Until now, certain kinds of aneurysm could not be easily treated either with an open operation or an endovascular procedure.  The development of intracranial stents has changed all that, however.

An intracranial stent is a tiny tube that can act like a miniature scaffolding to hold open a blood vessel during aneurysm repair with microcoils, allowing coil placement even in difficult-to-reach parts of the brain.
