Intracardiac pumping device
First Claim
1. An intracardiac pumping device for percutaneous insertion, comprising a pump connected at the proximal end with a catheter and at the suction-side distal end with a canula having inlet openings remote from the pump, characterized in that a flexible pigtail tip is provided at the canula distal of all of the inlet openings, wherein said flexible pigtail tip forms a spacer for keeping said inlet openings spaced apart from adjacent heart walls.

Abstract
The intracardiac pumping device has a pump (11) connected at its distal end (13) to a canula (15). At the distal end, the canula (15) has a suction head (16) for drawing blood. The suction head is extended by a non-sucking projection (20). The projection stabilizes the position of the pumping device in the heart. It extends the canula (15) mechanically without degrading the hydraulic conditions. It also serves as a spacer to prevent the suction head (16) from adhering to a wall of the heart.
