Abstract

A pharyngeal airway having a pharyngeal wall of a patient at least partially surrounding and defining the airway is treated by selecting an implant dimensioned so as to be implanted at or beneath a mucosal layer of the pharyngeal wall and extending transverse to said wall. The implant has mechanical characteristics for the implant, at least in combination with a fibrotic tissue response induced by the implant, to stiffen said pharyngeal wall to resist radial collapse. The implant is implanted into the pharyngeal wall transverse to a longitudinal axis of the airway.

Claims

1. An apparatus for treating sleep apnea, comprising:

a curved implant made of a biocompatible material, the curved implant having an open concave configuration, the curved implant having a curved length from a first end to a second end that extends 180 degrees around a circumference of a pharyngeal airway of a human;

the curved implant being sized and structured to be placed in or radially outwardly from lateral and posterior walls of the pharyngeal airway with the length of the curved implant extending generally laterally across the posterior wall and, when so placed, being effective in treating sleep apnea.

2. The apparatus of claim 1, wherein the curved implant is made of braided biocompatible material.

3. The apparatus of claim 1, wherein the curved implant is C-shaped.

4. The apparatus of claim 1, wherein the curved implant is sized and structured to be placed below a soft palate of the human.

5. The apparatus of claim 1, wherein the curved implant is made of an elastic material biased to resist radial collapse.

6. The apparatus of claim 1, wherein the open concave configuration of the curved implant is defined by only a single elongated element having a curvature extending from the first end to the second end.

7. An apparatus for treating at least one of sleep apnea and snoring, comprising:

an appliance having only a single elongated element extending between first and second end portions, the appliance being sized for introduction into an oropharyngeal region of a human and deployable in a C-shaped deployed configuration in which the elongated element extends generally laterally across the posterior wall and the first and second end portions bear against and provide an opening force against lateral walls of the oropharyngeal region.

8. The apparatus of claim 7, wherein, in the C-shaped deployed configuration, the first and second end portions define a gap therebetween.

9. The apparatus of claim 7, wherein the appliance comprises biocompatible material.

10. A method for treating sleep apnea, the method comprising the step of:

providing an appliance made of a biocompatible material below a soft palate of a human in or radially outwardly from lateral and posterior walls of an oropharyngeal region of the human, the appliance having a laterally positioned element providing an opening force against the lateral walls of the oropharyngeal region.

11. The method of claim 10, wherein the appliance, when located in the oropharyngeal region, is effective in maintaining patency of the oropharyngeal region during natural sleep without causing substantial interference with at least one natural function of an epiglottis.

12. The method of claim 10, wherein the step of providing includes inserting the appliance into the oropharyngeal region through a mouth of a patient.

13. The method of claim 10, wherein the step of providing includes placing the appliance at least partially in or beneath a mucosal layer of the lateral and posterior walls of the oropharyngeal region.

14. The method of claim 10, wherein the step of providing includes placing the appliance completely across the posterior wall of the oropharyngeal region.

15. The method of claim 10, wherein the appliance has a lateral dimension and a longitudinal dimension perpendicular to the lateral dimension that is less than the lateral dimension when the appliance is so provided.

16. The method of claim 10, wherein the appliance is sized and structured so that the laterally positioned element extends across the posterior wall and at least a portion of one of the lateral walls when the appliance is so provided.

17. The method of claim 10, wherein the appliance is sized and structured so that the laterally positioned element extends across the posterior wall and at least a portion of both the lateral walls when the appliance is so provided.

18. The method of claim 10, wherein the appliance has an open concave configuration when so provided.

19. The method of claim 10, wherein the appliance is made of an elastic material biased to resist radial collapse.

20. The method of claim 10, wherein the step of providing the appliance includes providing the appliance having the laterally positioned element with a length that provides the opening force against the lateral walls of the oropharyngeal region.
