Abstract

A medical device comprising an enclosure defining a cavity for containing agent, a lumen for receiving a pressurized gas, and a barrier positioned between the cavity and the lumen, the barrier including at least one opening for storing agent, wherein rotation of the barrier relative to the lumen establishes fluid communication between the at least one opening and the lumen for delivering agent from the at least one opening to the lumen.

First claim

What is claimed is:

1. A medical device, comprising:
an enclosure defining a cavity for containing agent;
a lumen for receiving a pressurized gas; and
a barrier positioned between the cavity and the lumen, the barrier including a passage extending through the barrier for storing agent received from the enclosure, wherein rotation of the barrier relative to the lumen establishes fluid communication between the passage and the lumen for delivering agent received from the enclosure to the lumen via the passage;
wherein the barrier includes a first opening and a second opening positioned on opposing ends of the barrier, the first opening is connected to the second opening via the passage.

2. The medical device according to claim 1 , wherein a bottom end of the cavity includes a wall adjacent to the barrier, wherein the wall includes a wall opening, wherein the wall opening is located on an area of the wall so that the wall opening is aligned with the first opening via rotation of the barrier.

3. The medical device according to claim 2 , wherein alignment of the wall opening with the first opening permits agent from the enclosure to enter the passage.

4. The medical device according to claim 1 , wherein the enclosure is rotatable relative to the barrier and/or the lumen.

5. The medical device according to claim 1 , wherein the barrier is rotatable relative to the enclosure.

6. The medical device according to claim 1 , wherein the agent remains in the passage until fluid communication between the passage and the lumen is established.

7. The medical device according to claim 1 , wherein the enclosure feeds the passage with agent via gravity.

8. The medical device according to claim 1 , wherein the passage for storing agent feeds the lumen with agent via gravity when fluid communication between the passage and the lumen is established.

9. The medical device according to claim 1 , wherein the lumen is a flexible catheter capable of traversing a tortuous body lumen, and further comprising a source of the pressurized gas.

10. A method of administering an agent via a medical device, comprising:
positioning the medical device, including an enclosure, a barrier, and a lumen, so that a distal end of the lumen is adjacent to a targeted site, wherein the barrier is positioned between the enclosure and the lumen, the enclosure containing the agent, and the barrier including a first opening and a second opening positioned on opposing ends of the barrier, and a passage extending through the barrier between the first opening and the second opening, the passage is configured for connecting the first opening to the second opening and storing the agent received from the enclosure;
providing a pressurized gas to the lumen; and
rotating the barrier relative to the lumen so that fluid communication is established between the passage and the lumen to deliver the agent from the passage to the lumen.

11. The method according to claim 10 , further comprising:
rotating the barrier relative to the lumen so that the passage and the lumen are not in fluid communication after a dose of the agent is delivered from the passage to the lumen.

12. The medical device according to claim 1 , wherein the barrier is configured to seal the first opening, thereby inhibiting the passage from receiving the agent from the cavity.

13. The medical device according to claim 9 , wherein the source of the pressurized gas is configured to supply the pressurized fluid, thereby moving the agent received from the passage through the lumen.

14. A medical device, comprising:
an enclosure storing an agent;
a lumen; and
a barrier positioned between the enclosure and the lumen, the barrier including a first opening, a second opening positioned opposite of the first opening, and a passage extending through the barrier between the first opening and the second opening such that the first opening is in fluid communication with the second opening via the passage;
wherein the barrier is configured to rotate relative to the enclosure and the lumen for establishing fluid communication between the passage and each of the enclosure and the lumen;
wherein, in response to aligning the first opening with the enclosure, the barrier is configured to receive the agent from the enclosure and into the passage via the first opening, and in response to aligning the second opening with the lumen, the barrier is configured to deliver the agent received from the enclosure in the passage into the lumen via the second opening.

15. The medical device according to claim 14 , wherein a bottom wall of the enclosure includes an opening, and the barrier is configured to align the first opening with the opening on the bottom wall of the enclosure in response to rotating the barrier relative to the enclosure and the lumen.

16. The medical device according to claim 14 , wherein a top wall of the lumen includes an opening, and the barrier is configured to align the second opening with the opening on the top wall of the lumen in response to rotating the barrier relative to the enclosure and the lumen.

17. The medical device according to claim 14 , wherein the enclosure feeds the passage with the agent via gravity, and the passage feeds the lumen with the agent via gravity.

18. The medical device according to claim 14 , wherein the agent enters the passage when the first opening is in fluid communication with the enclosure and exits the passage when the second opening is in fluid communication with the lumen.

19. The medical device according to claim 14 , wherein the barrier is configured to seal the first opening, thereby inhibiting the passage from receiving the agent from the enclosure; and
wherein the barrier is configured to seal the second opening, thereby inhibiting the lumen from receiving the agent from the passage.

20. The medical device according to claim 14 , furthering comprising a source of the pressurized gas that is configured to move the agent received from the passage through the lumen.
