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 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: Disclosed embodiments of introducer devices provide hemostatic sealing and allow a delivery catheter to be inserted through the introducer seals without the use of a separate loader device that covers a medical device that is mounted on the catheter. Some disclosed introducers comprise a housing, a distal sheath extending distally from the housing and adapted to be inserted into a patient's vasculature, a distal hemostatic seal mounted within the housing and a proximal hemostatic seal mounted within the housing, and a slidable tube positioned within the housing that is movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal.

Abstract: An apparatus for delivering a prosthetic device through the vasculature of a patient includes a radially expandable member coupled to the distal end of an elongate shaft. The expandable member has an open frame configuration and an outer mounting surface for mounting the prosthetic device in a collapsed state thereon. The expandable member expands radially outwards from a first configuration to a second configuration to expand a prosthetic device mounted thereon.

Abstract: An assembly includes a prosthetic heart valve and a delivery apparatus for implanting the prosthetic heart valve within the native aortic valve of a patient. The prosthetic heart valve has a radially compressible and expandable metallic stent and a flexible valvular structure mounted within the stent. The delivery apparatus has a handle, a first shaft having a proximal end portion and a distal end portion, a second shaft extending co-axially through the first shaft and having a proximal end portion and a distal end portion, the proximal end portions of the first and second shafts extending distally from the handle, a valve cover coupled to the distal end portion of the first shaft, and a nose piece coupled to the distal end portion of the second shaft.

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.
