Abstract: Assemblies and delivery apparatus for delivering a medical device into a patient's vasculature are disclosed. In some examples, an assembly includes a delivery apparatus and a radially compressible and expandable prosthetic 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, at a distal end portion thereof, a balloon, one or more radiopaque markers, and the prosthetic valve radially compressed over the balloon. A flared end piece extending from the first shaft covers a proximal portion of the balloon during advancing of the delivery apparatus through a patient's vasculature. The first shaft is retractable relative to the second shaft to expose the balloon from the flared end piece.

Abstract: Embodiments of the present disclosure provide a delivery apparatus for a prosthetic heart valve. Disclosed delivery apparatuses can include a handle, a first shaft extending from the handle, a second shaft disposed around the first shaft, and a valve cover. The valve cover can be coupled to a distal end portion of the first shaft and can be configured to house a prosthetic heart valve in a radially compressed state. The valve cover can have an outer diameter greater than an outer diameter of the second shaft, and the first shaft and valve cover can be movable together in an axial direction relative to the second shaft.

Abstract: 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.

Abstract: Embodiments of the present disclosure provide a delivery apparatus for a prosthetic heart valve. Disclosed delivery apparatuses can include a housing, a steerable shaft, a slide nut, and a threaded shaft disposed over the slide nut. The slide nut can have an external threaded surface and an internal surface comprising a slot. The threaded shaft can have an internal threaded surface engaging the external threaded surface of the slide nut. The delivery apparatus can further include an elongated nut guide extending into the slot of the nut to restrain the slide nut against rotation relative to the housing, and a pull wire having a proximal end portion extending into the housing and coupled to the slide nut, and a distal end portion coupled to a distal end portion of the steerable shaft. The threaded shaft can be rotatable relative to the housing to produce axial movement of the slide nut within the threaded shaft.

Abstract: Embodiments of the present disclosure provide an introducer device for introducing a medical device into a patient's vasculature. In one embodiment, the introducer device comprises a housing, a distal sheath adapted to be inserted into a patient's vasculature with the housing positioned outside of the patient's vasculature, a hemostatic seal mounted within the housing, and a tube positioned within the housing and movable longitudinally relative to the hemostatic seal between a proximal position and a distal position. In the proximal position, a distal end of the tube is positioned proximal to the hemostatic seal with the hemostatic seal closed. In the distal position, the distal end of the tube extends through the hemostatic seal and permits the medical device to be inserted through the housing and into the patient's vasculature without contacting the hemostatic seal.

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.

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: 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.
