Once the balloon-tipped catheter is inserted, saline is injected into the balloon, causing it to expand and dilate the cervix. Laminaria is a type of seaweed native to Japan that forms a thick, sticky gel when wet. The dried stems of the seaweed are formed into “tents” that will swell up gradually. A layer of this substance is placed just inside the cervix, around the neck of the uterus to promote cervical dilation. Although laminaria has been used both before dilation and curettage and to stimulate labor, the safety of its use during pregnancy has not been proven at this time.
