  • Three-position plungers, film coated plungers and related syringe assemblies
    Patent number: 11857771
    Abstract: A three-position plunger is provided including a sleeve having an opening at a distal end, a pre-load cavity proximal to and in communication with the opening, a first cavity proximal to and in communication with the pre-load cavity, a second cavity proximal to and in communication with the pre-load cavity, and at least one rib. The rib(s) is generally aligned with the first cavity. The plunger further includes an insert configured to be displaced from the pre-load cavity to the first cavity and from the first cavity to the second cavity. The insert is configured to provide support for the compression of the rib(s) when the insert is positioned in the first cavity.

  • Convertible plungers, film coated plungers and related syringe assemblies
    Patent number: 10561795
    Abstract: A convertible plunger is provided comprising an internal portion and a generally cylindrical exterior surface. At least a portion of the exterior surface is maintained in an initial expanded state by a property of the internal portion. The expanded state is reducible to a constricted state by an operation that is applied to the internal portion of the plunger to alter the property. A film coating may also be applied to a sidewall of the sleeve to reduce a sliding friction between the sleeve and barrel. A film coating may also be applied to a nose cone of the plunger to provide a barrier between the plunger and product in the barrel.
