Abstract:
1. An expandable stein, comprising: a plurality of first continuous substantially repeating patterns coursing along the stein in a helical manner and each consisting of a plurality of first circumferential segments alternating with a plurality of interconnecting constituents of the stent, the interconnecting constituents joining two or more other constituents of the stent, each first circumferential segment consisting of five linear struts connected to each other by four curved portions and being a contiguous element coursing in a circumferential manner about the stent and spanning between two interconnecting constituents; and a plurality of second continuous substantially repeating patterns coursing along the stent in a helical manner and each consisting of a plurality of second circumferential segments alternating with the plurality of interconnecting constituents, wherein the other constituents include first and second circumferential segments, each second circumferential segment consisting of three linear struts connected to each other by two curved portions and being a contiguous element coursing in a circumferential manner about the stent and spanning between two interconnecting constituents, wherein a plurality of the first circumferential segments are connected to a plurality of the second circumferential segments to define a plurality of adjacent cylindrical band-like elements, the cylindrical band-like elements being contiguous patterns forming cylinders around a longitudinal axis of the stent, and wherein two adjacent cylindrical band-like elements ate connected by only two interconnecting constituents.
