Intended Use

Durasis® Dural Substitute is intended for use as a dura substitute for repairing dura mater. The device is intended for one-time use.

Device Story

Durasis® Dural Substitute is a surgical graft material derived from porcine small intestinal submucosa. It is used by neurosurgeons during surgical procedures to repair or replace the dura mater. The device is supplied in various sizes up to 140 cm² and is intended for single-use. By providing a scaffold for tissue repair, the graft assists in the closure of the dura mater, potentially reducing the risk of cerebrospinal fluid leakage and supporting natural healing processes. It is provided sterile in double-pouch packaging.

Clinical Evidence

The device underwent in vitro, in vivo, and clinical evaluations to assess biocompatibility, mechanical properties, and performance characteristics. Results demonstrated that the material met established criteria for dura mater replacement, supporting safety and substantial equivalence to predicate devices.

Technological Characteristics

Material: Porcine small intestinal submucosa. Form factor: Sterile graft patch, various sizes up to 140 cm². Packaging: Sterile, sealed double pouches. Intended for single-use.

Indications for Use

Indicated for use as a dura substitute for the repair of dura mater in patients requiring such surgical intervention.

Regulatory Classification
