Endoscopy device

An endoscopy device for facilitating the use of an endoscope, comprising:

• at least one airway tube and a mask carried at one end of the at least one airway tube,
• the mask having a distal end and a proximal end and a peripheral formation capable of conforming to, and of fitting within, the actual and potential space behind the larynx of the patient so as to form a seal around the circumference of the laryngeal inlet,
• the peripheral formation surrounding a hollow interior space or lumen of the mask and the at least one airway tube opening into the lumen of the mask,
• the peripheral formation establishing separation between a laryngeal chamber side and a pharyngeal side,
• the device further comprising a conduit adapted for passage of an endoscope into the oesophagus of a patient when the mask is in place, the conduit including a distal end for cooperation with the oesophageal sphincter of the patient, the conduit having a laryngeal side, a pharyngeal side, and with respect thereto, a right side and a left side, and an outlet wherein at the outlet the width between the left side and the right side is smaller than the width of the conduit.
