Itard Eustachian Catheter Fig.4

Clinical Application

Designed for use by otolaryngologists and ENT surgical teams, this instrument facilitates controlled cannulation of the Eustachian tube via the nasopharyngeal orifice. Typical clinical uses include diagnostic assessment of tubal patency, insufflation/ventilation of the middle ear, and controlled delivery of air or fluid during middle‑ear procedures. It is intended for use in clinic, ambulatory surgery center, or hospital settings where reusable otologic instrumentation is required.

Design & Configuration

The figure‑4 curvature provides a predictable bend profile that aligns the distal lumen with the Eustachian tube opening when introduced transnasally, improving access and reducing the need for excessive instrument manipulation. A smooth, atraumatic rounded distal tip reduces mucosal trauma during placement while the rigid shaft transmits controlled hand movements for precise cannulation. The hollow lumen allows connection to manual insufflation or irrigation devices to permit controlled delivery of air or fluid into the middle ear space.
