Abstract

A method for managing at least one breathing condition may include storing an agent near a patient'"'"'s airway and delivering the agent to the mucosal tissue in the pharyngeal area in a time-released manner during a sleep period. The delivered agent may cause increased contraction of muscle tissue in the pharyngeal area.

Claims

1. A method for managing at least one breathing condition, the method comprising:

storing an agent in nano-spheres configured to dissolve at different rates, the agent operable to cause increased contraction of muscle tissue in the pharyngeal area and including;

acetylcholine;

one or more non-acetylcholine chemicals that slow the rate of degradation of acetylcholine; and

one or more non-acetylcholine chemicals operable to activate nicotinic receptors to cause the contraction of muscle tissue in the pharyngeal area; and

depositing the nano-spheres on the mucosal tissue in the pharyngeal area of a patient, the nano-spheres dissolving at different rates such that the agent is delivered to the pharyngeal area in a time-released manner during a sleep period to cause increased contraction of muscle tissue in the pharyngeal area.

2. A method according to claim 1, wherein the agent is operable to provide elevated levels of acetylcholine in muscle tissue in the pharyngeal area.

3. A method according to claim 2, wherein the agent is operable to provide elevated levels of acetylcholine at neuromuscular junctions associated with the muscle tissue in the pharyngeal area.

4. A method according to claim 1, wherein the one or more non-acetylcholine chemicals that slow the rate of degradation of acetylcholine comprises a non-acetylcholine cholinesterase inhibitor.

5. A method according to claim 1, wherein the agent is stored in a mucosal patch positioned on the mucosal tissue of the pharyngeal area, wherein the mucosal patch contains the agent.

6. A method according to claim 1, wherein the agent is stored in a mucosal patch positioned on the mucosal tissue of the soft palate, wherein the mucosal patch contains the agent.

7. A method according to claim 1, wherein the agent is stored in a mucosal patch positioned on the mucosal tissue of the tongue, wherein the mucosal patch contains the agent.

8. A method according to claim 1, wherein delivering the agent comprises pumping the agent to the mucosal tissue of the pharyngeal area.

9. A method according to claim 1, wherein:

the agent is stored in a reservoir associated with a pump; and

delivering the agent comprises pumping the agent through a catheter using the pump.

10. A method according to claim 1, wherein delivering the agent in a time-released manner comprises the dissolving of a mucosal patch.

11. A method according to claim 1, wherein delivering the agent in a time-released manner comprises intermittently pumping the agent during at least a portion of the sleep period.

12. A method according to claim 1, wherein delivering the agent in a time-released manner comprises continuously pumping the agent during at least a portion of the sleep period.

13. A method according to claim 1, wherein the increased contraction of muscle tissue in the pharyngeal area reduces obstructive sleep apnea.

14. A method according to claim 1, wherein the increased contraction of muscle tissue in the pharyngeal area reduces snoring.

15. A system for managing at least one breathing condition, the system comprising:

a volume of nano-spheres containing an agent and operable to deliver the agent to the mucosal tissue in the pharyngeal area, the agent operable to cause increased contraction of muscle tissue in the pharyngeal area and including;

acetylcholine;

one or more non-acetylcholine chemicals that slow the rate of degradation of acetylcholine; and

one or more non-acetylcholine chemicals operable to activate nicotinic receptors to cause the contraction of muscle tissue in the pharyngeal area; and

the volume of nano-spheres including nano-spheres configured to dissolve at different rates, thereby providing a time-release mechanism operable to control the delivery of the agent to the mucosal tissue in the pharyngeal area during a sleep period to cause increased contraction of muscle tissue in the pharyngeal area during the sleep period.

16. A system according to claim 15, wherein the agent is operable to provide elevated levels of acetylcholine in muscle tissue in the pharyngeal area.

17. A system according to claim 16, wherein the agent is operable to provide elevated levels of acetylcholine at neuromuscular junctions associated with the muscle tissue in the pharyngeal area.

18. A system according to claim 15, wherein the one or more non-acetylcholine chemicals that slow the rate of degradation of acetylcholine comprises a non-acetylcholine cholinesterase inhibitor.

19. A system according to claim 15, wherein, in addition to acetylcholine, the agent further comprises one or more non-acetylcholine chemicals operable to activate nicotinic receptors to cause the contraction of muscle tissue in the pharyngeal area.

20. A system according to claim 15, wherein the agent delivery device comprises a mucosal patch.

21. A system according to claim 15, wherein the agent delivery device comprises a pump.

22. A system according to claim 15, wherein the time-release mechanism comprises a mucosal patch that dissolves during the sleep period.

23. A system according to claim 15, wherein the time-release mechanism comprises a pump that operates during at least portions of the sleep period.

24. A system according to claim 15, wherein the increased contraction of muscle tissue in the pharyngeal area reduces obstructive sleep apnea.

25. A system according to claim 15, wherein the increased contraction of muscle tissue in the pharyngeal area reduces snoring.
