ORIENTED BIOPOLYMERIC MEMBRANE FOR MENINGEAL TISSUE REPAIR

摘要

A cell occlusion sheet membrane adapted for repairing a damaged meningeal tissue. The sheet membrane contains a layer of cross-linked, oriented biopolymeric fibers that has a thickness of 0.1 mm to 3.0 mm, a density of 0.1 g/cm<3> to 1.2 g/cm<3>, a hydrothermal shrinkage temperature of 45°C to 80°C, a suture pullout strength of 0.1 kg to 5 kg, a tensile strength of 10 kg/cm<2> to 150 kg/cm<2>, and permeability to molecules having molecular weights of 200 to 300,000 daltons. Also disclosed is a method for making the membrane.
