With the heart pump you can make the heart of a ,extinct, dead animal specimen beat outside the body even when the animal is still dead ,as long as the heart is not badly decomposed. To operate the machine you must take out the animal's heart and use plastic tubes to act as bloodstreams to circulate blood through the body and turning on all the internal organs making the body function again. If preformed correctly the animal will come back to life. The animal's body will function as long as the pump is running. When the pump turns off the animal once again falls dead. I hope this invention will help in the reanimation of extinct species in the future as much as any invention of a citizen of Tomorrowland.
