Airway implants and methods and devices for insertion and retrieval
Embodiments of the present invention relate to methods and devices for the treatment of airway obstruction, such as obstructive sleep apnea, and devices and methods that facilitate insertion and retrieval of the same. In one embodiment, disclosed is a tissue tensioner that includes an elongate flexible tether having a first end and a second end, a bone anchor configured to be connected to a patient's mandible, a tissue ingrowth implant configured to be implanted in a patient's tongue and connected to the second end of the tether, and an adjustment mechanism configured to be held by the bone anchor adjacent the patient's mandible and configured to receive the first end of the tether and configured to adjust tension in the flexible tether between the patient's mandible and tongue. Various anchors, tethers, securement mechanisms, and adjustment mechanisms that can be used with glossal and palatal remodeling systems are also disclosed.
1. A tissue tensioner for treating a condition of a patient's airway, said tissue tensioner comprising:
an elongate flexible tether having a first end and a second end;
a bone anchor configured to be connected to a patient's mandible;
a tissue ingrowth implant, configured to be implanted in a patient's tongue, the tissue ingrowth implant being connected to the second end of the tether; and
an adjustment mechanism configured to be held by the bone anchor adjacent the patient's mandible, the adjustment mechanism configured to receive the first end of the tether and configured to adjust tension in the flexible tether between the patient's mandible and the patient's tongue.
2. The tensioner of claim 1 , wherein the tether is an active variable length tether.
3. The tensioner of claim 1 , wherein the tether has a coating tending to cause tissue ingrowth.
4. The tensioner of claim 1 , wherein the adjustment mechanism comprises a rotational spool assembly.
5. A tissue tensioner for treating a condition of a patient's airway, said tissue tensioner comprising:
an elongate flexible tension member;
a first portion of the tension member configured to be secured relative to a body tissue and a second portion of the tension member comprising a tissue ingrowth material configured to be secured to a portion of a tongue; and
an adjustment mechanism configured to adjust tension in the tension member between the body tissue and said portion of a tongue.
6. The tensioner of claim 5 , wherein the first portion of the tension member is connected to a bone anchor.
7. The tensioner of claim 5 , wherein the first portion of the tension member is connected to a tissue anchor.
8. The tensioner of claim 5 , wherein the tissue ingrowth material is a woven material comprising a single strand.
9. The tensioner of claim 5 , further comprising a cap element covering at least a portion of the tissue ingrowth material.
10. The tensioner of claim 9 , wherein the cap element comprises a radioopaque portion.
11. A method for treating airway obstruction comprising:
placing a tissue tensioner within a patient's tongue, the tensioner comprising:
a flexible elongate tension member having a first portion configured to be secured relative to a body tissue and a second portion that is connected to a tissue ingrowth material; and
an adjustment mechanism configured to adjust tension in the tension member between the body tissue and the tissue ingrowth material;
securing the first portion relative to a body tissue and implanting the tissue ingrowth material within a portion of the tongue; and
adjusting the tension of the tension member by manipulating the adjustment mechanism.
12. The method of claim 11 , wherein the first portion is secured relative to a patient's mandible using a bone anchor.
13. The method of claim 11 , wherein the first portion is secured to tongue tissue using a tissue anchor.
14. The method of claim 11 , wherein the tissue ingrowth implant comprises a woven material comprising a single strand.
15. A tissue tensioner for treating a condition of a patient's airway comprising:
an elongate flexible tension member comprising a first portion and a second portion, wherein the first portion of the tension member is securable relative to a body tissue and wherein the second portion is connected to a tissue ingrowth material structured to be implanted in soft tissue; and
means for adjusting the tension between the tissue ingrowth material and the body tissue when the first portion is secured relative to the body tissue and the tissue ingrowth material is implanted in soft tissue.
16. The tensioner of claim 15 , wherein the first portion of the tension member is configured to be connected to a bone anchor.
17. The tensioner of claim 15 , wherein the first portion of the tension member is configured to be connected to a tissue anchor.
