A multi-section filamentary stent comprises a braided section of a first set of filaments, connected to at least one wound section comprising a second set of one or more filaments having a repeating configuration with a bent portion. The stent may comprise a first section, having a braided first stent architecture with a first flexibility and a first radial force, and a second section, having a non-braided second stent architecture with a secoid flexibility less than the first flexibility and a second radial force greater than the first radial force, in which at least one continuous filament is integral to both the first and second sections. The stent may have a radially compressed configuration and a radially expanded configuraton, in which the first section has a first shortening ratio, and the second section has a second shortening ratio less than the first shortening ratio. |
