PCT No. PCT/EP98/01868 Sec. 371 Date Dec. 2, 1998 Sec. 102(e) Date Dec. 2, 1998 PCT Filed Mar. 31, 1998 PCT Pub. No. WO98/43689 PCT Pub. Date Oct. 8, 1998The pump device comprises a first pump (10a) that may have its intake side inserted into the left ventricle (42) of the heart, while the delivery side is located in the aorta (40), and a second pump (10b) having its intake side arranged in the right atrium (43), whereas its delivery side is in the pulmonary artery (47). A common control unit drives both pumps in mutual dependance, the first pump (10a) taking the lead function, whereas the second pump (10b) pumps only about 90% of the volume flow of the first pump (10a). Pressure sensors at the pumps serve to determine the differential pressure between the intake side and the delivery side of a pump and to determine the volume flow. Both pumps are inserted into the heart without having to open the ventricles.
