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.
