ABSTRACT:
A stent includes regions of differing numbers of braided filaments to provide different dimensions and/or properties in different regions along the stent length. The stent may include a first and second plurality of braided filaments each braided together. The second plurality of braided filaments is braided into the first plurality of braided filaments to form a region of different properties than the first. A method of constructing a braided stent includes the steps of braiding a first plurality of filaments to form the flexible portion, combining a second plurality of filaments to the first plurality of filaments, and then braiding the second plurality of filaments with the first plurality of filaments to form the more rigid region from the combination of the first and second plurality of filaments, where the second plurality of filaments is braided only in the rigid region.
