A switchable pump device is provided and comprises a pump assembly including first and second pumps each having a separate inlet and outlet, an inner core or shell housing the pump assembly, and an outer shell housing the inner shell and having a pair of openings. The outer shell is interconnected to the inner shell such that the inner shell is movable relative to the outer shell to enable the inlet and outlet of a selected one of the first and second pumps to be aligned with the pair of openings in the outer shell to place the selected one of the first and second pumps in an operational condition while the other of the first and second pumps is positioned in an inoperative condition.

A circulatory support system may include a blood pump, one or more sensors, and a controller. The blood pump may include a driven component and a motor in communication with the driven component and the controller to drive the driven component to pump a blood flow through the blood pump. The controller may be configured to determine a command signal based on a value related to a speed of the motor, provide the command signal to the motor to drive the driven component, determine a value of a parameter related to operation of the blood pump based on the command signal and the value related to the speed of the motor, and output an indication a blood pump transition is recommended based on one or more determined values of one or more parameters related to operation of the blood pump.

The invention provides systems and methods for controlling the operation of intravascular catheters to treat fluid management disorders such as acute decompensated heart failure, chronic heart failure, ascites, lymphedema, chronic kidney disease, cardiac insufficiency, cardiac value regurgitation, or plural effusions. In particular, the invention provides a console, for use in a clinical setting, where the console controls operation of an intravascular catheter. The console includes a controller with treatment logic and a connected hub. The hub has a connection point to which an intravascular catheter can be connected. When the intravascular catheter is connected to the hub, the controller executes instructions and operates devices on the catheter to relieve the fluid management disorder.

A right cardiac assisting device to be percutaneously implanted inside a patient's heart, including an inlet, an outlet, a pump connecting the inlet to the outlet, and being designed to be located inside the right atrium or vena cava of the patient. The assisting device includes at least one support element configured to be secured to a first membrane of the patient's heart by passing through the first membrane, the first membrane separating the right atrium from the pulmonary artery of the patient's by passing through it. The support element tightly cooperates with the outlet to immobilize the pump, the inlet and the outlet inside the patient's heart and enable the patient's blood flow to be driven from the inlet to the outlet through the first membrane.
