SynCardia is a company based in Tucson, Arizona which currently has two separate models available. It is available in a 70cc and 50cc size. The 70 cc is used for biventricular heart failure in adult men, while the 50cc is for children and women. As good results with the TAH as a bridge to heart transplant accumulated, a trial of the CardioWest TAH (developed from the Jarvik 7 and now marketed as the Syncardia TAH) was initiated in 1993 and completed in 2002. The SynCardia was first approved for use in 2004 by the US Food and Drug Administration.
