Abstract

A container for housing a fluid therapeutic composition includes a rigid housing, a collapsible bag and a seal. The housing has an opening and an interior surface. The interior surface forms a cavity having a volume. The bag is disposed in the housing and is expandable to contact the interior surface of the housing and occupy the entire volume of the cavity when filled with the fluid therapeutic composition. The bag has an opening that is fixed in proximity to the opening of the housing. The seal is configured to prevent air from entering the bag via the bag opening and to prevent air from entering the cavity of the housing via the housing opening.

Claims

1. A container for housing a therapeutic fluid, the container comprising:

a housing having an opening and an interior surface, the interior surface forming a cavity having a volume;

a collapsible bag for containing the therapeutic fluid, wherein the bag is disposed in the housing and expandable to contact the entire interior surface of the housing, wherein the bag has an opening to allow the therapeutic fluid to be introduced into, or exit from, the bag, and wherein the opening of the bag is fixed in proximity to the opening of the housing; and

a seal configured to prevent air from entering the bag via the bag opening and to prevent air from entering the cavity of the housing via the housing opening,

wherein the housing comprises an actuatable vent apparatus configured to allow air to flow between the outside of the housing and the cavity of the housing, when actuated,

wherein the housing is formed from glass and the actuatable vent apparatus comprises a depressable actuator member configured to cause a crack in the glass housing to form a passageway extending from the cavity of the housing to the exterior of the housing, when depressed.

2. A container according to claim 1, wherein the seal comprises a metallic foil layer disposed across the housing opening.

3. A container according to claim 1, wherein the seal comprises a pierceable and resealable septum configured to allow fluid to be introduced into, or withdrawn from, the bag.

4. A container according to claim 1, wherein at least a portion of the seal extends into the bag opening and presses the bag against the interior surface of the housing to fix the bag relative to the housing.

5. A container according to claim 1, wherein the bag is expandable to an unstressed state having a volume that is equal to or greater than the volume of the cavity of the housing.

6. A system comprising:

a container according to claim 1; and

a pumping mechanism operably couplable to the container and configured to pump therapeutic fluid disposed in the bag out of the bag.

7. A system according to claim 6, further comprising a catheter fluidly couplable to the pumping mechanism and configured to deliver the pumped therapeutic fluid to a target location.

8. A system according to claim 7, further comprising a cannula having a lumen for transporting the therapeutic fluid, the cannula being configured to pierce the seal and being operably couplable to the pumping mechanism to allow the lumen to transport the fluid from the bag to the pumping mechanism.

9. A system according to claim 6, wherein the pumping mechanism is a peristaltic pumping mechanism.

10. A system comprising:

a container according to claim 1; and

a flow restrictor operably couplable to the bag and configured to control the rate at which the therapeutic fluid exits the bag.

11. A system according to claim 10, further comprising a cannula having a lumen for transporting the therapeutic fluid, the cannula being configured to pierce the seal and being operably couplable to the flow restrictor to allow the lumen to transport the fluid from the bag to the flow restrictor.

12. A method for delivering therapeutic fluid to a patient, comprising:

piercing the seal of a container according to claim 1 to allow access to the therapeutic fluid in the bag; and

pumping the therapeutic fluid from the bag to a target location of the patient.

13. A method according to claim 12, further comprising venting the housing of the container to allow air to flow from outside the housing to the housing cavity.
