The heart printed on the 3D printer is beating like the present
Artificial heart, as a rule, is a device the size of a washing machine, which you can use only when you are near on a hospital bed. Recently appeared compact mechanical, but alas, imperfect implants, which have certain drawbacks.
A group of scientists from the Higher Technical School of Zurich has developed an artificial heart made of soft silicone that beats practically like the present and provides a safe blood supply. It is intended for patients waiting for transplantation of the donor heart and those whose heart is recovering from the disease. About the relevance of the transplant is indicated by the fact that only in the US its turn for transplantation is expected by about 3,000 people.
Scientists are constantly looking for new solutions to improve existing artificial hearts. Especially it concerns the search for more biocompatible materials, such as, for example, silicone foam.
Artificial heart in size is the same as the present and weighs 390 grams. It was created by the method of 3D printing and casting according to the prepared model. The heart has a right and left ventricle, separated from the chamber, imitating the heart muscle, which pumps blood with compressed air.
It is worth mentioning that while the capabilities of the device are limited to about 3000 hits within 30-45 minutes. And yet the team is confident in the correctness of the chosen concept. The results of the research show that creating a full-fledged artificial heart is not such a distant prospect.
