First Claim
Patent Images
1. A method for providing a gas pathway and introducing a therapeutic substance in the middle ear region of a patient, comprising:
- (a) introducing an endoluminal implant via the patient'"'"'s nasopharynx into a Eustachian tube (ET) of the patient, wherein the endoluminal implant;
i. contains the therapeutic substance; and
ii. is configured to elute the therapeutic substance into tissue of the ET;
(b) providing an intermittent gas pathway between a lumen of the ET and the nasopharynx using the endoluminal implant; and
(c) eluting the therapeutic substance into the tissue of the ET that is adjacent to the endoluminal implant.

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.

10. An endoluminal implant for providing a gas pathway between a nasopharynx and Eustachian Tube (ET) of a patient and introducing a therapeutic substance into the ET of the patient, the endoluminal implant comprising:
-
(a) a lumen dimensioned for insertion into the ET, the lumen containing the therapeutic substance; (b) a valve in fluid communication with the lumen, the valve having a first valve portion and a second valve portion; (c) a first connector portion connected with the first valve portion to tether the implant to cartilage adjacent to the ET; (d) a second connector portion connected with the second valve portion to tether the implant to adjacent tensor villi palatine or the levator villi palatine muscles; wherein the first connector portion comprises a first tether configured to span across the cartilage and compress mucosa in a lumen of the ET to secure the first valve portion with the cartilage. - View Dependent Claims (11, 12, 13, 14)

15. An endoluminal implant for providing a gas pathway and introducing a therapeutic substance in the middle ear region of a patient, the endoluminal implant comprising an elongated spring member dimensioned for insertion into a Eustachian tube (ET) of the patient, wherein the elongated spring member comprises the therapeutic substance and is configured to:
-
(a) apply a force to modulate an opening in a gas pathway in communication with a lumen of a Eustachian Tube (ET) and a nasopharynx of the patient; and (b) deliver the therapeutic substance to adjacent tissue. - View Dependent Claims (16, 17, 18, 19, 20)
