    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: 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.
