Patulous Eustachian Tubes (pET) are a pathology of the tube that connects a person's middle ear to the nasopharynx. The function of this tube is to provide pressure relief periodically throughout a day. Additionally, since the tube is closed in its resting state, it insulates the middle ear from the noises in the nasopharynx such as breathing, swallowing, and speaking. The patulous condition of the Eustachian Tubes means that the tube is unable to be closed properly by surrounding muscles.

Patients will experience sound insulation from the nasopharynx without the physician needing to place pressure equalization (PE) tubes through the tympanic membrane.

The device benefits from pneumatic, flexure based valve functionality while being stabilized and held in place with the reliable, well understood stenting technology.

With a domestic market size of $1.5B, product development efforts over the next two years will be followed by animal studies to prove safety and efficacy, human clinical trials to establish acceptability for human use, and finally FDA approval for sale in the US.
