Abstract
Intravascular devices are delivered to the aorta percutaneously via the femoral artery. The devices are anchored within the vasculature in the region of the renal artery ostia. These embodiments function to increase the flow of blood from the aorta to the renal arteries, thus delivering a higher relative percentage of the blood flowing through the aorta to the kidneys. The elevation in blood low to the kidneys improves the natural removal of excess fluids from the body. In one embodiment, the device is a diverter element positionable upstream of the renal artery ostia. In another embodiment, the device is a flow restrictor positionable downstream of the ostia to cause an elevation is pressure upstream of the ostia.
