Pioneering surgery for angina patient

Pioneering surgery has given a man with angina a biodegradable stent to keep blood flowing through his arteries, without the need for metal implants.

For years patients suffering from angina have been treated with stents - tiny metal structures - that keep arteries clear and blood flowing.

Now, a new biodegradable stent has been produced.

It dissolves over time whilst releasing chemicals to lower the risk of the artery narrowing.

A bus driver from Leicestershire in the UK has received the treatment as part of an international trial- and won't have to undergo further treatment to have it removed.
