A system for generating a blood circulation in at least part of an organ of a vertebrate, including a first artificial cavity and a second artificial cavity. The cavities each include a flexible membrane capable of beating under the action of a gas. Each of the membranes separate in a sealed manner a blood circulation chamber and a chamber containing the gas. The system also includes: a first low pressure gas buffer reservoir; a second high-pressure gas buffer reservoir; a gas distribution; and a pneumatic pump.

An assembly for an extracorporeal life support system with a suction line that features a venous cannula and a pressure line that features an arterial cannula furthermore includes a pump that is arranged between the suction line and the pressure line. This assembly has a discharge line with a discharge cannula, wherein the discharge cannula is longer than the arterial cannula, and wherein the discharge line is connected to the suction line or the pressure line.

The present disclosure relates to an effluent bag for collecting accumulated blood treatment effluent. The effluent bag comprises a closeable effluent opening or connection to an exterior of the effluent bag. The disclosure further relates to methods, a blood treatment apparatus, and a discharge hose system.

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.

The present technology provides a blood pump device and associated systems and methods of use thereof to assist blood circulation in a patient. The blood pump device includes a flexible member disposed within a housing. Movement of the flexible member in the housing varies the volume of chambers within the housing and effectuates pumping of blood to and from a vessel in fluid connection with a chamber of the blood pump device.
