Combination sleep apnea treatment
View Patent ↗A method for treating a patient diagnosed with obstructive sleep apnea includes identifying a patient as having sleep apnea susceptible to a first positive airway treatment which is at a first operating pressure level in excess of that which is otherwise tolerable to the patient. The patient is treated with an airway treatment selected to alter a portion of an airway tissue of the patient. The patient is then treated with a second positive airway pressure treatment at a second pressure level, which is below the pressure threshold.
1. A method for treating a patient diagnosed with obstructive sleep apnea, said method comprising:
identifying a patient as having sleep apnea susceptible to a first positive airway treatment at a first pressure level sufficiently high to contribute to an unsatisfactory patient compliance with said first airway treatment;
said first positive airway treatment including generating an air flow at said first pressure and admitting said first air flow into said patient's airway with said first pressure estimated to be sufficient to treat said apnea;
treating said patient with an airway treatment selected to alter a portion of an airway tissue of said patient;
said airway treatment consisting essentially of placement of a member completely embedded within said airway tissue and selected to alter a stiffness of said airway tissue to an increased stiffness sufficient to increase a resistance of said tissue to deformation and with said airway treatment alone insufficient to fully treat said apnea;
treating said patient with a second positive airway treatment while said member is embedded within said airway tissue and with said second positive airway treatment at a second pressure lower than said first pressure and selected to contribute to an enhanced patient compliance relative to said first airway treatment;
said second positive airway treatment including generating an air flow at said second pressure, and admitting said second air flow into said patient's airway with said second positive airway treatment in combination with said altered stiffness treating said apnea; and
retaining said member embedded within said tissue following discontinuance of said second positive airway treatment.
2. A method according to claim 1 wherein said airway tissue is a palatal tissue of said patient.
3. A method according to claim 1 wherein said airway tissue is a nasal tissue of said patient.
4. A method according to claim 1 wherein said airway tissue is a tongue tissue of said patient.
5. A method according to claim 1 wherein said airway tissue is a pharyngeal wall tissue of said patient.
6. A method according to claim 1 wherein said airway treatment includes placement of a fibrosis-inducing member in said tissue with said fibrosis-inducing member selected to induce formation of fibrosis in said airway tissue following said placement.
7. A method according to claim 1 wherein said airway treatment includes placement of a stiffening member in said tissue with said stiffening member having a material stiffness selected to increase a stiffness of said airway tissue following said placement.
8. A method according to claim 1 wherein said airway treatment includes placement of a magnetic field-responsive material in said tissue with said magnetic field-responsive material selected to urge said airway tissue to maintain a patency of an airway of said patient in response to a cooperating magnetic field.
9. A method according to claim 1 wherein said second pressure is at least 11 cm H 2 O lower than said first pressure.
