About

The objective of the proposed investigation is to assess the safety and effectiveness of the Merlin's DiVeRt system for the treatment of intracranial lesions.

Merlin is a manufacturer of Flow- Diverters (FD) for Neurovascular applications. The technology is based on a microporous polymer membrane which is delivered to the site of lesion treatment using a metal stent scaffold. The first device in its FD family is the XCalibur Aneurysm Occlusion Device (AOD) system, which is delivered on a rapid-exchange balloon catheter which goes in a 6-Fr guide-catheter. The AOD is CE-marked and has been involved in the treatment of over 70 clinical lesion/aneurysm cases. The same technology is now being made available in a self-expandable stent platform delivered on a 0.028" microcatheter. Merlin has performed the required in-silico, in-vitro and in-vivo tests to be confident of the device performance and now intends to proceed to the human clinical-trials. DiVeRt (Interventional) is a non CE mark device. The device is under clinical trial phase. The competent authority submission for the study has been completed in Spain, Turkey and Hungary.
