Abstract

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 The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device.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.
