Abstract: A syringe system includes a syringe and a filtration device connected to the syringe for sterilizing and introducing fluid into the syringe. The syringe includes a syringe barrel having a proximal end defining a barrel opening, a distal end defining a delivery opening, a bore extending between the proximal end and the distal end, and a stopper disposed in the bore of the syringe barrel. The filtration device has an inlet and an outlet coupled in fluid communication with the delivery opening at the distal end of the syringe barrel. The filtration device includes a stem and a filter membrane disposed in line with the stem. The filter membrane optionally has a plurality of pores each with a nominal pore size in a range of approximately 0.1 μm to approximately 0.5 μm such that a pharmaceutical fluid can be introduced as a sterilized pharmaceutical fluid into the bore of the syringe barrel by passing through the filtration device.

Abstract: A sterile solution product bag for lyophilizing includes a bladder, a first stem having a first stem inlet end and a first stem outlet end. The first stem outlet end is fluidly connected to the bladder and the first stem inlet end is adapted to receive a liquid. A first filter is disposed in-line with the first stem and includes a first filter membrane, a first filter open end, and a first filter closed end. The first filter closed end is disposed between the first stem inlet end and the first stem outlet end and the first filter open end is disposed in proximity to the first stem inlet end. A second stem having a second stem inlet end fluidly connected to the bladder and a second stem outlet end adapted to receive a vapor. A second filter is disposed within the second stem and includes a filter membrane.

Abstract: A sterile product bag includes a bladder, a stem, a filter, and a vial adaptor. The bladder has a perimeter seal and defining a sterile chamber. The stem extends through the perimeter seal and has an inlet end outside of the perimeter seal and an outlet end in fluid communication with the chamber. The filter is disposed in line with the stem and has a filter membrane with a nominal pore size in a range of approximately 0.1 μm to approximately 0.5 μm. The filter membrane is shaped as a hollow fiber with a wall and pores residing in the wall of the fiber. The vial adaptor includes a sterile hollow cannula, a sheath, and a peelable closure. The cannula is in fluid communication with the chamber of the bladder. The sheath is disposed outside of the bladder and connected to the hollow cannula. The sheath includes an interior cavity into which the hollow cannula extends. The peelable closure extends across an opening of the sheath to seal the interior cavity.
