Dr. William Ganz, who died on 10 November aged 90, was a pioneering cardiologist who co-invented a specialised catheter. In 1970, Dr. H.J.C. Swan and Ganz, who was born in Slovakia and moved to the US in 1966, invented a balloon-tipped catheter which measures heart function and blood flow in critically ill patients.

The Swan-Ganz Catheter is still used by physicians across the world.
