Abstract:
A method of diverting fluid flow from a first vessel including an occlusion to a second vessel includes deploying a prosthesis at least partially in a fistula and making valves in the second vessel incompetent. Making the valves in the second vessel incompetent includes at least one of using a reverse valvulotome to cut the valves, inflating a balloon, expanding a stent, and lining the second vessel with a stent.

Claim (Index 2):
A method of modifying a vessel including covering collateral vessels of the vessel, the method comprising:\n forming a fistula between a first vessel and the vessel, wherein the first vessel is an artery and the vessel is a vein, wherein forming the fistula comprises:\n inserting a first catheter into the first vessel, the first catheter comprising a needle being configured to radially extend from the first catheter; \n inserting a second catheter into the vessel, the second catheter comprising an expandable device; and \n extending the needle from the first catheter, wherein extending the needle comprises:\n exiting the first vessel, \n traversing interstitial tissue between the first vessel and the vessel, \n entering the vessel, and \n puncturing the expandable device to confirm advancement of the needle into the vessel; \n \n advancing a guidewire from the first vessel, through the needle, and into the vessel; deploying a prosthesis at least partially in the fistula, wherein deploying the prosthesis comprises:\n tracking the prosthesis over the guidewire, and \n expanding the prosthesis with a balloon, \n wherein after deploying the prosthesis, blood is diverted from the first vessel to the vessel through the prosthesis; and \n making the valves in the vessel incompetent, wherein making the valves in the vessel incompetent comprises positioning a stent-graft in the vessel,\n wherein positioning the stent-graft in the vessel comprises covering the collateral vessels of the vessel, \n wherein the stent-graft is separate from the prosthesis, and \n wherein a proximal segment of the stent-graft longitudinally overlaps a distal segment of the prosthesis.
