osmed Hemisphere Expander - osmed self-inflating tissue expanders are made of a specially developed hydrogel (methylmethacrylate-n-vinylpyrrolidone-co-polymer) using the osmotic principle to expand physiological tissue space due to the absorption of body fluid from the surrounding tissues. The osmed Hemisphere Expanders are used for expansion of the connecting tissue sack at congenital anophthalmia and microphthalmia.
