Implantable obstructive sleep apnea sensor
Systems and methods for detecting an obstructive sleep apnea event are disclosed herein. The systems and methods may use an electrical output generating ionic polymer metal composite sensor attached to a region in an airway passage in an oral cavity. The electrical output may be wirelessly transmitted as a signal for indication of an obstructive sleep apnea event. The signal may be further analyzed for treatment of the obstructive sleep apnea event.
1. A method for sensing obstructive sleep apnea in a patient, comprising:
attaching an ionic polymer metal composite (IPMC) sensor at one of a hard palate and a soft palate of an airway passage in an oral cavity of the patient;
electrically coupling a transmitter device to the IPMC sensor;
placing the transmitter device at a location away from the hard palate and the soft palate;
generating an electrical output from the IPMC sensor when a change in a shape in the oral cavity occurs;
transmitting a signal from the transmitter device which is based on the generated electrical output from the IPMC sensor;
wherein the signal is transmitted by a wireless transmitter component of the transmitter device that is electrically coupled to the IPMC sensor and located away from the hard palate and the soft palate.
2. The method of claim 1 additionally comprising analyzing the transmitted signal.
3. The method of claim 2 wherein analyzing includes creating a predictive algorithm based on the transmitted signal.
4. The method of claim 3 additionally comprising sending a control signal to a obstructive sleep apnea treatment device based on the analyzed transmitted signal.
5. The method of claim 1 additionally comprising translating the generated electrical output into the signal.
6. The method of claim 5 wherein the signal is digital.
7. The method of claim 5 wherein the signal is analog.
8. The method of claim 1 wherein the transmitter device includes a capacitor.
9. The method of claim 1 wherein the transmitter device transmits the signal according to a wireless transmission standard.
10. The method of claim 1 ,
wherein the transmitter device includes a battery.
11. The method of claim 10 wherein at least a portion of the transmitter device is detachable from the IPMC sensor for recharging the battery.
12. The method of claim 1 additionally comprising:
receiving the signal at a wireless receiver; and
recording the signal at a control device electronically coupled to the wireless receiver.
13. The method of claim 12 wherein the control device additionally performs an analysis of the signal.
14. The method of claim 1 wherein the IPMC sensor includes an electro active polymer material.
15. The method of claim 1 wherein the IPMC sensor is configured as an elongated strip.
16. The method of claim 1 wherein the IPMC sensor is placed on the soft palate.
17. The method of claim 1 wherein the IPMC sensor is placed on the soft palate using an adhesive.
18. The method of claim 1 wherein the IPMC sensor is implanted into the soft palate.
19. The method of claim 1 wherein signal is an amplified analog signal.
