Abstract

Methods and devices are disclosed for manipulating the tongue. An implant is positioned within at least a portion of the tongue and may be secured to other surrounding structures such as the mandible and/or hyoid bone. In general, the implant is manipulated to displace at least a portion of the posterior tongue in an anterior or lateral direction, or to alter the tissue tension or compliance of the tongue. Methods and devices are also disclosed for manipulating other soft tissue structures, including the soft palate and pharyngeal airway.

Claims

1. A method for treating a patient, comprising:

providing a tongue remodeling system, the system comprising at least one tether support and at least one tongue element, the at least one tongue element having at least one expandable tissue anchor joined to at least one tether;

accessing a region about the mandible;

inserting the at least one expandable tissue anchor through a first pathway along the region about the mandible to a tongue;

attaching the at least one tether of the at least one tongue element to the at least one tether support;

positioning the at least one tether support against the mandible; and

fixing the at least one tether support to the mandible.

2. The method for treating a patient as in claim 1, further comprising expanding the at least one expandable tissue anchor joined to the at least one tether.

3. The method for treating a patient as in claim 1, wherein the expandable tissue anchor of the providing step is self-expandable.

4. The method for treating a patient as in claim 1, wherein the expandable tissue anchor comprises a plurality of expandable elongate members.

5. The method for treating a patient as in claim 4, wherein the expandable tissue anchor comprises a plurality of expandable elongate piercing members.

6. The method for treating a patient as in claim 1, wherein the expandable tissue anchor comprises a plurality of expandable tissue-grasping members.

7. The method for treating a patient as in claim 1, wherein the fixing step is performed before the attaching step.

8. The method for treating a patient as in claim 1, wherein at least a portion of the first pathway passes through the mandible.

9. A method for treating a patient, comprising:

providing a tongue element having an attachment end and an expandable tissue-anchoring end;

inserting the expandable tissue-anchoring end into the tongue; and

securing the attachment end of the tongue element to a body structure.

10. The method for treating a patient as in claim 9, wherein the securing of the attachment end of the tongue element to the body structure is performed with an adjustment assembly.

11. The method for treating a patient as in claim 10, wherein the adjustment assembly comprises a moving part, a non-moving part and a movement interface between the moving part and the non-moving part.

12. The method for treating a patient as in claim 9, wherein the expandable tissue-anchoring end comprises one or more tissue-grasping members.

13. The method for treating a patient as in claim 12, wherein the expandable tissue-anchoring end comprises at least two tissue-piercing members.

14. The method for treating a patient as in claim 12, wherein the one or more tissue-grasping members are metallic.

15. The method for treating a patient as in claim 12, wherein the one or more tissue-grasping members are radially expandable elongate members.

16. The method for treating a patient as in claim 9, wherein the expandable tissue-anchoring end comprises a wire coil.

17. The method for treating a patient as in claim 9, wherein the expandable tissue-anchoring end comprises a T-tag.

18. The method for treating a patient as in claim 9, wherein the expandable tissue-anchoring end comprises an expandable polymer plug.

19. The method for treating a patient as in claim 18, wherein the expandable tissue-anchoring end comprises a fibrous or porous expandable polymer plug.

20. The method for treating a patient as in claim 9, wherein the expandable tissue-anchoring end of the providing step comprises a slotted tube having a distal end, a proximal end, and a plurality of expandable middle bands between the distal end and proximal end.

21. The method for treating a patient as in claim 20, wherein the at least one tether is secured to the distal end of the slotted tube.

22. The method for treating a patient as in claim 20, wherein the at least one tether is secured to the proximal end of the slotted tube.

23. The method for treating a patient as in claim 20, wherein the slotted tube is self-expandable.

24. The method for treating a patient as in claim 20, wherein the slotted tube of the providing step is expandable by shortening the slotted tube along its longitudinal length.

25. The method for treating a patient as in claim 24, further comprising the step of pulling the at least one tether to expand the slotted tube.

26. A method for treating a patient, comprising:

accessing a tissue anchor implanted in a tongue, the tissue anchor having a deployment configuration and a removal configuration;

deforming the tissue anchor to the removal configuration; and

withdrawing the tissue anchor from the tongue.

27. The method for treating a patient as in claim 26, wherein the tissue anchor further comprises a proximal tether.

28. The method for treating a patient as in claim 27, further comprising exposing the proximal tether.

29. The method for treating a patient as in claim 28, wherein accessing the tissue anchor implanted in the tongue comprises passing a tubular member along the proximal tether, the tubular member comprising a distal opening, a proximal opening and a lumen therebetween.

30. The method for treating a patient as in claim 29, wherein deforming the tissue anchor to the removal configuration comprises collapsing the tissue anchor into the lumen of the tubular member.

31. The method for treating a patient as in claim 30, wherein withdrawing the tissue anchor from the tongue comprises withdrawing the tubular member from the tongue.

32. The method for treating a patient as in claim 29, wherein the tubular member further comprises a longitudinal slot contiguous with the lumen of the tubular member.

33. The method for treating a patient as in claim 32, wherein the longitudinal slot of the tubular member is contiguous with the distal opening of the tubular member.

34. The method for treating a patient as in claim 33, wherein the tubular member further comprises a movable slot blocking member capable of blocking the distal portion of the longitudinal slot of the tubular member.

35. The method for treating a patient as in claim 34, wherein the movable slot blocking member is a slidable slot blocking member.

36. The method for treating a patient as in claim 34, wherein the movable slot blocking member is a rotatable slot blocking member.

37. The method for treating a patient as in claim 34, wherein the movable slot blocking member is located within the lumen of the tubular member.
