Carmat SA: European Space technology leads to artificial heart development

Four test patients suffering from terminal cardiac failure will soon receive artificial hearts from the French company Carmat, now approved for human trials in France.

An artificial heart containing miniaturised space technology will soon beat inside a person, having now been approved for human trials in France.

With heart disease killing over 100 million people in developed countries alone and the demand for transplants far exceeding donations, creating a totally artificial heart has been the holy grail of cardiovascular medicine for half a century.

Brainchild of the visionary cardiac surgeon, Professor Alain Carpentier, the prosthetic is the result of 15 years of collaboration with aerospace giant Astrium, the space subsidiary of EADS.

In 2008, with support from the French Government and investors, Prof. Carpentier founded the EADS spin-off company, Carmat, to complete the work.

Combining the unique expertise of Prof. Carpentier, known worldwide for inventing today's most used heart valves, with Astrium's experience in building satellites, Carmat produced their first completely artificial heart earlier this year.

The Carmat-developed prosthetic heart has been developed utilising the expertise and technologies from European space programmes. 

In particular, the expertise in guaranteeing the extreme reliability of electronics on satellites helped the Carmat team to build a device that could withstand the tough conditions of the body’s circulatory system and pump 35 million times per year for at least five years without fail.

It turned out that space had the ingredients that Carmat needed. Working closely with satellite engineers, the company applied EADS Astrium's expertise in building spacecraft to guarantee the necessary precision and durability for an artificial human organ like a heart.

Fashioned in part from biological tissue and in part from miniature satellite equipment, the device combines the latest advances in medicine, biology, electronics and materials science to imitate a real heart.

The team had to build a device that could withstand the tough conditions of the body's circulatory system and pump 35 million times per year for at least five years without fail.

They needed the ultimate in reliability, and the answer came from design methodologies, testing strategies and know-how for the electronics on satellites.

"Space and the inside of your body have a lot in common," says Matthieu Dollon, Head of Business Development in EADS Astrium's French Elancourt Equipment team, who are working closely with Carmat on the heart.

"They both present harsh and inaccessible environments."

Telecom satellites are built to last 15 years on their own in space, 36 000 km above Earth. The heart might be closer than a satellite but it is just as inaccessible.

Visually Impaired Children Invited to Touch Space Technology - Astrium

A rather special event recently took place at Astrium’s Elancourt site just outside Paris, when a group of visually impaired youngsters were invited for a very hands-on visit of the plant, which specialises in the design and manufacture of electronic equipment for space rockets and satellites. Astrium attaches a great deal of importance to activities which reach out to the wider community in an endeavour to raise the profile of the space industry, explain how it works and what it contributes to the betterment of human lives. These activities seek to connect with a number of different audiences, from decision-makers to the ordinary man and woman in the street. Making contact with young people in an inclusive manner is a priority, since they are the space engineers and the politicians of the future. A big hit with the children was a ‘foam model’ of the Ariane 5 launcher, with which they could really get to grips, giving them a proper feel for the shape and constituent elements of the rocket. Its presence that day was serendipitous, a neat example of agile thinking on the part of Astrium’s Model Manager, who was called upon to provide mock-ups of a number of the company’s products to enliven the children’s visit. She realised that an unlikely object tucked away in a cupboard was just the thing. Read more here: Visually impaired youngsters invited for a hands-on visit of Astrium’s Elancourt site
