Abstract
A method of forming and the resulting membrane composition for securement to a patient's bone or tissue to reduce the formation of tissue adhesions following a surgical procedure comprises a first component and a second component. The first component comprises a hydrogel including at least one crosslinked polymer. The second component comprises a textile component. The composition has a thickness between about two tenths of a millimeter (0.2 mm) to about six tenths of a millimeter (0.6 mm), a suture retention strength between about one Newton (1 N) to about thirteen Newtons (13 N), a static coefficient of friction between about one hundredth (0.01) and about one-half (0.5), a kinetic coefficient of friction between about one hundredth (0.01) and about one-half (0.5) and a flexibility of less than thirty millimeters (30 mm) bend length. A method of reducing the occurrence of tissue adhesions following surgery comprises applying the membrane composition to a surgical site.
