Abstract
A stent configured for implantation in a body lumen includes a plurality of radially expandable circumferential segments, and an axially expandable connecting member connecting adjacent circumferential segments of the plurality. The stent has a relaxed, axially contracted configuration in which the connecting member is contracted axially and each circumferential segment is nested with at least one adjacent circumferential segment. The stent also has a delivery, axially expanded configuration in which the connecting member is expanded axially, and an axial distance between adjacent circumferential segments of the plurality is greater than when the stent is in its relaxed configuration.
Claims15
A stent configured for implantation in a body lumen, comprising:
- a plurality of radially expandable circumferential segments;
- and
- an axially expandable connecting member connecting adjacent circumferential segments of the plurality,
- wherein the stent has
- an axially contracted configuration in which the connecting member is contracted axially, and each circumferential segment is nested with at least one adjacent circumferential segment, and
- an axially expanded configuration in which the connecting member is expanded axially, and an axial distance between adjacent circumferential segments of the plurality is greater than when the stent is in its axially contracted configuration.

- wherein the stent has
- a relaxed configuration in which the connecting member is contracted axially, and each circumferential segment is nested with at least one adjacent circumferential segment, and
- a delivery configuration in which the connecting member is expanded axially, and an axial distance between adjacent circumferential segments of the plurality is greater than when the stent is in its axially contracted configuration,
- wherein, when the stent is in its delivery configuration, the connecting member is biased to contract axially, and the circumferential segments are biased to expand radially, and
- wherein the plurality of circumferential segments and the connecting member are configured such that radial compression of the circumferential segments exerts an axially expanding force on the connecting member.
