Cervical canal (i.e., uterine cervix) dilators consisting of an expansible plug (i.e., a tent) of dried Laminaria (a genus of seaweeds); they are usually available as sterilized devices that have a strong thread attached for anchoring and easy removal. These tents gradually swell to several times their original diameter by the absorption of moisture from the cervix in a period of several hours (typically 12 to 14), producing a gradual cervical dilatation. Laminaria tent cervical dilators are used to perform intrauterine obstetric maneuvers, especially to perform midterm abortions.
