1. A circulatory support device for an in-vivo heart, said in-vivo heart including an aortic valve and a pulmonary valve, comprising:
a pump-holder configured such that it can be disposed intracardially in a left and/or right ventricular outflow tract of the heart via a catheter, wherein the pump-holder comprises and anchor that can be removeably fixed in a subcommissural triangle underneath the aortic valve and the pulmonary valve, respectively in a blood flow direction on a ventricular side of the aortic valve and the pulmonary valve, respectively, a pump configured such that it can be removeably fixed in the pump-holder via a catheter, wherein the pump is one of: (a) releasably disposable in the pump-holder after the pump-holder has been anchored in the subcommissural triangles underneath the aortic valve and (b) fixedly connected to the anchor. |
