摘要:
#$%^&*AU2012201918B220131107.pdf#####ABSTRACT A dural graft is provided having improved stiffness characteristics relative to conventional dural substitutes. The dural graft can be formed from a collagen material having a stiffness between about 1.75 N/m (0.01 pounds per inch (lb./in.)) and 43.75 N/m (0.25 lb./in.) Relative to the collagen material forming conventional dural graft substitutes, the decreased stiffness of the collagen material of the present dural graft can provide the graft with a relatively improved or increased pliability. As a result of the increased pliability, the dural graft can sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The reduced stiffness of the collagen material can also provide for a relatively improved or increased flexibility or elasticity of the dural graft. The increased flexibility of the dural graft minimizes tearing of the graft when handled or manipulated during an implantation procedure. 03/iO/13,M\Graham\Care\Speci & Amndmts\19850 Speci.Doex,131/4 10 16 FIG. 1 18 10 16 -FIG. 2 12 14 16 FIG. 3
