Device Story

Durepair® Dura Regeneration Matrix is a collagen-based implant designed for surgical repair of dura mater defects. Supplied as a sterile sheet, the device is trimmed by the surgeon to fit the specific defect and applied via suturing or onlay technique. Used in neurosurgical procedures, it acts as a scaffold to facilitate dural regeneration. The device provides a physical barrier to support healing of the dura mater, potentially reducing cerebrospinal fluid leakage and associated complications. It is intended for use by neurosurgeons in a clinical or operating room setting.

Clinical Evidence

Safety and performance demonstrated through biocompatibility studies (ISO 10993), in vitro testing, animal studies, and clinical data.

Technological Characteristics

Collagen-based implant; sterile sheet form; trimmed and sutured or onlayed; biocompatible per ISO 10993.

Indications for Use

Indicated for patients requiring repair of the dura mater.

Regulatory Classification
