Artificial heart ready for human trials.
French company CARMAT have announced that their artificial heart is scheduled to be implanted into patients in four medical centers around the world. The device completely replaces the patient’s original heart.
The artificial heart consists of two cavities, mimicking the organ’s ventricles, which are separated by a moving membrane that’s hydraulically powered via a special actioning fluid. This membrane reproduces the action of the ventricular wall during contractions, creating blood flow in and out of the device. The system is works in conjunctions with sensors and a microcontroller that continuously adjust the activity of the prosthesis to match the needs of the patient.

Supermarket terminal lets you choose your own music to shop to.
New Zealand supermarket Pak ‘N Save is installing the touch terminals at all of its 50 locations, allowing customers to que up music from the supermarkets own database to play while shopping. To avoid misuse of the system, once a song has been selected it can’t be replayed for a couple of hours.
Retailers have been accused by psychologists of pumping out high-tempo music to encourage impulse purchases.
But Jules Lloyd, brand director at Pak ‘n Save’s parent company Foodstuffs, said research showed customers were happier shopping when they were listening to their favourite music.
“And we are all about giving our customers the best experience whilst in store.”
