Abstract: A transcatheter delivery system including an expandable transition element is disclosed. As one example, an assembly may comprise a prosthetic valve and a delivery device. The delivery device may comprise an outer shaft with a distal end portion forming a sheath adapted to enclose the prosthetic valve therein in a radially compressed configuration; an inner shaft arranged within the outer shaft and including a nosecone arranged at a distal end of the inner shaft, the nosecone arranged outside of the outer shaft, at the distal end portion of the outer shaft; and an expandable transition element adapted to expand from a non-expanded state within the outer shaft to an expanded state outside the outer shaft, wherein, in the expanded state, the transition element forms a continuous transition from the nosecone to the prosthetic valve when the sheath is moved away from the nosecone to uncover the prosthetic valve.

Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.

Abstract: An assembly can comprise a radially expandable and compressible annular frame, at least one linear actuator assembly coupled to the frame and at least one locking mechanism coupled to the frame. The linear actuator can be configured to apply a distally directed force and/or a proximally directed force to the frame to radially expand or compress the frame. The locking mechanism can comprise a first sleeve member connected to the frame at a first location, a second sleeve member having internal threads and being connected to the frame at a second location, and a first screw configured to engage the internal threads of the second sleeve member to retain the frame in a radially expanded state.

Abstract: A prosthetic heart valve can include a frame, a valve component, a sealing member, and a retaining member. The frame can be radially compressible and expandable between a radially-compressed configuration and a radially-expanded configuration. The valve component can be disposed within and coupled to the frame and have a plurality of leaflets. The sealing member can have a plurality of ribs and a plurality of connectors. The ribs can be coupled to and extend radially outwardly from the frame when the frame is in the radially-expanded configuration. The connectors can be coupled to and extend radially between the frame and the ribs. The sealing member can be configured to reduce or prevent perivalvular leakage around the prosthetic heart valve. The retaining member can be coupled to the frame and the sealing member and can retain the sealing member at a desired spacing relative to the frame.

Abstract: Disclosed herein are reinforced expandable introducer sheaths and methods of using the same. The sheaths minimize trauma to the patient's vasculature by including a reinforcing member to improve the push force of the sheath while reducing the chances of kinking during delivery of a prosthetic device. The sheath can include a plurality of expandable rings aligned along the longitudinal axis of the sheath and coupled together to form an elongated tubular structure. The sheath can also include a plurality of radial members circumferentially arranged to form a tubular support structure. The radial members slidingly interconnected around the circumference of the tubular structure to facilitate radial expansion of the sheath.

Abstract: The expandable sheath and methods of use disclosed herein are used to deliver a prosthetic device through a patient's vasculature. The sheath is constructed to be expandable in the circumferential direction, while maintaining sufficient stiffness in the longitudinal direction to withstand pushing and resist kinking. The sheath includes a plurality of curved arms extending outwardly from a longitudinally extending spine. The curved arms move away from the longitudinal axis of the sheath when pushed radially outwardly by a passing prosthetic device, and move back toward the longitudinal axis once the prosthetic device has passed.
