Abstract: A blood pump is disclosed. The blood pump apparatus is arranged to provide pulsatile flow, and comprises a flexible inner cylindrical duct providing a blood flow region, and an outer cylindrical duct arranged to surround the inner cylindrical duct and arranged to accommodate a pumping fluid. In the pump the inner cylindrical duct is described as comprising a blood inlet for receiving blood into the region, a blood outlet for passing blood out from the blood flow region and a passageway therebetween. There is also described the feature of the inner duct comprising a non return valve at the blood inlet and a non return valve at the blood outlet, the outer cylindrical duct having a fluid port for a pumping fluid, and a pump device arranged to cyclically deliver and withdraw pumping fluid to the fluid port thereby cyclically compressing and expanding the flexible inner cylindrical duct urging blood through the blood flow region and delivering a pulsating blood flow through the blood outlet.

Abstract: Membranes are provided to be specially developed for use in chambers for artificial circulatory assistance which may be employed primarily in cardiovascular procedures, notably to produce arterial capacitance, to regulate blood pressure, to produce aortic counterpulsation and to pump blood. The membrane may have circular sections that may vary in size or not depending on the function to be performed and are interconnected so that the transition between one section and the other is smooth, regardless of the size of each section. Further, chambers and pumps may be used for cardiopulmonary bypass and a pumping system.

Abstract: A blood component sampling cassette which can be more efficiently manufactured at lower cost as compared to a typical cassette, a blood sampling circuit set, and a blood component sampling system. A blood component sampling cassette (22) includes a cassette main body (23) made of a soft material to which heat sterilization is applicable. The cassette main body (23) is provided with a retransfusion line (44). The retransfusion line (44) is provided with a reservoir (47) configured to temporarily store a blood component to be returned to a blood donor. The reservoir (47) is pressed by a retransfusion pump (49) to discharge the blood component from the reservoir (47).

Abstract: A support system aimed at securing an assist device inside a patient's heart, the assist device comprising a pump inside a pump body and being in fluidic communication with an exit cylinder. The support system includes an upstream support element, aimed at securing the upstream extremity of the pump body to the patient's heart, a downstream support element, aimed at securing the exit cylinder to the patient's heart. The upstream support element and the downstream support element are two independent and autonomous functional elements, and the upstream support element and the downstream support element are aimed to removably secure the assist device inside the patient's heart.
