Methods for hyoid suspension
Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.
1. A method of attaching a tension element with respect to a hyoid bone, comprising:
creating a first pathway proximate the hyoid bone;
passing the tension element through the first pathway proximate the hyoid bone and around the hyoid bone;
attaching a bone anchor comprising a locking mechanism to a mandible;
passing the tension element through the locking mechanism after passing the tension element around the hyoid bone;
tensioning the tension element by passing the tension element through at least a portion of the bone anchor, wherein tensioning the tension element thereby moves the hyoid bone; and
activating the locking mechanism, thereby reversibly locking the tension element with respect to the hyoid bone and the mandible.
2. The method of claim 1 , further comprising:
deactivating the locking mechanism; and
adjusting the tension of the tension element with respect to the hyoid bone after deactivating the locking mechanism; and
reactivating the locking mechanism.
3. The method of claim 1 , wherein passing the tension element through the first pathway comprises looping the tension element around the hyoid bone.
4. The method of claim 1 , wherein the method does not comprise tying any knots.
5. The method of claim 1 , further comprising providing the tension element comprising a doubled-over length of a suture.
6. The method of claim 1 , wherein the tension element comprises a suture.
7. The method of claim 1 , wherein the tension element is flexible.
8. The method of claim 1 , wherein the tension element comprises a flattened cross-section.
9. The method of claim 1 , wherein activating the locking mechanism comprises closing a cam lock.
10. The method of claim 1 , wherein passing the tension element through the locking mechanism comprises passing the tension element through an eyelet of the locking mechanism.
11. The method of claim 10 , wherein activating the locking mechanism comprises turning a locking screw with respect to an internally threaded surface, thereby reducing the size of the eyelet.
12. A method of attaching a suture with respect to a hyoid bone to treat a condition of an airway, comprising:
passing a suture loop comprising the suture around the hyoid bone;
attaching a bone anchor to a mandible;
after passing the suture loop around the hyoid bone, suspending the hyoid bone by releasably attaching the suture to the bone anchor, wherein the suture can be released from, tensioned, and/or reattached to the bone anchor thereby moving the hyoid bone in a general superior and anterior direction and locking the suture with respect to the hyoid bone and the mandible without tying any knots.
13. The method of claim 12 , further comprising detaching the suture from the bone anchor.
14. The method of claim 12 , wherein suspending the hyoid bone comprises passing the suture through a locking mechanism connected to the bone anchor, and tensioning the suture.
