Abstract:
A catheter devices/systems and methods therefrom are described herein for treating acute kidney injury, especially the contrast-induced acute kidney injury wherein the devices may prevent the contrast dyes from entering into kidney and/or facilitate blood flow of kidney by said catheter system.

Claim (Index 21):
A method of preventing acute kidney injury from contrast agent introduced into vasculature of a subject, the method comprising:\n positioning a proximal portion of a catheter device comprising a catheter shaft and an occlusive element in an abdominal aorta of the subject adjacent renal artery ostia of the subject, wherein one or more longitudinal position indication features are disposed on the occlusive element; deploying the occlusive element of the catheter device to occlude the renal artery ostia; confirming occlusion of the renal artery ostia when the occlusive element is deployed by observing the appearance of the one or more longitudinal position indication features; introducing a bolus of the contrast agent into the abdominal aorta of the subject while the occlusive element is deployed to occlude the renal artery ostia, thereby preventing the contrast agent from entering into renal arteries of the subject; and collapsing the occlusive element after the bolus of the contrast agent has been introduced, thereby allowing blood flow to the renal arteries to resume.
