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 mechanical characteristics for said implant, at least in combination with a fibrotic tissue response induced by said implant, to alter a dynamic response of said soft palate of said patient to air flow past said soft palate without application of force external to said soft palate;

implanting said implant into said soft palate to alter said dynamic response.

2. A method according to claim 1 comprising providing said implant to have a mass sufficient to alter said dynamic response following said implantation 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.

3. A method according to claim 1 comprising providing said implant to dampen said dynamic response following said implantation 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.

4. A method according to claim 1 comprising providing said implant to stiffen said soft palate to alter said dynamic response following said implantation 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.

14. A method according to claim 1 wherein said implant is dimensioned to expand a geometry of the soft palate by an amount sufficient to alter an aerodynamic response to airflow over the soft palate.

5. A method 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 mechanical characteristics for said implant, at least in combination with a fibrotic tissue response induced by 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, said implant further dimensioned so as to not substantially increase a bulk of said soft palate following implantation of said implant into said soft palate; 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.

12. A method according to claim 5 wherein said implant is configured to a greater deflection resistance in one direction than in an opposite direction.

13. A method according to claim 5 wherein said implant has a spring constant selected to stiffen said palate.

6. 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 mechanical characteristics for said implant, at least in combination with a fibrotic tissue response induced by 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 said implant having a stiffness selected to stiffen said soft palate to alter said dynamic response following said implantation 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, said implant further dimensioned so as to not substantially increase a bulk of said soft palate following implantation of said implant into said soft palate;

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.

7. A method according to claim 6 wherein said stiffness is adjustable.

8. A method according to claim 7 wherein said implant includes a housing having an interior space to receive a selected one of a plurality of inserts of varying stiffness.

9. A method according to claim 7 wherein said implant includes a housing having an interior space to receive a selected number of a plurality of inserts.

10. A method according to claim 7 wherein said implant is a bladder having an enclosed interior volume to receive a selected amount of a fluid to alter a stiffness of said bladder in response to an amount of said fluid in said volume.

11. A method according to claim 7 wherein said implant is a bladder having an enclosed interior volume containing a fluid with a stiffness of said bladder adjustable in response to a stiffening agent admitted to said fluid.

15. 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 mechanical characteristics for said implant, at least in combination with a fibrotic tissue response induced by said implant and 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.

16. An apparatus according to claim 15 wherein said implant includes a surface adapted for tissue in-growth.

17. An apparatus according to claim 16 wherein at least an outer surface of said implant is a polyester.

18. An apparatus according to claim 15 wherein said implant is elastic to be biased toward a rest position following bending of said implant along said longitudinal axis.

19. An apparatus according to claim 15 wherein said implant includes a radiopaque marking.

20. An apparatus according to claim 15 wherein said implant includes a housing with inserts for varying a stiffness of said implant.

21. An apparatus according to claim 15 wherein said implant is an injectable polymer injected into said soft palate.
