Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature. 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.

A heart valve delivery apparatus includes a valve carrying member. A prosthetic valve is crimped onto the valve carrying member at a location that is distal or proximal to the balloon member, thereby providing a smaller profile delivery apparatus.

Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

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.

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.

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.

Embodiments of the present disclosure provide an introducer device and method for introducing a delivery apparatus into a patient's vasculature. Disclosed methods can include positioning a sleeve of an introducer sheath in a blood vessel of a patient, the sleeve having a lattice layer with a lumen therethrough, inserting a distal end portion of the delivery apparatus and a prosthetic heart valve into the lumen, and advancing the distal end portion of the delivery apparatus through the lumen from the proximal end to the distal end. The method can then include expanding the lumen from a first diameter smaller to a second diameter at least equal to the diameter of the prosthetic heart valve to allow passage of the prosthetic heart valve through the lumen, and returning the lumen of the sleeve to a diameter smaller than the second diameter after advancing the prosthetic heart valve through the lumen.

In one representative embodiment, a steerable catheter device comprises a shaft comprising a proximal portion and a distal portion, and first and second pull wires having respective proximal portions and respective distal portions. The proximal portions of the first and second pull wires extend through the proximal portion of the shaft in close proximity to each other. The distal portions of the first and second pull wires extend through the distal portion of the shaft in close proximity to each other over a first distance defining a primary flexing section, diverge away from each other over a second distance, and then extend parallel to each other at angularly spaced locations over a third distance defining a secondary flexing section.
