Abstract

A method and apparatus for relieving insufflation pressure in a body cavity (18) in excess of a predetermined value are provided. A conduit assembly (24) extends from the body cavity (18) through the surface (61) of a fluid reservoir and has a port (63),positioned beneath the fluid surface (61). The relief pressure is selected by setting the relative positioning of the open end (63) and fluid surface (61). The apparatus avoids insufflation gas leakage problems associated with known insufflation pressure relief devices.
