,000 operation
