摘要

在宾夕法尼亚州立大学，一个100cc大小的滚轴螺旋电动全人工心脏被植入IO动物体内;其中四只动物存活超过100天，一只动物活了205天。205天的动物。Agnes术前体重103公斤，植入205天后体重增加73公斤。在整个实验过程中，小牛都处于自动电子控制下，并且每周都能很好地耐受运动。动物死亡的原因是腐蚀碎片倒伏在转子和定子之间;这些腐蚀碎屑是由电动机堆产生的腐蚀。随后的实验利用涂层堆来消除腐蚀。

The Pennsylvania State University Roller Screw Electric Total Artificial Heart: 205 Days Survival In The Calf

A 100 cc size roller screw electric total artificial heart has been implanted in IO animals at The Pennsylvania State University; four of those animals have survived in excess of 100 days, with one animal living 205 days. The 205 day animal. Agnes, had a preoperative weight of 103 kg and gained 73 kgs over the 205 day implant duration. The calf was under automatic electronic control the entire duration of the experiment, and tolerated weekly exercise very well. The cause of death in the animal was corrosion debris lodging between the rotor and stator; this corrosion debris was corrosion generated by the electric motor stack. Subsequent experiments utilize a coated stack to eliminate corrosion.
