    摘要： An expandable helical stent is provided, wherein the stent may be formed of a main stent component and a securement. The main stent component is formed from a flat strip having one or more undulating side bands (401, 402) that may be connected to form geometrically shaped cells (430) and are helically wound to form a stent. 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 windings contributes to maintaining the tubular shape and uniformity of the helically coiled stent. Alternatively, the flat strip may comprise a single undulating pattern. At the ends of the main stent component are end bands (407), which when wound, form a cylindrical ring. In one embodiment, one or more struts of the main stent component may have a width sufficient to include one or more fenestrations. The fenestrated struts may be connected by loops or turns wherein the material is narrower than that of the fenestrated struts to provide enhanced flexibility. The helical tubular is maintained with a securement.

    摘要： The present invention relates to a stent (1') for use in a tubular organ of a body. The stent (1') comprises a first part (8) to be positioned in a diseased part (2) of the organ and acting as a stentbody therein, and a second part (10, 10', 40) to be positioned in a non-diseased part (6) of the organ and acting as an anchoring element therein. The two parts (8; 10, 10', 40) are being designed as tubular members interconnected at the ends facing one another by a flexible, axially rigid connecting part (9), at least said second part (10, 10', 40) having memorized therein a capacity to expand radially after an increase in temperature, thereby providing anchorage of the second part (10, 10', 40) at a determined distance away from the diseased part (2) of the organ.
