Abstract
A system for insufflating a vessel in a human or animal body, such as the rectum comprises a first pressure sensor located adjacent a leading end of an endoscope for monitoring pressure in the rectum. A second pressure sensor located on a carrier element which is urgeable through the endoscope into the colon monitors pressure therein. Insufflating air which may leak into the abdominal cavity is exhausted therefrom by a needle. A third pressure sensor monitors pressure in the abdominal cavity. A microcontroller controls the supply of insufflating air to the rectum for maintaining pressure in the rectum at a first predefined pressure, for preventing pressure in the colon exceeding a second predefined pressure, and for controlling a vacuum pump for drawing insufflating air from the abdominal cavity to prevent pressure therein exceeding a third predefined pressure.
