Abstract:
1. An expandable stent, consisting of: a plurality of adjacent closed cylindrical bands, the closed cylindrical bands being contiguous patterns forming cylinders around the stent longitudinal axis, connected to one another by a plurality of interconnecting constituents of the stent, the interconnecting constituents joining two or more other constituents of the stent, wherein the other constituents comprise the adjacent closed cylindrical bands; and first and second end segments straddling a main body of the stent, each closed cylindrical band including a plurality of first circumferential segments, each first circumferential segment being a contiguous element coursing in a circumferential manner about the stent and spanning between exactly two interconnecting constituents and consisting of five linear segments connected with end portions; each closed cylindrical band including a plurality of second circumferential segments, each second circumferential segment being a contiguous element coursing in a circumferential manner about the stent and spanning between exactly two interconnecting constituents and consisting of three linear segments connected by end portions; the first and second circumferential segments alternating with one another in each closed cylindrical band; wherein the first circumferential segments of adjacent closed cylindrical bands are offset from each other to form a first continuous substantially repeating path coursing along the stent in a helical manner and consisting of a plurality of the first circumferential segments alternating with a plurality of the interconnecting constituents; and wherein the second circumferential segments of adjacent closed cylindrical bands are offset from each other to form a second continuous substantially repeating path coursing along the stent in a helical manner and consisting of a plurality of second circumferential segments alternating with a plurality of the interconnecting constituents.
