Osmotic dilators prior to expansion. Dilapan-S (left). Laminaria (right)
Osmotic dilators are medical implements used to dilate the uterine cervix by swelling as they absorb fluid from surrounding tissue.[1] They may be composed of natural or synthetic materials. A laminaria stick or tent is a thin rod made of the stems of dried Laminaria, a genus of kelp. Laminaria sticks can be generated from Laminaria japonica[2] and Laminaria digitata.[3] Synthetic osmotic dilators are commonly referred to by their brand names, such as Dilapan.[4] Dilapan-S are composed of polyacrylonitrile, a plastic polymer.[4] The hygroscopic nature of the polymer causes the dilator to absorb fluid and expand.
