Abstract
Systems and methods for operating steerable sheath (SS). The methods comprise: causing an inner shaft (IS) to move in a first direction (FD) relative to an outer shaft (OS) having a first lumen (FL) in which IS is disposed; applying tension to a first pull wire (FPW) as IS moves in FD (FPW being partially disposed in a wall of IS and in FL of OS, FPW's first end being connected to IS and FPW's second end being connected to OS); allowing a deflectable region of IS's wall to transition from a straight state to a deflected state as tension is applied to FPW; causing IS to move in a second direction relative to OS; removing the tension being applied to FPW as IS moves in the second direction; and allowing the deflectable region of IS's wall to return to the straight state as tension is being removed from FPW.
