1. An elongate medical device, comprising:
an expandable structure with an expandable configuration and a collapsed configuration;
a handle, operably coupled to the expandable structure, the handle further including a selective movement limiter that is housed inside of the handle; and
a deflection control member coupled with a distal hub, where the deflection control member is configured to adjust a stiffness of the expandable structure, from a first stiffness to a second stiffness, and maintain the first stiffness or the second stiffness when the selective movement limiter couples with the deflection control member and limits a longitudinal movement of the deflection control member;
wherein the deflection control member is configured to move freely when the selective movement limiter is not coupled with the deflection control member.
