Abstract

An instrument for facilitating transseptal delivery of a cardiac therapeutic device is positionable in a left ventricle. The instrument includes an elongate shaft having a tubular lumen, the shaft having a proximal portion and a distal portion actively steerable between a generally straight position and a curved position. An external pull wire and an internal pull wire are each actuatable to move the distal portion to the curved position. The external pull wire extends internally through the proximal portion of the shaft and longitudinally along the exterior of the distal portion of the shaft, while the internal pull wire extends internally through the proximal portion of the shaft adjacent to the external pull wire, and extends internally through the distal portion of the shaft.
