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 method of treating a patient having a body, blood, and a descending aorta, comprising:

introducing a pump into the patient'"'"'s descending aorta;

powering the introduced pump wirelessly by use of a power transfer belt disposed external to the patient'"'"'s body; and

using the wirelessly-powered introduced pump to move the patient'"'"'s blood through the descending aorta at a substantially constant rate.

2. The method of claim 1 wherein the introducing step comprises using a catheterization procedure to introduce the pump into the patient'"'"'s descending aorta.

3. The method of claim 1 wherein the pump is wirelessly powered.

4. The method of claim 1 wherein the pump is an axial flow pump.
