Hemodynamic changes and right heart support during vertical displacement of the beating heart Eyal Porat, MD, Ram Sharony, MD, Simon Ivry, MD, Shigeyuki Ozaki, MD, Bart P Meyns, MD, PhD, Willem J Flameng, MD, PhD, Gideon Uretzky, MD The Annals of Thoracic Surgery Volume 69, Issue 4, Pages 1188-1191 (April 2000) DOI: 10.1016/S0003-4975(99)01437-X

Fig 1 Mode of insertion of the Enabler cardiac support system. The device expels blood from the right atrium into the main pulmonary artery. The Annals of Thoracic Surgery 2000 69, 1188-1191DOI: (10.1016/S0003-4975(99)01437-X)

Fig 2 Schematic cross section of the Enabler cardiac support system. Left, unloading phase; right, expelling phase. The Enabler consists of a pulsatile pump, a disposable head, and a cannula-valve unit. The pump comprises an electrohydraulically driven piston that forces fluid into and out of the head against a polyurethane membrane. This electrocardiogram (ECG)-triggered process generates a pulsatile blood flow through the cannula using a unique valve mechanism. (PA = pulmonary artery; RA = right atrium.)
