Abstract: The present invention relates to a family of medical device packages designed and fabricated to provide instantaneous recognition as to the source and origin of a sterilized medical device stored therein and for passively retaining said medical device and related items in a desired manually accessible location within the package. The invention provides apparatus and methods for safely transporting, storing, identifying source and origin of, opening, packing and unpacking, evenly balanced packages containing sterilized implantable medical devices (IMDs). The packages and methods of the invention also are designed with features and structures that efficiently enhance the mechanical stability of one or more of the packages when stored in inventory at a clinic, in transport, and on an initial packaging site, and promote ease of handling and complement implant procedure efficiency in the operating room.
