Abstract
A cardiac assist device includes a cup having a cup wall defining an inner cup volume, and an outflow element having an aperture for expelling a fluid during operation. A balloon has a balloon wall positioned inside the cup. A lumen is present for inflating and deflating the balloon during operation, creating a pumping operational mode and a filling operational mode, respectively. One or more one-way valves are arranged in the cup wall to allow the fluid to flow into the cup during the filling operational mode. One or more of the one-way valves comprise apertures and flaps arranged to close off the apertures during the pumping operational mode.
