  • Low silicone glass prefillable syringe
    Patent number: 7141042
    Abstract: A method for lubricating a sealing member in a drug delivery device includes the steps of washing and rinsing the sealing members in hot deionized water following by drying the sealing members. The dried sealing members are tumbled with polymeric silicone and then irradiated at a target dose between 2.5 and 4.0 Mrads. The irradiated sealing members are then utilized in a variety of drug delivery devices including syringes, pre-filed syringes, drug cartridges, and needleless injector ampules.
    Type: Grant
    Filed: December 14, 2000
    Date of Patent: November 28, 2006

  • Low silicone plastic prefillable syringe
    Patent number: 6746430
    Abstract: A method for lubricating a sealing member and a medicament chamber in a drug delivery device includes providing lubricating silicone on the surface of the stopper and within the plastic material of the chamber. The stopper preferably is first washed and rinsed in hot deionized water followed by drying. The dried sealing member is then tumbled with polymeric silicone and then irradiated at a target dose between 2.5 to 4.0 Mrads to cause the silicone molecules to bond with the elastomeric material of the stopper. The irradiated sealing members are then loaded in any of a series of chambers including syringes, pre-filled syringes, drug cartridges, and needleless injector ampules. The chamber preferably is made from a plastic material that has been mixed with a lubricating solution such as silicone when the plastic is compounded.
