Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a sterile jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. A delivery handle on the end of a shaft couples with the valve holder while the packaging sleeve engages the jar to prevent rotation. The assembly of the packaging sleeve, valve, and holder can then easily be removed from the jar.

1. A packaged prosthetic heart valve assembly, comprising: a jar having an open end and a closed bottom, and a plurality of inwardly-directed rails circumferentially distributed around the jar interior;a prosthetic heart valve having an inflow end and an outflow end;a valve holder attached to one end of the valve; anda generally tubular packaging sleeve having a tubular wall sized to fit closely within the jar and having structure to which the valve holder removably couples so that the heart valve is restrained from gross movement within the jar, the sleeve further including a plurality of radially-outwardly projecting protrusions in the tubular wall circumferentially distributed around a sleeve periphery, there being at least two differently configured and axially-spaced protrusions at each circumferential location, wherein an exterior diameter defined by the protrusions is larger than an inner diameter defined by the rails so as to create an anti-rotation interference between the sleeve and the jar to limit rotation of the sleeve while in the jar, the sleeve further including vents in the tubular wall between each circumferential location at which there are protrusions. 2. The assembly of claim 1, wherein the plurality of protrusions are evenly circumferentially distributed around the sleeve periphery, and there are two inwardly-directed rails on the jar for every circumferential location at which there are protrusions on the sleeve so that each protrusion may be flanked by a pair of rails, the sleeve thus having a limited freedom of rotation in the jar equal to the angular spacing of each pair of rails. 3. The assembly of claim 1, wherein there are the same number of circumferential locations at which there are protrusions as the inwardly-directed rails on the jar. 4. The assembly of claim 1, wherein the protrusions at each circumferential location at which there are protrusions comprise a linear rib and a bump that is axially shorter than the linear rib. 5. A packaged prosthetic heart valve assembly, comprising: a cylindrical jar having an open end and a closed bottom, and a cylindrical inner wall;a prosthetic heart valve having an inflow end and an outflow end;a valve holder attached to one end of the valve and including mating structure for attachment of a delivery tool; anda generally tubular packaging sleeve having a tubular wall sized to fit closely within the jar and having a clip to which the valve holder removably couples, the sleeve further including at least two pairs of protrusions in the tubular wall circumferentially distributed around a sleeve periphery in opposing relationship, wherein the two protrusions in each pair are differently configured, an exterior diameter defined by the protrusions being larger than an inner diameter of the inner wall of the jar so as to create an anti-rotation interference between the sleeve and the jar and facilitate attachment of the delivery tool to the valve holder. 6. The assembly of claim 5, wherein the valve holder includes an internally threaded bore for attachment of a threaded male portion of the delivery tool. 7. The assembly of claim 5, wherein the plurality of protrusions are both circumferentially and axially distributed around the sleeve periphery so as to help center and align the sleeve and jar axes. 8. A packaged prosthetic heart valve assembly, comprising: a jar having an open end and a closed bottom, and a plurality of inwardly-directed rails circumferentially distributed around the jar interior;a prosthetic heart valve having an inflow end and an outflow end;a valve holder attached to one end of the valve; anda generally tubular packaging sleeve having a tubular wall sized to fit closely within the jar and having structure to which the valve holder removably couples so that the heart valve is restrained from gross movement within the jar, the tubular sleeve defining a lower rim and further including a plurality of feet extending downward from the rim which contact the bottom of the jar when positioned therein so as to raise the lower rim above the bottom and permit fluid flow therebetween, the sleeve further including a plurality of vertically-oriented anti-rotation ribs in the tubular wall circumferentially distributed around and extending outward from a sleeve periphery and located above the lower rim, there being at least two differently configured and axially spaced ribs at multiple circumferential locations, wherein an exterior diameter defined by the ribs is larger than an inner diameter defined by the rails so as to create an anti-rotation interference between the sleeve and the jar to limit rotation of the sleeve while in the jar, and wherein there are two inwardly-directed rails on the jar for every rib on the sleeve so that each rib may be flanked by a pair of rails, the sleeve thus having a limited freedom of rotation in the jar equal to the angular spacing of each pair of rails, the sleeve further including vents in the tubular wall between each circumferential location at which there are protrusions. 9. The packaging sleeve of claim 8, further including a plurality of anti-rotation bumps extending outward from the sleeve periphery, one bump for each rib and each bump is axially aligned with an associated rib. 10. The packaging sleeve of claim 8, wherein each pair of two inwardly-directed rails on the jar is circumferentially spaced apart by between about 15-30°. 11. The packaging sleeve of claim 8, further including a plurality of vertical struts circumferentially distributed around the tubular packaging sleeve and projecting upward. 12. The packaging sleeve of claim 8, wherein the valve holder snaps onto a flat disk that extends outward and is supported by the tubular packaging sleeve, and wherein the valve holder includes three legs that couple to a sewing ring on the prosthetic heart valve via sutures, the valve holder further including a female threaded bore on the top end of a holder post that is rotatable relative to the legs and a central hub structure, and the post has an axial key that prevents downward movement of the post until it aligns with a keyway in the central hub structure, and wherein rotation of a delivery handle after bottoming out into the female threaded bore of the post thus rotates the post such that the key aligns with the keyway to permit the post to move axially.
