Patent ID: 7722663

Claim:
An endoluminal prosthesis comprising: a proximal end, a distal end and a hollow tubular body having a central longitudinal axis, the body comprising a stent scaffold of helically wound undulating wires having alternating peaks and valleys to define turns thereat; the hollow tubular body comprising at least one segment of curvature along a portion of a longitudinal length of the body, wherein the central longitudinal axis of the body is curved along said portion of the longitudinal length of the body throughout the segment of curvature; the segment of curvature comprising an inside of the curvature and an outside of the curvature; wherein the wires and their turns are distributed substantially equally and uniformly displaced along the length of the prosthesis, including being distributed substantially equally and uniformly displaced along the length of the segment of curvature, to provide a constant pitch of the wires therealong.
