Claim Text:
1. A stent comprising: a first wire configured into a non-woven first longitudinal tube having a first helical pattern and comprising a proximal portion and a distal portion, and a lumen extending between the proximal portion and the distal portion, wherein the first longitudinal tube is outwardly biased to assume an expanded configuration; and a second wire configured into a non-woven second longitudinal tube having a second helical pattern and comprising a proximal portion and a distal portion, and a lumen extending between the proximal portion and the distal portion, wherein the second longitudinal tube is inwardly biased to assume a compressed configuration; wherein the first helical pattern of the first longitudinal tube is opposite to the second helical pattern of the second longitudinal tube; wherein the second longitudinal tube is disposed about at least a portion of the first longitudinal tube in a non-woven manner; and wherein the outwardly bias of the first longitudinal tube and the inwardly bias of the second longitudinal tube combine to form a mechanically stable assembled stent that is expandable from a compressed delivery configuration to an expanded deployed configuration.
