Detailed Description

A multi-center (up to 4 sites) clinical case series of 110 patients treated with Collagen Dura Regeneration Membrane - Repair (DMR) for a dural defect in the dura mater will be evaluated prospectively. The primary endpoint is the rate of adverse events related to the Subject Device requiring surgical intervention. Patients will have a follow-up evaluation post-operatively in line with standard or care of the study site, and 8 months after the initial surgery. No original patient records or personal identifying information will be disclosed to CMI.
