A catheter system can include a tubular body, and at least one of a targeting system coupled to the tubular body, an expandable member, or a fluid injection port. A method of identifying a bifurcation can include inserting a catheter system into a first vessel, positioning the catheter system at a first location, expanding an expandable member to occlude the first vessel, delivering contrast material so the contrast material pooling proximate to the expandable member, and reviewing a shape of the contrast material in the first vessel under fluoroscopy.

Methods for routing a guidewire from a first vessel and through a second vessel in lower extremity vasculature

Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.

Devices and methods for increasing blood perfusion to a distal extremity

A device includes a first end portion, a second end portion, an intermediate portion, and a graft material. The first end portion has a first end diameter. The second end portion has a second end diameter smaller than the first end diameter. The first end portion comprises a first material. The second end portion comprises a second material different than the first material. The intermediate portion is between the first end portion and the second end portion. The intermediate portion tapers between the first end portion and the second end portion. The graft material is coupled to at least the intermediate portion.

Methods for targeting a body passage to effect fluid flow

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.
