Abstract
A stent comprises a plurality of serpentine circumferential bands, and a plurality of connector columns. Each connector column is located between two adjacent circumferential bands and comprises one or more connector struts. Each connector strut is connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band. The number of connectors per connector column decreases from the first free end of the stent to the second free end of the stent.
Claims17
A stent having a first free end and second free end, the stent comprising
- a plurality of serpentine circumferential bands, and
- a plurality of connector columns, each connector column located between two adjacent circumferential bands, each connector column comprising at least one connector strut, each connector strut connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band,
- the number of connector struts per connector column decreasing uniformly from the first free end of the stent to the second free end of the stent.
A stent having a first free end and a second free end, the stent comprising
- a plurality of serpentine bands, and
- a plurality of connector columns, a connector column located between each two adjacent serpentine bands, each connector column comprising at least one connector strut, each connector strut connected at one end to one serpentine band and at another end to another serpentine band,
- wherein as the stent is traversed from the first free end to the second free end, each subsequent connector column includes less connector struts than any previous connector column.
A stent having a proximal end and a distal end, the stent comprising
- a plurality of serpentine bands, and
- a plurality of connector columns including a proximal most connector column and a distal most connector column, a connector column located between each two adjacent serpentine bands, each connector column comprising at least one connector strut, each connector strut connected at one end to one serpentine band and at another end to another serpentine band,
- wherein a selected connector column includes more connector struts than other connector columns located distally to the selected connector column, and the selected connector column includes less connector struts than other connector columns located proximally to the selected connector column.
