Abstract
A cardiac assist device (1) with a cup element (2), an inner balloon element (5) and a tube element (6). The cup element (2) has a cup wall (2a), one or more in-flow openings (3), and an outflow element (4 having an aperture (4a). The inner balloon element (5) is positioned inside the cup element (2) free from the outflow element (4). The tube element (6) is arranged for inflating and deflating the inner balloon element (5) during operation. During operation in a pumping operational mode, the combination of first material, dimensions of the cup wall (2a), and dimensions of the outflow element (4) provides a containment force by the cup element (2) counteracting an outward directed force of the inner balloon element (5).
