    Abstract: A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.

    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.

    IPC: A61F2/24

    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.
