Title: HUMIDITY-MANAGEMENT PACKAGING SYSTEMS AND METHODS
Abstract:
Packaging systems and methods are disclosed for storing a bioprosthetic device comprising a bioprosthetic tissue and maintaining a target relative humidity across a temperature range. The packaging system includes a sealed package defining an internal space having an internal volume, and a humidity control device and bioprosthetic device within the internal space. The humidity control device includes a barrier defining an enclosed space and a humidity control solution comprising glycerol in the enclosed space. At least a portion of the barrier comprises a gas-permeable membrane. The target relative humidity is provided within the internal volume of the sealed package and the control device maintains the target relative humidity across the temperature range by selectively liberating and absorbing water vapor.
