Japanese researchers have developed a wirelessly controlled mechanical heart pump, moving a step closer to developing a fully embedded artificial heart.
According to reports, the newly developed pump is about the size of a size C battery and can pump over 5 liters a minute of blood, which is similar to a human heart, by spinning a cylindrical magnet.
The pump can be driven by simply using a separate device over the skin to generate a magnetic force.
Traditional mechanical pumping systems are too large to be embedded in the human body and need to be connected to an electrical cord routed through a patient's skin.
Owing to the new pump's small size and simple structure, an artificial heart using the pump will be less costly, professor Kazushi Ishiyama, who has led the research group said.
