Abstract: A product bag includes a bladder and an elongated filtration device. The bladder includes opposing first and second film layers defining a product chamber. The first and second film layers are sealed together along a perimeter seal extending along at least a portion of a perimeter of the bladder. The elongated filtration device includes a housing, a filtration membrane disposed in the housing, an inlet adapted for receiving a fluid to be filtered, and an outlet in fluid communication with the product chamber. A majority of the elongated filtration device is embedded between the first and second film layers of the perimeter seal of the bladder to provide for a compact form factor.

Abstract: A medical product includes a bladder, a filtration device, and a sterile product concentrate. The bladder has a perimeter seal and defining a sterile chamber. The filtration device includes a stem and a filter membrane disposed in line with the stem. The stem extends through the perimeter seal and has an inlet end accessible from outside of the perimeter seal and an outlet end in fluid communication with the sterile chamber. The filter membrane can have a nominal pore size in a range of approximately 0.1 μm to approximately 0.5 μm, wherein the filter membrane is shaped as a hollow fiber with a wall and pores residing in the wall of the fiber. The sterile product concentrate is disposed in the sterile chamber and adapted to be reconstituted by the introduction of a pharmaceutical fluid into the chamber through the filtration device.

Abstract: A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

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.

Abstract: A method of providing filled product bags of sterile and particulate-free fluid includes securing a product bag to one of a plurality of movable cradles, wherein the product bag has a bladder, a stem fluidly connected to an opening of the bladder, and a filter disposed in-line with the stem. After securing the bag, an inlet of the stem is connected to an outlet of a nozzle assembly and at least partially filling the product bag with a fluid through a nozzle of the nozzle assembly to create a filled product bag, wherein filling the product bag includes passing the fluid through the filter and into the bladder. After filling, the stem of the filled product bag is sealed at a location below the filter. The stem is cut at a location above the seal and below the filter. The method including performing an integrity test on the filter, removing the filled product bag from the cradle, and depositing the filled product bag into a first bin for rejected bags if the filter fails the integrity test and a second bin for accepted bags if filter passes the integrity test.
