Slide-and-lock stent

A slide-and-lock stent, comprising a tubular member having longitudinal, radial, and circumferential axes, the tubular member comprising:

• a first longitudinal module and a second longitudinal module, the first longitudinal module and the second longitudinal module each comprising:
• a first end, a second end longitudinally opposite the first end, and an intermediate portion joining the first end and the second end, the first end comprising a closed loop;
• a spine extending along the intermediate portion, the spine comprising alternating peaks and valleys;
• a protrusion extending from at least one of the peaks of the first longitudinal module, the protrusion comprising a lockout tooth;
• and
• a slot extending through a region of at least one of the valleys of the second longitudinal module;
• wherein the protrusion of the first longitudinal module is configured to slidably engage with the slot of the second longitudinal module thereby circumferentially engaging the first longitudinal module and the second longitudinal module,
• wherein the lockout tooth is configured to allow one-way slidable movement of the first longitudinal module relative to the second longitudinal module during expansion of the tubular member from a radially unexpanded state to a radially expanded state.

A slide-and-lock stent, comprising a tubular member having longitudinal, radial, and circumferential axes, the tubular member comprising:

• a plurality of longitudinal modules, each of the longitudinal modules being identical in shape and comprising:
• a first end, a second end longitudinally opposite the first end, and an intermediate portion joining the first end and the second end;
• a spine extending along the intermediate portion, the spine comprising alternating peaks and valleys;
• a protrusion extending from at least one of the peaks, the protrusion comprising a lockout tooth;
• and
• a slot extending through a region of at least one of the valleys;
• wherein the protrusion of a first of the plurality of longitudinal modules is configured to slidably engage with the slot of a second of the plurality of longitudinal modules thereby circumferentially engaging the first of the plurality of longitudinal modules and the second of the plurality of longitudinal modules,
• wherein the lockout tooth is configured to allow one-way slidable movement of the first of the plurality of longitudinal modules relative to the second of the plurality of longitudinal modules during expansion of the tubular member from a radially unexpanded state to a radially expanded state.

A slide-and-lock stent, comprising a tubular member having longitudinal, radial, and circumferential axes, the tubular member configured to expand from a radially collapsed state to a radially expanded state, tubular member comprising:

• a plurality of longitudinal modules, each of the longitudinal modules comprising:
• a spine comprising a plurality of peaks, a plurality of valleys, and a plurality of struts, the peaks and valley alternating along the longitudinal axis, each of the peaks connected to at least one of the valleys by at least one of the struts, each of the struts extending substantially circumferentially and having a first circumferential length;
• a protrusion extending substantially circumferentially from at least one of the peaks, the protrusion comprising a lockout tooth, the protrusion having a second circumferential length, the second circumferential length being less than the first circumferential length;
• and
• a slot extending through a region of at least one of the valleys;
• wherein the protrusion of a first of the plurality of longitudinal modules is configured to slidably engage with the slot of a second of the plurality of longitudinal modules thereby circumferentially engaging the first of the plurality of longitudinal modules and the second of the plurality of longitudinal modules,
• wherein the lockout tooth is configured to allow one-way slidable movement of the first of the plurality of longitudinal modules relative to the second of the plurality of longitudinal modules during expansion of the tubular member from the radially collapsed state to the radially expanded state.
