Diagnostic and/or surgical catheter for use in a vessel in the human body through which an opaque liquid is flowing

Abstract

Abstract The catheter comprises a sheath (8) in the general shape of an elongate cylinder provided with through-channels (12, 14, 16, 18) for lighting means, viewing means, means for the supply and removal of an irrigation liquid and/or surgical means, characterised in that the sheath (8) is mounted slidably in an outer cylindrical envelope (20) bearing, in the vicinity of its end and on its outer wall, a first inflatable annular balloon (22) which, when it is pressurised and comes to bear on the wall of the vessel (2) of the body, makes it possible to secure this outer envelope (20) in translation relative to the vessel (2) and to prohibit the circulation of the opaque liquid in the region under observation and/or surgery. <IMAGE>
