Patent ID: 8748508

Claim:
A membrane composition for securement to a patient's bone or soft tissue to reduce the formation of tissue adhesions following a surgical procedure comprising a first component and a second component, the first component comprising a hydrogel including poly(vinyl alcohol) crosslinked to a second polymer, a ratio of the poly(vinyl alcohol) to the second polymer ranges from about 75:1 to about 200:1, the second component comprising a textile component, wherein 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 flexibility of less than thirty millimeters (30 mm) bend length, wherein the textile component is encapsulated by the first component, and the first component is configured to be in contact with the patient's bone or soft tissue when secured thereto.
