System and Method For Treatment of Non-Ventilating Middle Ear by Providing a Gas Pathway Through the Nasopharynx
First Claim
Patent Images
1. A method for providing a gas pathway in the middle ear region of a patient, comprising:
- advancing a guide wire into the Eustachian tube (ET) of the patient via the patient'"'"'s nasopharynx;
introducing an endoluminal ET ventilating implant via the patient'"'"'s nasopharynx along the guide wire into the Eustachian tube of the patient;
advancing the implant into the ET adjacent the cartilage and tensor villi palatine or the levator villi palatine muscles, said implant dimensioned for insertion into the ET adjacent the nasopharynx;
tethering the implant to the ET cartilage using a first connector;
tethering the implant to the tensor villi palatine or the levator villi palatine muscles using a second connector;
providing a gas pathway between the ET lumen and the nasopharynx using the implant, the implant being dimensioned and configured to modulate an opening in a gas pathway in communication with the ET lumen and the nasopharynx.

Abstract
Methods and devices for providing a gas pathway between the nasopharynx and the Eustachian tube are provided. One device may include a lumen with a valve. A portion of the valve may be tethered to adjacent muscle. Another portion of the valve may be tethered to adjacent cartilage. When the muscle contracts the valve may open through movement of the tethers, and provide a gas pathway between the nasopharynx and the Eustachian tube.

6. An endoluminal implant for providing a gas pathway between the nasopharynx and the Eustachian tube (ET), comprising:
-
a lumen dimensioned for insertion into the ET at an end adjacent the nasopharynx, through the patient'"'"'s nasopharynx; a valve in fluid communication with the lumen, the valve having a first valve portion and a second valve portion; a first connector portion connected with the first valve portion to tether the implant to the cartilage adjacent the ET; and a second connector portion connected with the second valve portion to tether the implant to the adjacent tensor villi palatine or the levator villi palatine muscles. - View Dependent Claims (7, 8, 9, 10)

15. A method for providing a gas pathway in the middle ear region of a patient, comprising:
-
introducing an implant via the patient'"'"'s nasopharynx into a Eustachian tube (ET) of a patient; coupling the implant to adjacent cartilage to compress a wall of the ET; and providing an intermittent gas pathway between the ET lumen and the nasopharynx using the implant.
