Intracerebral cannula, nonimplantable, reusable

An intracerebral cannula is a rigid, nonimplantable tube designed for temporary surgical access to the brain, often used to drain cerebrospinal fluid (CSF), deliver therapeutic agents, or guide instruments for diagnostic or treatment procedures. These devices are typically inserted through the skull to reach targeted brain regions, such as the ventricles, and may include features like a stylet or trocar for precision insertion.

These reusable cannulas must be sterilized before each use and are regulated under medical device standards that account for their invasive nature and direct contact with the brain. They are supplied sterile or as clean, reusable instruments, depending on the manufacturer’s specifications and local regulatory requirements. Classification varies by jurisdiction and intended use, but they are generally subject to stricter controls due to their surgical application.
