The ACMI 240036 Shea Parasol Vent Tube is a specialized middle ear ventilation tube designed for use in otologic surgery, particularly for patients requiring long-term middle ear aeration. Developed in collaboration with Dr. John J. Shea, this tube features a unique "parasol" design that helps maintain placement and minimize migration within the tympanic membrane. It is constructed from medical-grade silicone, ensuring biocompatibility and minimizing tissue reaction. The tube has an inner diameter of 1.02 mm and is equipped with a tab for secure positioning.
