摘要： 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.

摘要： A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD.
