Device same like our heart

Is it possible that we can make a device which works the same way our heart work? I just have some times crazy ideas popsup in my head. It just click in my head that why not we have a device which do the same function which our heart so that if some one heart fail we just switch it with the human made device.

It means science has limits and boundaries.

some of the boundaries are imposed by ethics, not science, including those that have to do with stem cells.

so we cannot change permanently any internal body part with a human made part.
Bones and teeth have been replaced successfully.
Bones and teeth and joints are pretty much static items.  Your heart beats are dynamically changing depending upon the oxygen levels required by the body. (the autonomic nervous system)

Artificial heart
From Wikipedia, the free encyclopedia
This article is about the mechanical device. For the Jonathan Coulton album, see Artificial Heart (album).

An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in case heart transplantation is impossible. Although other similar inventions preceded it going back to the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team including Willem Johan Kolff and Robert Jarvik.
An artificial heart is distinct from a ventricular assist device designed to support a failing heart. It is also distinct from a cardiopulmonary bypass machine, which is an external device used to provide the functions of both the heart and lungs and are only used for a few hours at a time, most commonly during cardiac surgery.

(near bottom of article)Frazier-Cohn[edit]
On 12 March 2011, an experimental artificial heart was implanted in 55-year-old Craig Lewis at The Texas Heart Institute in Houston by Drs. O. H. Frazier and William Cohn. The device is a combination of two modified HeartMate II pumps that is currently undergoing bovine trials.[46]
Frazier and Cohn are on the board of the BiVACOR company that develops an artificial heart.[47][48] BiVACOR has been tested as a replacement for a heart in a sheep.[49][50]
So far, only one person has benefitted from Frazier and Cohn's artificial heart. Craig Lewis was suffering from Amyloidosis in 2011 when his heart gave out and doctors pronounced that he had only 12 to 24 hours to live. After obtaining permission from his family, Frazier and Cohn replaced his heart with their device. Lewis survived for another 5 weeks after the operation; he eventually succumbed to liver and kidney failure due to his Amyloidosis, after which his family asked that his artificial heart be unplugged.[51]

Thank you guys. How nice is that if we can get our replaceable parts too from the junkyard. Lol
