    Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

    Abstract: A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.

    Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.

    Abstract: A prosthetic heart valve holder system includes a prosthetic heart valve having a base at an inflow end, a plurality of commissure posts extending from the base toward an outflow end, and valve leaflets secured to the commissure posts to permit flow through the heart valve. A deflector is provided at the outflow end having a central hub and a plurality of arms extending from the central hub secured to and covering the tips of respective commissure posts. A valve support body is secured to the base and a post connects the valve support body to the hub of the deflector. The plurality of arms are sufficiently collapsible such that, in a first position, free ends of the arms are located axially between the hub and the valve support body to prevent suture looping during an implant procedure, and in a second position, the hub is located axially between the free ends of the arms and the valve support body to permit removal of the deflector from the outflow side of the valve, through the valve leaflets, to the inflow side of the valve.
