Abstract:
An expandable helical stent with a securement is provided. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristi. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other. The nestling of the undulation of adjacent helical coils contributes to maintaining the tubular shape of the helically coiled stent. In addition, the nestling of helical coils may prevent the polymer layer from sagging at any point between cycles of the helical coils.
