AbioCor AbioCor is the name of the most current artificial heart developed by the organization ABIOMED and its supporting colleague the National Heart, Lung and Blood Institution. This new model is unlike the previous artificial heart (Syncardia) in that it is self-contained; this means that the patient is not attached to machines or monitors via tubes connecting to the device. AbioCor was designed specifically for patients with end-stage heart failure who were unfit for a heart transplant, other treatments and had a life expectancy of 30 days or less. The first AbioCor artificial heart implant surgery occurred in 2001. The patient's name was Robert Tools, he was a 59 year old man who survived without a living heart for 151 days before passing away due to abdominal bleeding and a stroke. AbioCor's structure contains two artificial ventricles, a hydraulic pumping system, and an internal rechargeable batter via an external power source. It is also equipped with an internal controller implanted in the abdominal area of the patient that monitors and controls the artificial heart's pumping speed. AbioCor is powered by the external battery carried by the patient who with the aid of a transcutaneous energy transmission ( TET), transfers energy wireless to the artificial heart. In addition, each external battery pack only lasts up to 4 hours. Incase the external battery is not with the patient, the artificial heart will then switch its power source to the internal battery which can maintain AbioCor working for 20 minutes.
