Abstract:
1. An expandable slide and lock stent, the stent comprising a tubular member having a circumference and a longitudinal axis, the stent comprising: a first backbone and a second backbone, the first and the second backbones each having a reversing helical shape, a first part of the shape extending in a clockwise circumferential direction and reversing into a second part of the shape, the second part extending in a counterclockwise circumferential direction, the first and second backbones extending along at least a portion of the circumference and along the longitudinal axis; a rail member defining proximal and distal ends, the proximal end of the rail member being coupled to the first backbone, the distal end of the rail member extending from the first backbone in the circumferential direction, the rail member configured to engage with an engagement element in the second backbone; and wherein the rail member is configured to provide one-way movement of the second backbone away from the first backbone such that the tubular member can be expanded between a collapsed diameter and an expanded diameter.
