Dura mater graft, bovine

Bovine dura mater grafts are biological materials derived from cow tissue, designed to repair or replace damaged dura mater—the protective outer membrane surrounding the brain and spinal cord. Clinically, they help restore structural integrity during neurosurgery, reduce cerebrospinal fluid leakage, and support healing while gradually resorbing over time.

These grafts are typically classified as biological xenografts and are supplied in sterile, dry forms, often pre-cut into strips or sheets. Regulation varies by jurisdiction, but they are generally subject to stringent standards for tissue sourcing, processing, and sterility to ensure safety and efficacy in neurosurgical applications.
