Slide-and-lock stent

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

• a first radial element comprising an actuating rail having an actuator disposed thereron;
• a second radial element, circumferentially adjacent to the first radial element, and slidably engaged with the first radial element, the second radial element comprising a deflectable catch element;
• and
• a lockout catch,
• wherein the actuator is configured so that as the second radial element slides relative to the first radial element, the actuator deflects the deflectable catch element thereby engaging the lockout catch, such that said tubular member achieves expansion in the circumferential axis with reduced recoil.

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

• a first radial element comprising a deflectable rail having a lockout tooth disposed thereron;
• and
• a second radial element, circumferentially adjacent to said first radial element, and slidably engaged with said first radial element, the second radial element comprising a slot,
• wherein the slot is configured to slidably engage and deflect said deflectable rail as the lockout tooth disposed on the deflectable rail passes through the slot, such that said tubular member achieves expansion in the circumferential axis with reduced recoil.

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

• a first radial element comprising a first serrated surface;
• and
• a second radial element, circumferentially adjacent to and slidably engaged with said first radial element, and comprising a second serrated surface,
• wherein the first and second serrated surfaces engage one another in a complimentary hill and valley configuration adapted to resist sliding, whereby once expanded by application of radial force, said tubular member resists recoil.

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

• a first module comprising at least two circumferentially offset slide-and-lock radial elements and a coupling element, wherein each radial element comprises a tab, a gap comprising lockout teeth, and a slot;
• and
• a second module configured substantially identical to said first module and circumferentially adjacent to said first module,
• wherein the radial elements from said second module are slidably engaged within the slots of the corresponding radial elements from said first module, and wherein the tabs of the radial elements from said second module are slidably engaged within the gaps of the corresponding radial elements from said first module, such that the lockout teeth engage the tabs to minimize recoil.
