1. An endoluminal implant for providing a gas pathway between a nasopharynx and a Eustachian tube (ET) of a patient, the endoluminal implant comprising:
(a) a body dimensioned for insertion into the ET, wherein the body defines a lumen; and
(b) a valve configured to modulate opening and closing of the lumen in response to movement of tissue associated with the ET, wherein the valve comprises:
(i) a first valve portion; and
(ii) a second valve portion,
wherein the first and second valve portions are movable relative to one another between a closed state in which the valve portions are configured to sealingly engage one another to thereby restrict flow of gas through the lumen, and an open state in which the valve portions are configured to separate to thereby permit flow of gas through the lumen.
