1. A device for removing a clot from a blood vessel, comprising:
a flexible activation cable comprising:
a shaft; and
an expandable framework of struts located distal of the shaft, the expandable framework of struts being radially expandable from a first radially expanded state to a second radially expanded state in a deployed configuration, the expandable framework of struts fixedly coupled to a stop located in a distal region of the flexible activation cable and within the expandable framework of struts,
wherein the flexible activation cable applies an expansion force, by the stop, such that the expandable framework of struts is actuated by the flexible activation cable and the stop from the first radially expanded state to the second radially expanded state;
wherein in the first radially expanded state, a distal end of the expandable framework of struts is spaced a first axial distance away from the shaft, and wherein in the second radially expanded state, the distal end of the expandable framework of struts is spaced a second axial distance, different than the first axial distance, away from the shaft.
