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 of treating a patient, comprising:
passing a tension element to form an arc around a hyoid bone;
coupling a bone anchor to a mandible;
applying tension to the tension element; and
reversibly securing the tension element to the bone anchor with the tension element forming the arc around the hyoid bone and with tension applied to the tension element, thereby suspending the hyoid bone relative to the mandible.
2. The method of claim 1 , wherein passing the tension element to form the arc around the hyoid bone further comprises utilizing a passer tool.
3. The method of claim 1 , wherein reversibly securing the tension element comprises rotating a locking mechanism.
4. The method of claim 1 , further comprising passing the tension element though an eyelet of the bone anchor.
5. The method of claim 1 , further comprising passing the tension element though an enlarged proximal head of the bone anchor.
6. The method of claim 1 , further comprising releasing the tension element and adjusting the tension of the tension element.
7. The method of claim 6 , wherein releasing the tension element comprises rotating a locking mechanism.
8. The method of claim 1 , wherein reversibly securing the tension element relative to the bone anchor with the tension element forming the arc around the hyoid bone and with tension applied to the tension element, thereby suspending the hyoid bone relative to the mandible, increases the size of an airway to relieve airway obstruction.
9. The method of claim 1 , wherein reversibly securing the tension element to the bone anchor with the tension element forming the arc around the hyoid bone and with tension applied to the tension element, thereby suspending the hyoid bone relative to the mandible, compresses or suspends tissue that obstructs an airway of the patient.
10. The method of claim 1 , comprising passing the tension element to form the arc around the hyoid bone and then coupling the bone anchor to the mandible.
11. A method of treating a patient, comprising:
passing a tension element at least partially around a hyoid bone;
pulling the tension element to adjust a position of the hyoid bone relative to a mandible; and
reversibly securing the tension element to a bone anchor attached to the mandible, thereby suspending the hyoid bone relative to the mandible.
12. The method of claim 11 , wherein passing the tension element at least partially around the hyoid bone further comprises utilizing a tool to pass the tension element.
13. The method of claim 11 , wherein reversibly securing the tension element comprises rotating a locking mechanism.
14. The method of claim 11 , further comprising passing the tension element though an opening in the bone anchor.
15. The method of claim 11 , further comprising passing the tension element though a proximal portion of the bone anchor.
16. The method of claim 11 , further comprising releasing tension element and adjusting the tension element.
17. The method of claim 16 , wherein releasing the tension element comprises rotating a locking mechanism.
18. The method of claim 11 , wherein the method treats obstructive sleep apnea.
19. The method of claim 11 , wherein reversibly securing the tension element to the bone anchor attached to the mandible, thereby suspending the hyoid bone relative to the mandible, enlarges an airway of the patient.
20. The method of claim 11 , wherein reversibly securing the tension element to the bone anchor attached to the mandible, thereby suspending the hyoid bone relative to the mandible, compresses or suspends tissue that obstructs an airway of the patient.
