Abstract

A medical device used in patients with inefficient heart function to improve the efficiency of the pumping action of the heart. This device adds one or more one-way valves in the blood vessels and/or arteries, very near, but not in, the heart, thereby increasing the efficiency of the native heart. The device includes one or more one-way heart valves designed to go in arteries/veins that are connected to the heart, and which arteries and/or veins are the conduits for taking blood into/out of the heart. The one-way heart valve allows blood flow in only one direction. An optional sleeve (stent) may be placed outside the arteries/veins where the valve(s) are located to add support to the walls. An optional sleeve (stent) may also be used on the inside of the artery to insure the artery does not collapse during a vacuum phase of the beating.

Claims

1. An apparatus comprising:

a one-way valve configured to be placed inside a vein that supplies blood to the heart of a patient through one or more surgical procedures, the valve configured to remain in place within the patient following the one or more surgical procedures, the valve configured to be placed upstream of the heart such that, when in place within the patient following the one or more surgical procedures, all portions of the valve and any components connected to the valve are disposed completely outside of any chamber of the heart, wherein the valve is configured to increase pumping efficiency of the heart,

the valve being configured to be placed at a distance of 10 inches or less away from the heart through the one or more surgical procedures; and

a sleeve configured to abut a portion of the vein between the valve and the heart through the one or more surgical procedures such that, when in place within the patient following the one or more surgical procedures, the sleeve mitigates expansion of the vein between the valve and the heart.

2. The apparatus of claim 1, wherein the one-way valve is configured to be placed within the superior vena cava and a second one-way valve is configured to be placed within the inferior vena cava through the one or more surgical procedures.

3. The apparatus of claim 1, wherein the one-way valve is configured to be placed upstream of the T junction where the superior vena cava meets the inferior vena cava through the one or more surgical procedures.

4. The apparatus of claim 1, wherein the valve is configured to be placed at least 1 millimeter away from the heart through the one or more surgical procedures.

5. The apparatus of claim 4, wherein the valve is configured to be placed within 20 millimeters of the heart through the one or more surgical procedures.

6. The apparatus of claim 4, wherein the sleeve is further positioned around a portion of the vein in which the one-way valve is situated.

7. The apparatus of claim 1, wherein the valve is configured to be placed in one or more of the pulmonary veins of the patient through the one or more surgical procedures.

8. The apparatus of claim 1, wherein no natural valve of the heart is removed when the valve is placed within the vein through the one or more surgical procedures.

11. The apparatus of claim 1, wherein the one-way valve is in fluid tight engagement with an interior surface of the vein when in place within the vein following the one or more surgical procedures.

9. An apparatus comprising:

one or more first one-way valves configured to be placed inside one or more veins that supply blood to the heart of a patient through one or more surgical procedures, the one or more first one-way valves configured to remain in place within the patient following the one or more surgical procedures, the one or more first one-way valves configured to be placed upstream of the heart such that, when in place within the patient following the one or more surgical procedures, each of the one or more first one-way valves are disposed at a distance of 10 inches or less away from the heart and all portions of the one or more first one-way valves and any components connected to the one or more first one-way valves are disposed completely outside of any chamber of the heart;

one or more second one-way valves configured to be situated inside one or more arteries that take blood from the heart through the one or more surgical procedures, the one or more second one-way valves configured to remain in place within the patient following the one or more surgical procedures, the one or more second one-way valves configured to be placed downstream of the heart such that, when in place within the patient following the one or more surgical procedures, each of the one or more second one-way valves are disposed at a distance of 10 inches or less away from the heart and all portions of the one or more second one-way valves and any components connected to the one or more second one-way valves are disposed completely outside of any chamber of the heart,

wherein the one or more first one-way valves and the one or more second one-way valves, when in place within the patient following the one or more surgical procedures, are devoid of any intermediary component that directly or indirectly secures any of the one or more first one-way valves to any of the one or more second one-way valves or to any other of the one or more first one-way valves.

10. The apparatus of claim 9, further comprising multiple first one-way valves, wherein each of the first one-way valves is configured to be placed within a different vein when in place within the patient through the one or more surgical procedures, and further comprising multiple second one-way valves, wherein each of the second one-way valves is configured to be placed within a different artery when in place within the patient through the one or more surgical procedures.
