Abstract:
1. A flexible device having a longitudinal axis, comprising: a first elongate member configured to move the flexible device in a first direction relative to the longitudinal axis; a second elongate member configured to move the flexible device in a second direction relative to the longitudinal axis that is different to the first direction; an articulation section including articulation links, wherein at least one of the articulation links includes a body configured to receive the first elongate member and the second elongate member; a first cinching element positioned to engage a first side of the first elongate member to restrict movement between articulation links when a first tensile force is applied to the first elongate member, and configured to disengage the first elongate member to permit movement between articulation links when a second tensile force is applied to the second elongate member; and a second cinching element positioned to engage a second side of the first elongate member to restrict movement between articulation links when the first tensile force is applied to the first elongate member, wherein the second side of the first elongate member is opposite the first side of the first elongate member.
