Eustachian catheter, single-use

A Eustachian catheter, single-use is a long, flexible tube designed to drain fluid from the middle ear or temporarily equalize pressure across the eardrum by delivering air through the Eustachian tube. It is inserted through the nose and guided to the Eustachian tube opening, allowing insufflation of air into the middle ear space, and is made of plastic for one-time use only.

As a single-use device, it is intended for one patient and one procedure before disposal. Regulatory oversight focuses on ensuring sterility, material safety, and performance for its intended anatomical pathway and function, with classification determined by jurisdiction based on risk associated with its use in the ear and nasal passages.
