Abstract
An implant that may maintain position with a Eustachian tube of a patient, the implant includes an engagement body, an anchoring assembly, and a pressure balance assembly. The engagement body includes an exterior surface dimensioned to bear radially outward against the Eustachian tube. The anchoring assembly may lock the implant in the Eustachian tube. The pressure balance assembly includes a vented pathway that may transition between an occluded state and a vented state. The vented pathway may provide fluid communication between the proximal end and the distal end of the implant in the ventilated state while inhibiting fluid communication between the proximal end and the distal end of the implant in the occluded state.
