Technology No. 2023-357
IP Status: Provisional Patent Application Filed


  • Treatment of patulous eustachian tubes.

Technology Overview

Patulous Eustachian Tubes (pET) is a condition where the tube connecting a person’s middle ear to the nasopharynx is unable to be closed properly by surrounding muscles. Researchers at the University of Minnesota have developed an implantable device to provide pressure relief throughout the day to patients with pET. Improving on existing implantable solutions, this device insulates the middle ear from noises in the nasopharynx and requires only simple surgical techniques to implement.

Phase of Development
