Devices, systems, and methods for treating blood flow channels are disclosed herein. For example, an expandable instrument of the present technology may include a stent having a contracted configuration and an expanded configuration for delivery by a delivery instrument to a treatment site in a body conduit. The stent may include a plurality of struts and longitudinally extending first and second ridges configured to move in opposite axial directions as the stent expands. Each strut may extend between and connect one of the first ridges and one of the second ridges. Axial movement of the first ridge relative to the second ridge may cause the struts to urge circumferentially adjacent ridges to move away from each other, thereby increasing the diameter of the stent. 本文公开了用于治疗血流通道的器械、系统和方法。例如，本技术的可膨胀器械可以包括具有用于通过输送器械输送至身体管道中的治疗部位的收缩构型和膨胀构型的支架。该支架可包括多个支柱和纵向延伸的第一脊部和第二脊部，这些脊部被配置为随着支架膨胀而沿相反的轴向方向移动。每个支柱可以在一个第一脊部和一个第二脊部之间延伸并连接所述一个第一脊部和所述一个第二脊部。相对于第二脊部轴向移动第一脊部可能导致支柱推动周向相邻的脊部以远离彼此移动，从而增大支架的直径。
