The invention relates to a catheter around which a separate, flexible sheath is arranged. During insertion of the catheter, the catheter with sheath is carried via the oral cavity and the oesophagus to a position at a distance from for instance a wound in the stomach. The sheath is then withdrawn. This ensures that the catheter itself remains sterile since it does not come into contact with the oral cavity which normally contains a large number of bacteria. <IMAGE> |
