1. A method of installing a tubular prosthesis through a sidewall of a native lumenal vessel, comprising:
providing a prosthesis having:
a distal annular flange configured to help seat the prosthesis when it is pulled proximally;
a distal tubular segment extending proximally from the distal flange that has sufficient stiffness to maintain a puncture in an open condition that is formed through a first vessel wall through which the distal segment passes; and
a proximal tubular segment that is sufficiently stiff to seat within and urge against a second vessel wall;
wherein the prosthesis includes at least one marker that is visible from outside the patient using an imaging modality, wherein the at least one marker of the prosthesis includes radiopaque material or iron oxide;
collapsing the prosthesis onto a delivery system, wherein the delivery system includes at least one marker that is visible from outside the patient using the imaging modality, wherein the at least one marker of the delivery system includes radiopaque material or iron oxide;
delivering a distal end of the delivery system to an opening defined through a native lumenal vessel wall;
deploying the distal annular flange inside of the native lumenal vessel wall; and
maintaining the at least one marker of the prosthesis and the at least one marker of the delivery system in registration with each other during at least a portion of the method.
