Abstract

A system for the treatment of obstructive sleep apnea packaged in a collar assembly with remote electrodes which can be worn by a patient without any special preparation. The collar assembly has an adjustable attachment means, such as hook and latch, to accommodate variations in neck size. The collar assembly is properly oriented using variations in physical shape and/or color. An optional feedback system permits the patient to readily verify proper orientation. The remote electrodes may be conveniently maintained in position using a mouthpiece or other means. Radio frequency signals are sent from the collar assembly to the remote electrodes to provide the therapy upon detection of an apnea event.

Claims

1. An apparatus for treating obstruction of an upper air passageway of a patient comprising:

a. means for sensing onset of an obstructive sleep apnea episode;

b. means coupled to said sensing means for generating muscle stimulating signals;

c. electrode means for transferring said muscle stimulating signals to muscle tissue of said upper air passageway of said patient;

d. means coupled to said generating means and said electrode means for coupling said muscle stimulating signals from said generating means to said electrode means; and

e. means attached to said sensing means, said generating means, and said coupling means for maintaining said sensing means, said generating means, and said coupling means in proximity to said patient.

2. An apparatus according to claim 1 wherein said coupling means comprises a radio frequency transmitter.

3. An apparatus according to claim 2 wherein said coupling means further comprises a radio frequency antenna coupled to said radio frequency transmitter.

4. An apparatus according to claim 3 wherein said maintaining means comprises a collar.

5. An apparatus according to claim 4 wherein said collar includes positioning means.

6. An apparatus according to claim 5 wherein said sensing means comprises an audio sensor.

7. An apparatus according to claim 5 wherein said sensing means comprises an activity sensor.

8. An apparatus according to claim 5 wherein said sensing means comprises an oximeter.

9. An apparatus according to claim 5 wherein said sensing means comprises an air flow meter.

10. A method of treating obstructive sleep apnea comprising:

a. generating an electrical muscle stimulation signal;

b. transmitting said electrical muscles stimulation signal using a radio frequency signal;

c. receiving said radio frequency signal at a remote electrode means; and

d. using said electrode means to transfer said muscle stimulating signals to muscle tissue of said upper air passageway of a patient.

11. A method according to claim 10 further comprising sensing onset of an apnea event.

12. A method according to claim 11 further comprising initiating said generating step in response to said sensing of said onset of said apnea event.

13. An apparatus for treating a patient comprising:

a. means for generating muscle stimulating signals;

b. electrode means for transferring said muscle stimulating signals to muscle tissue of said upper air passageway of said patient;

c. means coupled to said generating means and said electrode means for coupling said muscle stimulating signals from said generating means to said electrode means; and

d. means attached to said generating means and said coupling means for maintaining said generating means and said coupling means in proximity to said patient.

14. An apparatus according to claim 13 wherein said coupling means further comprises a radio frequency transmitter.
