A suction catheter having a spoon-shaped distal end designed to assist manual removal of large airway occluding particles from the oropharynx and mouth opening to near the epiglottis of a patient by an emergency caregiver. The tip of the spoon-shaped distal end defines an ovular orifice of sufficient size to remove both viscous and non-viscous matter including particulate matter from the airway of the patient. The catheter includes an elongated hollow member for conveying the unwanted viscous and non-viscous matter and is flexible about a portion displaced from the spoon-like distal end and includes a flexible stylet member therein to permit bending of the catheter and causing it to retain its bent shape with the proximal end thereof away from the patient to allow the caregiver more freedom to provide care to the patient. An opening is provided in the catheter and communicates with the internal airway for use in controlling the amount of suction provided by the connection of the proximal end of the catheter to a vacuum source.
