Abstract
A package for a prosthetic heart valve or the like comprising a pair of separable mating package sections for receiving the heart valve and retaining it in sterile manner in biased position against a resilient pad. A separate retainer member is positioned in the package for biasing the heart valve against the pad, the retainer member being a rigid sheet having an aperture adapted to receive a portion of the valve. One of the mating package sections is provided with a shoulder which urges the retainer member into a biased position against the heart valve so that the valve is in turn biased against the resilient pad. The shoulder is adapted to slide along the surface of the retainer member so that the torque is not transmitted to the heart valve when the package sections are rotated to open or close the package.
Claims6
In a package for prosthetic heart valve and the like comprising a pair of separable, mating package sections for receiving said heart valve, and retaining said valve in sterile manner in biased position against a resilient pad carried by one of said package sections, the improvement comprising:
- (a) a separate retainer member positioned within said package for biasing said heart valve against the resilient pad, said retainer being a rigid sheet having an aperture shaped to receive a portion of said valve, and
- (b) a shoulder defined in one of said mating package sections, said shoulder being adapted to urge the retainer member into a biased position against the heart valve so that the heart valve is in turn biased against the resilient pad, said shoulder being further adapted to slide easily along the surface of the retainer member so that torque is not transmitted to the heart valve when the mating package sections are rotated to open or close the package.
In a package containing a prosthetic heart valve which includes a pair of separable, mating package sections for receiving such heart valve, and a resilient pad positioned in one of said package sections, the improvement which is a separate retainer member adapted to urge said heart valve against said resilient pad, said retainer member being positioned within the package when the two package sections are mated so that it is spaced from the package section containing the pad and in contact with although not connected to the other package section, said retainer member being adapted not to rotate with either of the package sections so that torque is not transmitted to the heart valve when the mating package sections are rotated relative to each other for opening and closing the package.
