ABOUT THE THERAPY ANEURYSM FLOW DIVERSION

Refer to technical manual and Instruction for Use (IFU) for complete list of indications, contraindications, warnings and precautions.

ANEURYSM FLOW DIVERSION

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

FLOW DIVERSION

A flow diversion device features a braided cylindrical mesh tube is implanted across the base of the neck of the aneurysm. The device decreases blood flow to the aneurysm, reconstructing the diseased section of the parent vessel. This may result in shrinking in size or resolving over time.

BEFORE FLOW DIVERSION

Blood flows freely into the aneurysm.

FLOW DIVERSION TECHNIQUE

Illustration of the flow diversion technique for treating brain aneurysm

After treatment blood flow into the aneurysm slows. Over time, blood may no longer flow into the aneurysm.

AFTER FLOW DIVERSION

As the body’s natural healing process works, the aneurysm may shrink.3

TRADITIONAL BRAIN ANEURYSM TREATMENT OPTIONS

Other treatment methods for cerebral or brain aneurysm include no treatment, surgical clipping, endovascular embolisation, or observation (non-intervention).6,7 

INVASIVE SURGICAL CLIPPING

  • Surgical procedure requiring an opening of the skull or a craniotomy 
  • Placement of a clip on the neck of the aneurysm to prevent blood flow into the aneurysm

ENDOVASCULAR COIL EMBOLIZATION

  • Minimally invasive approach through a small incision in the leg
  • Placement of embolic coils or liquids into aneurysm to prevent blood flow into aneurysm
