Method for preparing dural graft and the Graft

摘要

Provides a dural Graft that has improved stiffness characteristics in comparison with conventional dural substitutes. The dural Graft can be composed of a Collagen material having a stiffness between about 0.1 lire per inch (lb / in) and 0.25 pounds per inch.With regard to the Collagen material that composes the substitutes of Conventional dural grafts, the stiffness of the Collagen material decreased the dural Graft can give the Graft a malleability relatively improved or increased.As a result of the increased malleability, the dural Graft Can Adapt sufficiently 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 flexibility or Elasticity of the dural Graft relatively improved or increased.The increased flexibility of the dural Graft Graft decreases the tear when it comes or manipulates a grafting procedure.
