Claim 17:
18. A method of storing at least one bioprosthetic device within a packaging system, the method comprising the steps of:
selecting a target relative humidity to be substantially maintained within an internal volume of an outer packaging across a temperature range when the outer packaging is sealed;
providing at least one humidity control device comprising a humidity control solution within an at least partially gas-permeable enclosure, wherein the humidity control solution has a total weight, wherein a ratio of the total weight of the humidity control solution to the internal volume of the outer packaging when the outer packaging is sealed is at least about 6 mg/mL, wherein the humidity control solution is configured to maintain a relative humidity within the internal volume of the outer packaging within about ±5% of a target relative humidity across a temperature range from about −18° C. to about 45° C., by selectively liberating and absorbing water vapor through the at least partially gas-permeable enclosure, and wherein the target relative humidity is selected from the range from about 15% to about 95%;
placing the at least one humidity control device and the at least one bioprosthetic device within the internal volume of the outer packaging; and
sealing the outer packaging containing the at least one humidity control device and the at least one bioprosthetic device.
