Abstract:
1. A circumferentially nested scissor stent being expandable from a collapsed state to an expanded state, the stent comprising a tubular member having longitudinal and circumferential axes, the tubular member comprising: at least one linkage section being disposed along the circumferential axis, the linkage section comprising at least one structural element, the structural element comprising: wherein the first bar is positionable substantially circumferentially adjacent to the second bar when the stent is in the unexpanded state, the first bar being separable from the second bar upon angular rotation of the first bar with respect to the second bar at the coupling thereby expanding the stent to the expanded state, the one-way translational withdrawal of the articulating member from the aperture maintaining angular displacement between the first and second bars at the coupling in order to prevent collapse of the stent to the collapsed state upon being expanded to the expanded state.
