A uterine manipulator device 10 for injecting a visualisation fluid into the uterine cavity of a female via the cervix. The device 10 comprises an elongate body 12, a tanaculum for gripping the cervix and an inflatable bladder 20 for forming a fluid-resistant seal with the cervix. The elongate body has a conduit 35 along which visualisation fluid can be conveyed to the uterus and a conduit 37 for air, having an outlet opening 44, which is connectable to a pressurized air supply. The bladder is mounted on the elongate body over the outlet opening 44, surrounding the elongate body and sealed to the elongate body at opposite ends of the bladder. The bladder includes an outer sealing element 52 which, upon inflation, forms a fluid-tight seal with the cervix, and an inner sleeve 54 which fits over the opening 44 preventing a return flow of air, yet allowing pressurized air into the bladder for inflating it.
