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 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 a prosthetic heart valve. Disclosed steerable catheters can include a handle, a steerable shaft extending from the handle, and a pull wire. The shaft can include a main lumen, an inner polymeric layer surrounding the main lumen, a braided layer surrounding the inner polymeric layer, and an outer polymeric layer surrounding the braided layer, the outer polymeric layer defining a pull wire lumen. The pull wire can extend from the handle and through the pull wire lumen and can have a distal end portion coupled to a distal end portion of the shaft.

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 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.
