Carmat shares skyrocket after receiving CE marking

Shares in heart prosthesis maker Carmat skyrocketed on Thursday a day after the French manufacturer received CE marking.

The CE marking - which indicates a product is made to European Economic Area (EEA) standards - allows Carmat to market its total artificial heart in the European Union as a bridge to transplants.

Carmat shares were up 46% at 0829 GMT in their biggest daily gain in nine years.
