3. 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.)
