  • Apparatus and method for delivery of a prosthetic valve device
    Patent number: 11357628
    Abstract: A catheter and a method for using the catheter to implant a replacement aortic valve into a patient. The catheter includes an expandable wall, an outer sheath, a first tube operably coupled to the expandable wall, and a second tube operably coupled to the expandable wall. The catheter also includes a pusher that is fixed to the second tube, the pusher being spaced apart from the expandable wall by a distance that is sufficient to accommodate the replacement aortic valve. The outer sheath is movable relative to the expandable wall so that in one state the expandable wall is disposed within the outer sheath and in another state the expandable wall is located outside of the outer sheath. The expandable wall is configured to radially expand. The catheter also includes a handle assembly that is adjusted by a surgeon to achieve the functions of the catheter.
