Abstract: A heart valve delivery system is provided wherein a prosthetic valve is carried on a valve catheter inside a delivery sleeve. A step balloon protrudes from the delivery sleeve and provides a tapered surface for facilitating advancement through a body vessel. The step balloon also aids in crossing the leaflets of a native valve. After the prosthetic valve is positioned within the native valve, the delivery sleeve is retracted to expose the prosthetic valve. If necessary, the step balloon may be expanded to securely seat the prosthetic valve at the site of the native valve. The prosthetic valve is preferably coupled to the valve catheter by a plurality of flexible extension arms which allow the prosthetic valve to be collapsed after initial deployment such that the prosthetic valve may be repositioned if necessary.

Abstract: A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.

Abstract: Delivery apparatus and methods for delivering a medical device into a patient's vasculature are disclosed. In some examples, a method includes inserting, into a patient, a distal end portion of a delivery apparatus including a radially compressed prosthetic valve mounted around a balloon, advancing the distal end through the patient's vasculature, and inflating the balloon to radially expand the prosthetic valve at a native heart valve. The delivery apparatus includes a handle, a first shaft and a second shaft extending from the handle, and a locking mechanism to prevent axial movement of the second shaft relative to first shaft. The second shaft extends coaxially through the first shaft and includes the balloon, the radially compressed prosthetic valve, and one or more radiopaque markers at a distal end portion. The first shaft includes an end piece covering a proximal portion of the balloon during the advancing of the delivery apparatus.

Abstract: A delivery apparatus for a prosthetic heart valve includes a shaft, an inner balloon, and an outer balloon. The shaft has a lumen extending from a proximal end portion to a distal end portion and a plurality of openings formed in the distal end portion. The shaft is configured such that a fluid can flow through the lumen and the openings. The inner balloon has end portions and a center portion disposed between the end portions. The inner balloon is mounted on the distal end portion of the shaft and is in fluid communication with the openings of the shaft. When the inner balloon is inflated with the fluid, the end portions expand farther radially outwardly than the center portion. The outer balloon is mounted to the shaft and disposed over the inner balloon. The outer balloon is configured to fully expand after the inner balloon at least partially expands.

Abstract: A method for replacing a stenotic native aortic valve of a patient can include inserting a delivery apparatus into a femoral artery of the patient, the delivery apparatus having a first shaft extending from the handle, a second shaft disposed around the first shaft, a third shaft extending through the second shaft, and a valve cover coupled to the first shaft. The valve cover can be in a first state housing an entirety of a prosthetic heart valve and retaining the prosthetic heart valve in a radially compressed state during the act of inserting. The method can further include advancing the delivery apparatus through the aorta of the patient to position the valve cover and the prosthetic heart valve within the native aortic valve, and moving the valve cover longitudinally from the first state to a second state in which the entirety of the prosthetic heart valve is uncovered.

Abstract: An assembly for treating a native heart valve can include a prosthetic valve and a delivery apparatus. The prosthetic valve can include an expandable frame, a valve structure, a first end with apertures formed therein, and a second end. The delivery apparatus can include a valve catheter, flexible extension arms, slidable wires, and release members. First ends of the arms can be coupled to a cylindrical coupling element, second ends of the arms can be releasably coupled to the prosthetic valve, and the coupling element can be connected to the distal end of the valve catheter. The slidable wires can extend distally from the distal end of the valve catheter. The release members can be coupled to the distal end of the valve catheter and can extend through a respective aperture of the prosthetic valve, thereby forming a releasable connection between the prosthetic valve and the slidable wires.

Abstract: Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature without the need for a separate introducer sheath. The delivery apparatus is particularly well-suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a stenotic aortic valve.
