The invention relates to an intercardiac pump device comprising a pump (11) whose distal end (13) is connected to a cannula (15) which is provided with a suction head (16) for sucking blood. Said strainer is provided with a non-sucking extension (20) for stabilising the position of said pump device in the heart and mechanically prolonging the cannula (15) without deteriorating hydraulic conditions. Said extension is also used in the form of a spacer in order to avoid that the suction head (16) adheres to a cardiac wall.

A method for providing a treatment recommendation to a physician for treating a patient is disclosed. The method comprises determining, from a processor in communication with a patient data repository, a first treatment recommendation based on a combination of selected patient demographics from the patient data repository applicable to the patient, and operational parameters of a plurality of ventricular assist devices (VADs) suitable for treating the patient, the first treatment recommendation having a first survival rate and comprising the use of a first VAD. The method then obtains a first signal from using the first VAD on the patient. The method then determines a second treatment recommendation based on the first signal and the first treatment recommendation, the second treatment recommendation having a second survival rate. The method then provides the second treatment recommendation to the physician if the second survival rate is higher than the first survival rate.

Apparatus and methods are described including a catheter, a first pump disposed on the catheter, and a second pump disposed on the catheter, proximally to the first pump. A control unit is configured to control activation of the first and second pumps. The first and second pumps are configured, when activated, to pump fluid in opposite directions from one another. Other applications are also described.

An intravascular blood pump (1) comprises a pumping device and a catheter (5). The pumping device comprises a drive shaft (12), a rotor (10) located at a distal end of the drive shaft (5), a housing (11), in which the rotor (10) is housed, and a distal bearing (14) for rotatably supporting a distal end of the rotor (10). The distal bearing (14) comprises a static support member (18), which protrudes into or up against the distal end of the rotor (10). The rotor (10) and housing (11) may be expandable, and the pin (19) may have a sufficient length to prevent disengagement of the pin (19) from the distal end of the rotor (10) when the rotor (10) and the housing (11) are in a collapsed state.

A circulatory support device includes a flexible cannula having a fluid outlet at a proximal end; and a pump assembly disposed at a distal end of the flexible cannula. The pump assembly includes a pump housing having a fluid inlet defined therein; a motor disposed within a distal end of the housing; and an impeller, driven to rotate by the motor, and configured to push blood toward the fluid outlet.

A heart pump is disclosed herein. The heart pump can include a cannula having one or more outlets. An impeller can be positioned in the cannula. The impeller can be configured to pump blood through the outlets along a longitudinal axis when the impeller is rotated at an operational speed. The heart pump can be configured to adjust an effective area of the outlets while the impeller is rotating or to provide relative motion between the cannula and the impeller along the longitudinal axis while the impeller is rotating.
