10 Sept 2015 Jahr - self regulating heart
Beschreibung:
In 2013, French Professor Alain Carpentier engineered the first self-regulating artificial heart, using biomaterials and electronic sensors. The device weighed 900g, was roughly the same size as a real heart and could imitate its functions exactly. In a 10-hour operation, it was successfully implanted within a 75-year-old patient at the Georges Pompidou European Hospital in Paris.Permanent artificial hearts had been around since 1982, with similar inventions that preceded them going back to the 1940s. Unlike previous versions, however, Carpentier's invention was the first to be completely artificial and self-regulating. Electronic sensors and microprocessors could monitor blood pressure and flow in real time – instantly adjusting the pulse rate – while a "pseudo-skin" made of biosynthetic, microporous materials could prevent blood clots, which had been a major issue in the past. By 2015, after a period of clinical trials, it is available within the European Union priced between 140,000 and 180,000 euros (about US$190,000 to $250,000).
