An implantable pump system is provided, including an implantable blood pump suitable for use as a partial support assist device, the system further including an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable pump. The implantable pump includes a flexible membrane coupled to an electromagnetic actuator including a magnetic assembly and electromagnetic assembly, so that when the electromagnetic assembly is energized, the electromagnetic assembly causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.

Described herein are devices and methods for pumping blood in a patient in need of circulatory assistance or a replacement heart. Instead of providing a temporary solution for these patients, the devices may be permanently implanted. The devices linearly reciprocate a shuttle within a housing to move blood into and out of the housing, and rotate the shuttle to selectively direct the movement of blood into and out of a plurality of ports in the housing.

So as to be able to determine the position of a functional element as precisely as possible during the invasive use of a blood pump in a patient's body without the use of imaging methods, the blood pump is connected to a main sensor which records signals of the patient's heart, which are compared to other electrophysiological heart signals recorded by several sensors distributed on the body surface so as to allow the position of the blood pump to be determined by way of linking.

An implantable pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable pump, an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable pump. The implantable pump includes a flexible membrane coupled to an actuator assembly that is magnetically engagable with electromagnetic coils, so that when the electromagnetic coils are energized, the actuator assembly causes wavelike undulations to propagate along the flexible membrane to propel blood from through the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.

A pumping system (200) for controlling the flow of interatrial blood comprises, housed inside a container (201), a control element (30, 30′, 30″) of the interatrial blood flow. The control element comprises: at least one worm screw (31), the rotation of which creates a two-way flow of interatrial blood; or a pair of counter-rotating propellers (31′); or a pair of membranes (31″) whose deformation creates a two-way flow of interatrial blood; or a flexible structure (31″) whose change in volume within the container (201) creates a two-way flow of interatrial blood.

An implantable cardiovascular blood pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable cardiovascular pump, an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable cardiovascular pump. The implantable cardiovascular blood pump includes a coaxial inflow cannula and outflow cannula in fluid communication with one another and with a pumping mechanism. The pumping mechanism may be a vibrating membrane pump which may include a flexible membrane coupled to an electromagnetic actuator assembly that causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable cardiovascular pump. The implantable cardiovascular pump may be programmed to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while avoiding thrombus formation, hemolysis and/or platelet activation.

A blood pumping device comprising at least a first pump and a second pump, and a first and second pump actuating means for inducing a blood flow in a body's circulatory system is disclosed. Each pump comprises one upper chamber having an inlet channel and one lower chamber having an outlet channel. The upper and lower chambers are separated by a movable valve plane provided with a valve. The pump actuating means are configured to apply a movement to said valve plane in an upward and downward direction between said upper and lower chambers in response to control signals from a control unit, such that when said valve plane moves in an upward direction the valve provided in the valve plane is in an open position allowing a flow of blood from the upper chamber to the lower chamber, and when the valve plane moves in a downward direction the valve is in the closed position and blood is ejected from the lower chamber through the outlet channel. The bottom part of the lower chamber is provided with a bag-like portion.
