An intracranial neurovascular stent is a tubular device placed in the blood vessel of the intracranial cavity to treat a vascular abnormality. It differs from other stents in that it is intended for intracranial use.
The FDA has not linked product code NJE to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:
The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
