1. A prosthesis delivery device comprising:
a pusher catheter having a proximal end, a distal end and a lumen extending there between;
a pusher extension extending proximally from the proximal end of the pusher catheter;
a tubular prosthesis releasably coupled to the pusher extension, wherein the tubular prosthesis comprises a main tubular body having a proximal end and a distal end and a tubular side arm extending from the main tubular body and wherein the distal end of the tubular prosthesis is adjacent to the proximal end of the pusher catheter;
wherein the pusher extension is external to the tubular prosthesis and extends along an external surface of the tubular prosthesis;
an extension dilator having a first end and a second end and a lumen extending between the first and second ends, wherein the extension dilator extends proximally from the proximal end of the pusher catheter, extends at least partially along the external surface of the main tubular body, into a distal end of the tubular side arm and exits a proximal end of the tubular prosthesis, and
a delivery sheath having a proximal end, a distal end and a lumen extending there between, wherein the sheath has a first position in which the proximal end of the sheath frictionally engages the extension dilator at a location proximal to a proximal end of the prosthesis, and a second position in which the sheath is retracted to a position distal to the proximal end of the prosthesis.
