Abstract
A catheter directionally conducts a pulsating body fluid and has a line segment defining an inner volume. A pump chamber section is arranged proximally as an extension of the line segment and defines a pump chamber having a frame therein accommodating a balloon. A first opening connects the inner volume to an external volume and a second opening is arranged proximally from the first opening to connect the inner volume to the external volume. A check valve is assigned to the second opening and the check valve includes a valve foil having an aperture formed therein offset from the second opening. A third opening communicates with the pump chamber. The frame is of a shape memory material which provides rigidity for a pulsatile operation of the balloon. During operation, the pulsating body fluid is conveyed in the inner volume directionally between the first and second opening by operating the balloon.
