1. A prosthesis configured to support or expand a body passage, the prosthesis comprising:
- a plurality of annular members arranged in series along a longitudinal axis of the prosthesis such that each annular member is longitudinally adjacent another annular member, each annular member having a generally annular shape about the longitudinal axis, each annular member defining a first end and a second opposite end, an inside surface extending between the first end and the second end, and an outside surface extending between the first end and the second end, each annular member wrapped around the longitudinal axis to form an overlapping portion where a portion of the inside surface of the annular member is adjacent to a portion of the outside surface of the respective annular member to define a longitudinal lumen having openings at a distal end of the prosthesis and at a proximal end of the prosthesis;
each annular member being configured to expand and contract independent of the other annular members as the first end of an annular member moves towards the second end of the annular member and a length of the overlapping portion decreases; and
a graft extending between the plurality of annular members.

Abstract
A tubular prosthesis can be formed by rolling a sheet of material about a longitudinal axis, thereby forming a plurality of annular rings that can be arranged so as to be longitudinally adjacent one another, thus forming a tubular prosthesis. Each annular member can expand and contract independent of the other annular members. A graft material can extend between the plurality of annular members.

19. A method of making a prosthesis configured to support or expand a body passage, comprising:
-
providing a first generally flat sheet of material suitable for a graft; providing a plurality of flat strips of material suitable for a stent; positioning the plurality of strips in a lengthwise orientation so that each of the strips is generally parallel to one another; and rolling the strips simultaneously with the first sheet so that each strip and the first sheet form an approximately cylindrically shaped prosthesis in which a portion of each of the strips overlap each other to define an axially extending lumen. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
