Abstract

A method and apparatus for treating snoring of a patient includes providing an implant for altering a dynamic response of a soft palate of the patient to airflow past the soft palate. The implant is embedded in the soft palate to alter the dynamic response. For example, the implant has a mass, stiffness or dampening sufficient to alter the dynamic response following the implantation without substantially impairing a function of the soft palate to close a nasal passage of the patient during swallowing.

Claims

1. A method for treating snoring of a patient, said method comprising:

selecting an implant dimensioned so as to be implanted into a soft palate of said patient, said implant having a stiffness selected for said implant to alter a dynamic response of said soft palate of said patient in response to air flow past said soft palate without application of force external to said soft palate, and said implant having a longitudinal dimension and a narrower transverse dimension and said implant being flexible along said longitudinal dimension; and

implanting said implant within said soft palate to alter said dynamic response with said longitudinal dimension extending in a path generally from a front of said patient toward a back of said patient.

2. A method according to claim 1 wherein said implant is formed at least in part from nitinol.

3. A method according to claim 1 wherein said implant includes a surface adapted for tissue in-growth.

4. A method according to claim 3 wherein at least a portion of said implant is a polyester.

5. A method according to claim 1 wherein said implant includes a radiopaque marking.

6. A method according to claim 1 wherein said implant is an injectable polymer injected into said soft palate.

7. A method according to claim 1 wherein said implant is completely implanted into said soft palate.

8. An apparatus for treating snoring of a patient suffering from snoring attributable, at in least in part, to a snoring sound generating oscillation of a soft palate of said patient in response to airflow past said soft palate and where said soft palate has a characteristic dynamic response to said airflow prior to treatment, said apparatus comprising:

an implant of bio-compatible material sized to be embedded within said soft palate;

said implant having a stiffness for said implant, without application of force external to said soft palate, to alter said dynamic response without substantially impairing a function of said soft palate to close a nasal passage of said patient from a pharynx of said patient during swallowing; and

said implant being flexible along said longitudinal dimension, and said implant not susceptible to substantial expansion and contraction in response to contraction and relaxation of muscles of the soft palate.

9. An implant according to claim 8 wherein said implant has a longitudinal dimension and a smaller transverse dimension, said implant being flexible along said longitudinal dimension.

10. An apparatus according to claim 8 wherein said implant is formed at least in part from nitinol.

11. An apparatus according to claim 8 wherein said implant includes a surface adapted for tissue in-growth.

12. An apparatus according to claim 11 wherein at least an outer surface of said implant is a polyester.

13. An apparatus according to claim 8 wherein said implant includes a radiopaque marking.

14. An apparatus according to claim 8 wherein said implant is an injectable polymer injected into said soft palate.

15. An apparatus according to claim 8 wherein said implant is sized to be completely implanted into said soft palate.
