Multi-section filamentary endoluminal stent

A multi-section filamentary stent comprising:

• a first section, having a first stent architecture comprising one or more filaments in a first geometric configuration, the first stent architecture having a first flexibility and a first radial force, and
• a second section, having a second stent architecture comprising one or more filaments in a second geometric configuration, the second stent architecture having a second flexibility less than the first flexibility and a second radial strength greater than the first radial strength;
• wherein the stent comprises at least one continuous filament contained in both the first and second sections and the first stent architecture comprises a braided stent architecture.

A multi-section stent having a radially compressed configuration and a radially expanded configuration, the stent comprising a first section having a first, braided stent architecture with a first shortening ratio, and a second section having a second, wound stent architecture with a second shortening ratio, the first shortening ratio being greater than the second shortening ratio, the stent comprising at least one continuous filament contained in both the first and second sections.

A modular stent comprising at least two modular components adapted to be joined together in situ:

• a first modular component comprising a multi-section stent comprising a first section, having a first stent architecture and a first geometric configuration with a first flexibility and a first radial force, and a second section, having a second stent architecture and a second geometric configuration with a second flexibility less than the first flexibility and a second radial force greater than the first radial force, the first component comprising at least one continuous filament contained in both the first and second sections;
• and
• a second modular component comprising a multi-section filamentary stent comprising a third section, having a third stent architecture and a third geometric configuration and a fourth section, having a fourth stent architecture in a fourth geometric configuration, the second component comprising at least one continuous filament contained in both the third and fourth sections.

A multi-section filamentary stent comprising:

• a first section, having a first stent architecture comprising one or more filaments in a first geometric configuration, the first stent architecture having a first percentage of open area, and
• a second section, having a second stent architecture comprising one or more filaments in a second geometric configuration, the second stent architecture having a second percentage of open area greater than the first percentage;
• wherein the stent comprises at least one continuous filament contained in both the first and second sections and the first stent architecture comprises a braided stent architecture.

A method of counteracting an end effect marked by a reduction in radial strength along an end length of a first stent section having a first stent architecture comprising one or more filaments in a first geometric configuration and having a first radial strength except for a second, lesser radial strength in said end length, the method comprising connecting a second stent section having a second stent architecture comprising one or more filaments in a second geometric configuration, the second stent architecture having a radial strength greater than the second radial strength.
