The Ferguson-Frazier Suction Tube – Angled 9Fr is a medical suction catheter with a 9 French (Fr) gauge size, indicating a larger diameter than smaller versions like 6Fr, 7Fr, or 8Fr. The "angled" design allows for easier navigation and access to hard-to-reach areas such as the nasal passages, airway, or other body cavities that require suctioning.
