Abstract

An oesophagoscope (10) comprises a hollow tube (12) of a length at least equal to the length of a patient's oesophagus, the tube having a distal portion (12.1) which is flexible and a proximal portion (12.2) which is inflexible, wherein the flexibility of the distal portion is variable. The flexibility may be varied by means of an elongate member (26) attached to a distal portion of the oesophagoscope and operated (30) from a proximal portion thereof. The distal end of the oesophagoscope may further comprise means adapted to dilate the oesophagus of a patient.
