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.

Intravascular introducer devices

A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart includes a handle portion and an elongated shaft extending from and movable relative to the handle portion. The shaft includes a proximal end portion coupled to the handle portion and a distal end portion configured to mount a prosthetic heart valve in a radially compressed state. The handle portion includes a control member movable longitudinally with respect to the handle portion, the control member engaging a gear assembly operable to convert longitudinal motion of the control member to rotational motion of the gear assembly. The gear assembly engages the elongated shaft such that rotational motion of the gear assembly causes corresponding longitudinal motion of the elongated shaft relative to the handle portion.
