This invention relates to a surgical smoke evacuation system for use in removing gases and smoke created in surgical procedures form within an insufflated surgical cavity. Such a system comprises a discharge assembly adapted to form a gases path, and having an end which in use is located within said surgical cavity so that gases and/or surgical smoke inside said cavity can pass out of said cavity and through said discharge assembly along said gases path, a flexible discharge limb having an operational site end and an outlet end, and a self-supporting wall defining a gases flow passage between said operational site end and said outlet end, in use said open operational site end sealingly connected to said discharge assembly so that said gases and/or surgical smoke can pass out of said discharge assembly and into said discharge limb, a filter connected in use to the outlet end of the discharge limb, at least part of said wall of the discharge limb formed from a breathable material, said breathable material allowing the passage of water vapour through the wall of the discharge limb without allowing the passage of liquid water or surgical smoke or other gases.
