Abstract

An esophageal atresia bridge device including a proximal anchor, a distal anchor, and a brace extending between the proximal anchor and the distal anchor. The brace permits the proximal anchor to move toward the distal anchor to apply a controlled tension that pulls the esophagus together and stretches the esophagus over time. A method of treating esophageal atresia may include inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region, and rotating the rotatable member relative to the elongate member to longitudinally move the distal end of the elongate member relative to the rotatable member in order to apply a force to a proximal pouch of the patient's esophagus.

First claim

What is claimed is:

1. A method of treating esophageal atresia, comprising:
inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region; and
rotating the rotatable member relative to the elongate member, wherein rotation of the rotatable member relative to the elongate member causes longitudinal movement of the distal end of the elongate member relative to the rotatable member in order to apply a force to a proximal pouch of the patient's esophagus.

2. The method of claim 1 , wherein the elongate member includes a threaded region threadably engaging the threaded region of the rotatable member.

3. The method of claim 2 , wherein the threaded region of the elongate member extends distally from the rotatable member.

4. The method of claim 3 , wherein the rotatable member includes a threaded lumen including the threaded region of the rotatable member, wherein the threaded region of the elongate member extends into the threaded lumen.

5. The method of claim 1 , wherein the force applied to the proximal pouch draws the proximal pouch closer to a distal pouch of the patient's esophagus over time.

6. The method of claim 5 , further comprising, surgically attaching the proximal pouch to the distal pouch.

7. The method of claim 1 , wherein the elongate member includes an enlarged portion for engaging the proximal pouch.

8. The method of claim 1 , wherein the rotatable member includes a radially extending flange coupled thereto.

9. The method of claim 8 , wherein the radially extending flange is rotatable relative to the rotatable member.

10. The method of claim 1 , wherein the elongate member applies a force to a distal pouch of the patient's esophagus.

11. A method of treating esophageal atresia, comprising:
inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region;
applying a force to a proximal pouch of the patient's esophagus with a portion of the esophageal atresia device; and
rotating the rotatable member relative to the elongate member, wherein rotation of the rotatable member relative to the elongate member increases the force applied to the proximal pouch of the patient's esophagus by the portion of the esophageal atresia device.

12. The method of claim 11 , wherein the elongate member includes a threaded region threadably engaging the threaded region of the rotatable member.

13. The method of claim 12 , wherein the threaded region of the elongate member extends distally from the rotatable member.

14. The method of claim 13 , wherein the rotatable member includes a threaded lumen including the threaded region of the rotatable member, wherein the threaded region of the elongate member extends into the threaded lumen.

15. The method of claim 11 , wherein the force applied to the proximal pouch draws the proximal pouch closer to a distal pouch of the patient's esophagus over time.

16. The method of claim 15 , further comprising, surgically attaching the proximal pouch to the distal pouch.

17. A method of treating esophageal atresia, comprising:
inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region; and
drawing a proximal pouch of the patient's esophagus closer to a distal pouch of the patient's esophagus via rotation of the rotatable member relative to the elongate member;
wherein the elongate member includes a threaded region threadably engaging the threaded region of the rotatable member.

18. The method of claim 17 , wherein the threaded region of the elongate member extends distally from the rotatable member.

19. The method of claim 18 , wherein the rotatable member includes a threaded lumen including the threaded region of the rotatable member, wherein the threaded region of the elongate member extends into the threaded lumen.
