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.
