Abstract
A renal stent includes a balloon expandable segment intended for deployment in the renal vessel and a self expanding segment intended for deployment in the aortic segment. One or both of the balloon expandable and self expanding segments can be deployed in the ostial region of the renal vessel, typically the renal artery. The balloon expandable segment provides superior radial strength for maintaining dilated diameter of the renal vessel. The self expanding segment expands to conform to the flared ostial and aortic regions of the vessel. The self expanding segment can be balloon dilated to enhance conformance of the self expanding stented segment to the ostial and aortic regions.
