Abstract

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; and a deflection control member coupled with the 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, and wherein the deflection control member is configured to move freely when the selective movement limiter is not coupled with the deflection control member.
