A flexible tube designed for combined saline infusion sonohysterography (SIS) and biopsy functionality providing the physician with increased visibility offered by a sonohysterography during a diagnostic image ultrasound and the ability to take a biopsy of endometrial tissue during the same gynaecological procedure. It is introduced via the vagina and allows the uterus to be filled with saline which is retained with an acorn-tipped stopper placed against the cervical opening; a biopsy can be taken if indicated. This is a single-use device.
