Abstract

This embodiment suggests new approach for Endovascular Ventricular Assist Device, using the mathematical objective & principle of superposition allow design and calculation of the body response to VAD pump located in the Aorta. This new approach allows minimal invasive Endovascular VAD that result in similar relief to the heart as partial VAD. Using special power transfer technique will allow wireless power transformation into the aorta. This methods and technique should dramatic reduce VAD barrier

Claims

1. A treatment method comprising introducing, into the descending aorta, a mechanical pump whose electrical power source is wireless.

2. The method of claim 1 wherein the mechanical pump is introduced into by a non-surgical catheterization procedure

3. The method of claim 1 wherein the combination of one or more of the:

i) the mechanical and/or electrical properties of the pump; and

/or

ii) the location and/or orientation of the pump; and

/or

iii) the presence of one or more additional foreign objects within the aorta; and

/or

iv) the result of one or more aorta modification procedures to modify a shape of the aorta;

causes the rate of blood flow within the aorta to be substantially constant and/or substantially independent of the cardiac cycle.

4. The method of claim 1 further comprising introducing the additional foreign object(s) into the aorta.

5. The method of claim 4 wherein the foreign object is a stent and/or a balloon.

8. treatment method of claim 4 used as a preliminary temporal catheterization procedure treatment for very weak patients, then migrate from the EVAD using small belt/ring of power transmitter inject into the patient chest surrounding the aorta this replace the external belt After the patient recover with more robustness and power efficiency.

6. A treatment method comprising introducing one or more foreign object(s) into a host artery selected from the group consisting of the aorta, renal artery, and the femoral artery such that operation of the foreign object(s) within the host object causes the rate of blood flow within the aorta to be substantially constant and/or substantially independent of the cardiac cycle.

7. The treatment method of claim 6 wherein at least one of the foreign object(s) is a mechanical pump.

9. A kit for a Endovascular ventricular assist device (EVAD) comprising:

i) one axial flow pump

ii) a power harvesting receiver;

iii) an external power transfer belt;

iv) a mechanical fixation and blocking component

v) a controller unit;

Characterized in that said EVAD are configured to allow them to be implanted inside a blood vessel without surgery, and use wireless power harvesting.

10. A kit according to claim 9 wherein the fixing and or blocking in the aorta is using a balloon that covers the pump.

11. A kit according to claim 9 wherein the fixing and or blocking in the aorta is using a stent for fixation

12. A kit according to claim 9 wherein the fixing and or blocking in the aorta is using a stent for blocking and forcing the blood to path thru the pump only

13. A Kit according to claim 9 wherein the fixation method is use also as power harvesting receiver.

14. A Kit according to claim 11 wherein the stent is a weave stent that the receiver coil can use the stent wires for power harvesting

15. A Kit according to claim 11 wherein using multi layer stents, were the power harvesting is done using one stent and the fixation use another stent

16. A Kit according to claim 15 wherein those stents are inserted separately one after the other
