A tubular stent is disclosed that is made of a series of bands having a generally tubular shape with an open end. Each band has an open rectangular form made of an elongated material. The bands have the open ends (or interruptions) in an offset manner and each band has crosstie or ties which are either rigid or flexible. Ties, even if they are straight, can be disposed close to each other, or further away from each other, and can vary in number in order to adjust the relative stiffness of the stent. Each of the bands are preferably a generally rectangular shape and can be made from a wire of a variety of different cross-sections, or can be cut from a flat sheet, or burned out of a cylindrical shape. |
