Abstract: A press-on retainer is configured to retain a fire-stop sleeve in an opening. The retainer includes a body formed of sheet metal. The body is configured to define a concave shape, a hole in the body, and a plurality of segments extending radially from the hole. Each segment is includes an angled portion at the end of the segment that defines the hole with a diameter suitable to accept the sleeve. The angled portions are configured to allow the retainer to be pressed onto the sleeve in a first direction, and thereafter prevent the retainer from being moved in a second direction opposite the first direction.

Abstract: A package for sterilized, absorbable medical devices is disclosed. The package has a plurality of cavities in communication with a vent, wherein the vent is preferably centrally located. After sterilization, the package is sealed adjacent to the vent thereby providing individual hermetically sealed sterile cavities which are cut away from the package to form unitary packages.
