Duradry Sponge DE03 Dural Substitute - Technodry

Mechanism of action: during the surgical procedure, it replaces the dura mater, protecting the nervous system while preventing CSF leakage.

Its action creates a chemotactic environment, attracting macrophages that promote resorption of the collagen matrix.

The non-toxicity characteristic of the manufacturing process allows the survival of fibroblasts carried by the macrophages, which deposit new, native collagen that initiates reconstruction of the injured tissue, in this case permanently replacing the dura mater.

Applications: neurosurgical and/or orthopedic procedures involving injury or loss of the dura mater; dura mater repair after excision or retraction during cranial surgery; brain protection in cases of intraoperative or postoperative swelling; posterior fossa surgery; decompression procedures; spine surgery; and resection of intradural tumors.

Duradry sponge is an organic matrix of polymerized, purified, fibrillar type I collagen, indicated for the repair and correction of dura mater defects. The product can also be used as a covering over sutures placed for dural approximation.
