Neurovascular Embolization Devices – Overview

Neurovascular embolization devices are medical tools used to treat abnormal blood vessels in the brain and spinal cord by intentionally blocking blood flow to a targeted region. These devices are essential in managing conditions such as intracranial aneurysms, arteriovenous malformations (AVMs), arteriovenous fistulas (AVFs), and certain tumors.

They allow minimally invasive, endovascular treatment performed through small catheters navigating inside blood vessels.

1. Conditions Commonly Treated

• Intracranial aneurysms

Weak or bulging blood vessels in the brain that risk rupture.

• Arteriovenous malformations (AVMs)

Abnormal tangles of blood vessels that disrupt normal blood flow.

• Arteriovenous fistulas (AVFs)

Direct connections between arteries and veins.

• Neurovascular tumors

Such as meningiomas or paragangliomas, where blocking blood supply helps shrink or prepare for surgery.
