Patent number: 6503230Abstract: A syringe assembly includes a needle sheath that has a cavity that receives a needle cannula. The needle sheath can be formed of materials such as thermoplastic elastomers or plastics yet still be utilized with conventional gas sterilizing processes. The needle sheath includes a passage that permits the sterilizing gases to enter the cavity while preventing entry of microorganisms into the cavity. Thus, a syringe assembly is provided that facilitates sterilizing a needle after the needle sheath has been placed over the needle.Type: GrantFiled: August 1, 2001Date of Patent: January 7, 2003Inventors: Robert B.

Patent number: 6126640Abstract: A protective sealing barrier for a syringe is disclosed. The protective sealing barrier can be configured to safeguard the sterility of the syringe and any contents held therein, as a barrier against leakage of any contents held within the syringe, or both. The syringe includes a luer tip and a collar having terminal ends which are preferably substantially co-planar with one another. The barrier consists of a membrane which is disposed in substantially entire surface contact with the terminal ends of both the luer tip and the collar. The membrane can be selected from a material permitting the syringe to be irradiated or heat sterilized. Likewise, the membrane can be chosen from a material permitting the syringe to be sterilized by various gas sterilization procedures.Type: GrantFiled: July 10, 1998Date of Patent: October 3, 2000Assignee: Becton, Dickinson and CompanyInventors: Robyn Laurie Tucker, Sandor Gyure, Robert B.
