Abstract
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.

10. An intracardiac pumping device for percutaneous insertion comprising:
-
a pump configured to be positioned within the vasculature of a patient, the pump comprising; a motor, and a pump housing and impeller positioned distal of the motor and mechanically coupled to the motor; a cannula positioned distal of the pump housing, the cannula comprising a distal suction head having inlet openings; a catheter having a distal end that operably extends to the motor and permits an electrical lead to pass into contact with the motor so that the impeller is rotatably driven by the motor, and a proximal end configured to extend the electrical lead to a controller located outside the patient; and a flexible atraumatic projection extending distally from a distal end of the suction head. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
