Suture passer systems and methods for tongue or other tissue suspension and compression
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, comprising:
passing a first tension element proximate to a hyoid bone and around the hyoid bone;
coupling a bone anchor to a mandible, wherein the bone anchor comprises a locking mechanism;
passing the first tension element through the locking mechanism of the bone anchor after passing the first tension element around the hyoid bone;
applying tension to the first tension element to move the hyoid bone; and
securing the locking mechanism, thereby reversibly locking the first tension element with respect to the hyoid bone and the mandible.
2. The method of claim 1 , further comprising:
releasing the locking mechanism; and
adjusting the tension of the first tension element with respect to the hyoid bone after releasing the locking mechanism; and
securing the locking mechanism after adjusting the tension of the first tension element.
3. The method of claim 1 , wherein the bone anchor is coupled near the midline of the mandible.
4. The method of claim 1 , further comprising compressing the tongue to reduce an anterior-posterior dimension of the tongue.
5. The method of claim 1 , further comprising suspending the tongue.
6. The method of claim 1 , further comprising increasing the size of the oral cavity.
7. The method of claim 1 , further comprising utilizing a second tension element to provide tissue suspension.
8. The method of claim 1 , further comprising coupling another tension element to the bone anchor.
9. The method of claim 8 , wherein each tension element is independently adjusted.
10. The method of claim 1 , wherein the first tension element comprises a suture.
11. A method, comprising:
passing a first suture at least partially around a hyoid bone;
attaching a bone anchor to a mandible;
after passing the first suture at least partially around the hyoid bone, suspending the hyoid bone by releasably attaching the first suture to the bone anchor, wherein the first suture can be released from, tensioned, and/or reattached to the bone anchor thereby moving the hyoid bone; and
locking the first suture with respect to the bone anchor.
12. The method of claim 11 , further comprising releasing the first suture from the bone anchor.
13. The method of claim 11 , wherein locking the first suture with respect to the bone anchor comprises passing the first suture through a locking mechanism coupled to the bone anchor.
14. The method of claim 11 , wherein the bone anchor is attached near the midline of the mandible.
15. The method of claim 11 , further comprising compressing the tongue to reduce an anterior-posterior dimension of the tongue.
16. The method of claim 11 , further comprising suspending the tongue.
17. The method of claim 11 , further comprising increasing the size of the oral cavity.
18. The method of claim 11 , further comprising utilizing a second suture to provide tissue suspension.
19. The method of claim 11 , further comprising attaching another suture to the bone anchor.
20. The method of claim 19 , wherein each suture is independently adjusted.
