Abstract

Devices, systems and methods employ magnetic force to resist tissue collapse in targeted pharyngeal structures and individual anatomic components within the pharyngeal conduit during sleep.

Claims (12)

1. A system comprising a first magnetically interactive material sized and configured for placement in or on a tongue, and a second magnetically interactive material sized and configured for placement in a desired relationship with the tongue to magnetically interact with the first magnetically interactive material by repelling the first magnetically interactive material to stabilize a preferred orientation of the tongue,

wherein at least one of the first and second magnetically interactive materials includes at least one source of magnetism having a periphery and a flexible polymer matrix including a protective material encapsulating the at least one source of magnetism, the flexible polymer matrix including an edge region extending beyond the periphery of the source of magnetism to allow flexure of the flexible polymer matrix relative to the source of magnetism.

2. A method comprising placing a first magnetically interactive material in or on a tongue, and placing a second magnetically interactive material in a desired relationship with the tongue to magnetically interact with the first magnetically interactive material by repelling the first magnetically interactive material, stabilizing a preferred orientation of the tongue by the magnetic interaction.

3. A method according to claim 2 wherein the second magnetically interactive material is placed in an airway.

4. A method according to claim 2 wherein the second magnetically interactive material is implanted in tissue in an airway.

5. A method according to claim 2 wherein the second magnetically interactive material is placed in or on a soft tissue region defining a portion of a pharyngeal conduit or a pharyngeal wall or combinations thereof.

6. A method according to claim 2 wherein the second magnetically interactive material is implanted in a soft tissue region defining a portion of a pharyngeal conduit or a pharyngeal wall or combinations thereof.

7. A method according to claim 2 wherein first magnetically interactive material is implanted within tongue tissue.

8. A method according to claim 7 wherein the second magnetically interactive material is implanted in tissue in an airway.

9. A method according to claim 8 wherein the second magnetically interactive material is implanted in a soft tissue region defining a portion of a pharyngeal conduit or a pharyngeal wall or combinations thereof.

10. A method according to claim 2 wherein first magnetically interactive material is implanted within tongue tissue in a posterior region of the tongue.

11. A method according to claim 2 wherein the first magnetically interactive material is implanted entirely within tongue tissue.
