Aneurysm flow diversion is a minimally invasive treatment in which a device known as a neurovascular stent placed in the parent blood vessel of a brain aneurysm may divert blood flow away from the aneurysm. Over time, blood flow into the aneurysm may slow down, eventually ceasing to enter the aneurysm altogether. As the body’s natural healing process works with the flow diversion device, the blood vessel may heal, and the aneurysm may shrink.1-4
Brain Aneurysm Treatment Options
The Pipeline™ Flex embolization device is designed to divert blood flow away from brain aneurysms in certain segments of the internal carotid artery (ICA). The device features a braided cylindrical mesh tube that is implanted across the base or neck of the aneurysm. The device decreases blood flow to the aneurysm, reconstructing the diseased section of the parent vessel. This may result in the aneurysm shrinking in size or resolving over time. Pipeline is the first flow diversion device approved by the FDA.1, 3, 5
Blood flows freely into the aneurysm.
After treatment with Pipeline Flex, blood flow into the aneurysm slows. Over time, blood may no longer flow into the aneurysm.
As the body’s natural healing process works with the Pipeline Flex stent implant, the aneurysm may shrink.3
The Pipeline Flex embolization device has been shown to be effective at treating small, medium, large or giant wide-necked aneurysms, located in specific segments of the internal carotid artery.* 2,4
Potential complications include (but are not limited to):1
Your physician may require medications such as (but not limited to) aspirin and Clopidogrel™† before and after treatment. Persons with known allergy to cobalt/chromium alloy (including major elements of cobalt, chromium, nickel, molybdenum, or tungsten) may suffer an allergic reaction to the Pipeline Flex embolization device.
Check with your doctor for a complete list of potential complications.
Other treatment methods for cerebral or brain aneurysm include no treatment, surgical clipping, endovascular embolization, or observation (non-intervention).6,7
Traditional methods may be insufficient to treat challenging certain aneurysms. Long-term care of these aneurysms can thus be difficult.8
As outlined in PUFs and PREMIER trial results.
Please discuss all risks and warnings with your doctor.
