In Brief Soft robotics and 3D printing have allowed a team of researchers from Switzerland to develop an artificial heart that works like the real thing. This proof of concept design was successfully tested in the lab, but it may take a while before it will be ready. <\/p>\n
Scientists have been developingartificial hearts for quite some time now. However, many of the current designs are unfortunatelyclunky, which presents difficulties in successfully integrating them into human tissue. To approach this issue, a team of researchers from ETH Zrich decided to take a cue from thebiological human heart. <\/p>\n
Instead of using separate parts, the Swiss team, led by Nicholas Cohrs, 3D-printed an artificial heart using a soft, flexible material. The material was molded into a single part (or a monoblock) which allowed the team to design a complex inner structure complete with pumping mechanisms able to be triggered by silicon ventricles. This method imitates a realistic human heartbeat. <\/p>\n
[O]ur goal is to develop an artificial heart that is roughly the same size as the patients own one and which imitates the human heart as closely as possible in form and function, Cohrs said in a press release. The team successfully tested this artificial heart, pumping blood-like fluid at human body-like pressures. The team published their research in the journal Artificial Organs. <\/p>\n
However, this design is still a proof of concept, which means its yet to be ready for actual implantation. The materials used are, as of right now, unable to last more than half an hour or some few thousand heartbeats, though that could vary a bit depending on a persons heart rate. Its a limitation the team will continue to work on, as new materials and design improvements advance. Once perfected, this design could potentially improve the lives and health ofaround 26 million people worldwide who suffer from various heart conditions. <\/p>\n
