摘要： A system and method used to deliver a valve delivery system carrying a valve to a target valve annulus in the heart includes a cable percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, transseptally through the heart, to a femoral artery. The valve delivery system device is passed over an end of the cable at the arterial side and is secured to the cable. The valve delivery system device is pushed in a distal direction while the venous end of the cable is pulled in the proximal direction, to advance the valve delivery system to the target valve annulus. A left ventricle redirector positionable on the cable from the venous end has a distal end actively steered during advancement and positioning of the valve delivery device, exerting forces that steer the distal nose of the valve delivery device as it moves towards the valve annulus.

摘要： A system and method for extracting a pVAD device that is implanted with a distal portion in an aorta of the heart and a drive line extending across an inter-atrial septum and out of the body via a superior vessel of the venous vasculature, include a first device that is introduced into a femoral artery and through the descending aorta used to engage a distal part of the pVAD device in the aorta of a patient using an instrument. A second, cutter, device is introduced into the venous vasculature superior to heart, advanced to a position adjacent the inter-atrial septum, and used to cut the pVAD drive line adjacent to the inter-atrial septum. After cutting, a first portion of the pVAD is withdrawn from the body via the venous vasculature, and a second portion is withdrawn from the body via the femoral artery.

摘要： A system and method used to deliver an aortic valve therapeutic device to an aortic valve site includes a cable percutaneously introduced a cable 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 therapeutic device is passed over an end of the cable at the venous side and is secured to the cable. The therapeutic device is pushed in a distal direction while the second end of the cable is pulled in the proximal direction to advance the therapeutic device to the mitral valve site. A left ventricle redirector aids in orienting the therapeutic device and preventing migration of the cable towards delicate mitral valve structures and chordae tendoneae during advancement of the therapeutic device.

摘要： Disclosed are a system and method for performing a medical procedure using direct percutaneous access of an aorta. A main sheath is introduced through an incision formed in proximity to the sternum, and positioned along (and preferable against) a posterior portion of the sternum. Instruments passed through the main sheath are used to form a purse-string suture in an exterior wall of the aorta. An opening is formed in the wall of the aorta in a region encircled by the purse-string suture, and a distal end of an introducer sheath is advanced through the opening into the aorta. A medical procedure, which may be a transcatheter aortic valve replacement, is performed using instruments passed through the introducer sheath into the aorta. After the medical procedure, the introducer sheath is withdrawn from the aorta and, as the introducer sheath is withdrawn, the purse-string suture is tightened to close the opening.

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.
