A catheter assembly includes a coiled endoluminal prosthesis (

122, 190, 198

) and a catheter (

136

) having at least first and second telescoping shafts (

138, 140, 142

). The prosthesis is releasably engaged to the distal ends (

144, 146, 148

) of the telescoping shafts. The prosthesis is capable of assuming a second, expanded diameter state from a first, reduced diameter state. The length and number of turns (

128

) of the coiled prosthesis can be changed by the relative translation and rotation of the shafts. The catheter assembly is especially useful for placing a coiled stent graft (

122

), in which one turn (

132, 134

) of the prosthesis has a greater pitch than the adjacent turns, at the intersection (

184

) of a bifurcation within a blood vessel (

182

). Remotely viewable marker elements (

188, 190, 191, 192, 193, 195, 197

) may be used and include a marker element (

193, 190

A,

197

) configured to indicate orientation as well as axial position of the prosthesis. The ends of the prosthesis may be substantially less stiff than the remainder of the prosthesis and/or shaped to help prevent tissue trauma.
