  • Publication number: 20070074990
    Abstract: A sterile container assembly for storing sterile allograft tissue implant material is constructed to hold allograft bone tissue material mounted in a sterile blister package allowing drainage of the lipids contained in the implant without destroying the seal and sterility of the package. The package for storing sterile allograft tissue implant forms is constructed with an outer blister tray defining an open faced cavity and a flange extending outward from the tray cavity surrounding the cavity and an inner blister tray seated in the outer blister tray cavity. The inner blister tray also defines an open faced cavity and a flange extending outward from the cavity and a two piece implant insert having a recess allowing lyophilization while preventing lipid flow is mounted in the inner blister tray cavity. Lids are provided for both the inner and outer blister trays.

  • Patent number: 4959068
    Abstract: A sterile surgical needle having a dark, non-reflective and non-flaking surface. The needle is produced by selecting an appropriately shaped needle having the desired degree of sharpness. The needle is treated to activate the surface and then immersed in a solution of sulfuric acid, potassium dichromate and water to form a dark, non-reflective, non-flaking surface. The needle is sterilized to produce a sterile surgical needle of improved visibility.
