Apparatus for intubation of the cervix, especially for the implantation of a fertilised ovum, comprises a hub connected to a flexible catheter and a sheath surrounding said catheter, said sheath being more rigid than said catheter and having an enlarged grip portion adapted to be gripped by an operator at its proximal end, said sheath being slidable from a first position in which the distal end of said catheter terminates approximately level with the distal end of said sheath to a second position in which said grip portion is abutting said hub and said catheter projects beyond the distal end of said sheath by a distance not less than the intended depth of intubation into the cervical canal. |
