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: Disclosed herein are embodiments of a balloon shaped to have one or more enlarged regions to selectively increase expansion forces on an implant. For example, the balloon may have a central portion that is enlarged to exert more force on the center of a stent-mounted prosthetic heart valve. This overcomes the stent-mounted prosthetic heart valve's tendency to expand with flared ends. This forms a more cylindrical or barrel shaped stent frame during expansion of the balloon—reducing or eliminating the instance wherein the cylindrical stent frame has flared ends. Alternatively, the balloon may have conical flares placed to cause or enhance flared ends of the cylindrical implant to enhance its anchoring capabilities.

Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.

Abstract: A device for crimping a radially expandable and collapsible prosthetic valve comprises a coiled wire frame having a longitudinal opening extending from a proximal end to a distal end thereof. The opening has a first state and a second state, the opening in the first state having a first diameter dimensioned to receive the prosthetic valve in an expanded or partially crimped configuration therein, and the opening in the second state having a second diameter dimensioned to receive the prosthetic valve in a crimped configuration. The coiled wire frame has a first end coupled to a first member and a second end coupled to a second member. The first member is movable relative to the second member to convert the coiled wire frame from the first state to the second state.

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.
