Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. The pumping device of claim 1 , wherein the pigtail tip comprises a non-sucking projection. 3. The pumping device of claim 1 , wherein the pigtail tip comprises a hollow hose whose lumen is in communication with that of the canula. 4. The pumping device of claim 1 , wherein the inlet openings are provided in an expansible suction basket including an inflow funnel. 5. The pumping device of claim 1 , wherein the pigtail tip has an outer diameter that is smaller than that of the canula. 6. The pumping device of claim 1 , wherein the canula has a preformed bend. 7. The pumping device of claim 1 , wherein a guide wire is provided that leads through the pump and is adapted to be advanced from the canula into the pigtail tip. 8. The pumping device of claim 1 , wherein the pigtail tip has lateral auxiliary openings.
