-
a web structure defining an essentially tubular body expandable from a contracted configuration to an expanded configuration; a plurality of longitudinally adjacent web rings defining the web structure; and a plurality of sequentially adjoined web elements defining the web rings, the web elements being disposed substantially parallel to a longitudinal axis of the essentially tubular body when in the contracted configuration, pairs of the web elements being sequentially adjoined at junction bends, wherein a first junction bend in a first web ring is connected to a second junction bend in a second web ring by a connector having a first strut and a second strut, the first strut and second strut being essentially parallel one to the other with a space between at least a portion of the first strut and the second strut, wherein at least a first foot extension joins the first to the second struts, wherein the first foot extension includes a first member extending from the first strut and providing a sole portion of the first foot extension, and a second member interposed between the sole portion and the second strut and providing the toe portion of the first foot extension, wherein the sole portion has an essentially rectilinear shape and the toe portion has an essentially arcuate shape, and wherein a third foot extension protrudes from the first junction bend and couples the first web ring to the connector. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
