Abstract
A catheter assembly includes a coiled endoluminal prosthesis ( ) and a catheter ( ) having at least first and second telescoping shafts ( ). The prosthesis is releasably engaged to the distal ends ( ) 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 ( ) 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 ( ), in which one turn ( ) of the prosthesis has a greater pitch than the adjacent turns, at the intersection ( ) of a bifurcation within a blood vessel ( ). Remotely viewable marker elements ( ) may be used and include a marker element ( A, ) 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.
