Abstract
Devices, systems, and methods for treating a blood flow passage are disclosed herein. For example, expandable devices of the present technology may comprise a stent having a collapsed configuration for delivery through a delivery device to a treatment site in a body conduit and an expanded configuration. The stent may comprise a plurality of struts and longitudinally extending first and second spines configured to move in opposing axial directions as the stent expands. Each of the struts may extend between and connect one of the first spines and one of the second spines. Moving the first spines axially relative to the second spines may cause the struts to push circumferentially adjacent spines to move away from one another, thereby increasing a diameter of the stent.
