Jarvik-7 Artificial Heart
An artificial heart is a device that replaces the heart. Artificial hearts are typically used as a bridge to heart transplantation, but ongoing research aims to develop a device that could permanently replace the heart when a transplant—whether from a deceased human or, experimentally, from a genetically engineered pig—is unavailable or not viable. , there are two commercially available full artificial heart devices; both are intended for temporary use (less than a year) for patients with total heart failure who are awaiting a human heart transplant. Although other similar inventions preceded it from 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, William DeVries and Robert Jarvik. An artificial heart is distinct from a ventricular assist device (VAD; for either one or both of the ventricles, the heart's lower chambers), which may also be a permanent solution, or ...

Artificial Organ
An artificial organ is a human-made organ device or Tissue (biology), tissue that is Implant (medicine), implanted or integrated into a humaninterfacing with living tissueto replace a natural Organ (anatomy), organ, to duplicate or augment a specific function or functions so the patient may return to a normal life as soon as possible. The replaced function does not have to be related to life support, but it often is. For example, replacement bones and joints, such as those found in hip replacements, could also be considered artificial organs. Implied by definition, is that the device must not be continuously tethered to a stationary power supply or other stationary resources such as filters or chemical processing units. (Periodic rapid recharging of batteries, refilling of chemicals, and/or cleaning/replacing of filters would exclude a device from being called an artificial organ.) Thus, a Kidney dialysis, dialysis machine, while a very successful and critically important life sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
