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: An apparatus and method 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: 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: Components for valve treatment systems are disclosed. Valve treatment systems can include a delivery system for an implantable device. The delivery system can include one or more of clasp control components slidably disposed on a catheter handle, a control element for opening and closing the implantable device, a catheter assembly with features to reduce friction with another catheter assembly, grips for attaching catheter assemblies to clamps, catheter assemblies with features that stiffen or provide variable stiffness, and catheter assemblies with one or more steering control lumens incorporated into a reinforcement layer.

Abstract: Embodiments of the present disclosure provide an introducer device and methods for introducing a medical device into a patient's vasculature. In one embodiment, a method of using an introducer device including a housing, a hemostatic seal mounted within the housing, and a tube extending into the housing and movable longitudinally relative to the hemostatic seal between a proximal position and a distal position, includes moving the tube to the distal position such that the distal end of the tube extends through the hemostatic seal. The method further includes inserting a distal end portion of the medical device through the tube and into the patient's vasculature without contacting the hemostatic seal.

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: A method for deploying an expandable prosthetic heart valve in a patient includes introducing a guidewire into a patient and advancing the guidewire through a vasculature of a patient to a deployment site. A distal end portion of a delivery apparatus and the prosthetic heart valve mounted in a radially compressed configuration along the distal end portion are advanced over the guidewire. The prosthetic heart valve is positioned at the deployment site. A screw mechanism is rotated, which exerts an axially directed onto the prosthetic heart valve, causing the prosthetic heart valve to radially expand from the radially compressed configuration to a radially expanded configuration.

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.
