Abstract
Described herein are improved blood pumping devices, including improved intra-aortic balloon pumps and ventricular assist devices. The pumping efficiency of either device may be improved with the use of one or more valves, counter pulsation balloons, non-compliant tubular structures, secondary pumping balloons, and similar components.
Claims21
An intra-aortic blood pump, comprising:
- an elongated catheter body;
- a first pumping balloon connected to the catheter body and configured to inflate and deflate via an inflation lumen within the catheter body;
- and,
- a first valve connected to the catheter body and configured to allow blood flow outside of the catheter body in a proximal direction and antegrade within a patient, and limit blood flow in a distal direction and retrograde within a patient.
1 more element
A method of pumping blood within a patient, comprising:
- inflating an intra-aortic balloon within an aorta of a patient;
- blocking blood flow in a retrograde direction of the aorta during the inflation of the intra-aortic balloon via a first valve.
