An illustration of nuerovasculature with aneurysms created for eV3. The client’s microcatheter balloons are featured adjacent to the aneurysms so they can assist in the coiling. The inflated balloons prevent the coils deployed into the aneurysms from escaping into the blood vessels during the coiling procedure by blocking them until a secure coil knot has been formed.
An arteriovenous malformation is a tangle of faulty arteries and veins that can rupture within the brain. AVM repair helps prevent further bleeding in the brain. Doctors use several methods to repair AVMs. These methods include: Injecting a substance into the blood vessels of the AVM to block blood flow, surgery to remove the AVM, and using radiation to shrink the blood vessels of the AVM. – National Institute of Health
We were asked to illustrate the detachable tip of eV3’s Apollo Onyx Delivery Micro Catheter. It allows the delivery of glue that blocks off the AVM while mitigating the risk of catheter entrapment. The catheter can inject more glue, over longer periods, while safeguarding the neurovasculature during it’s retrieval.
Healthcare providers use endovascular coiling, also called endovascular embolization, to block blood flow into an aneurysm. A catheter, a long thin tube, is inserted into a groin artery. The catheter is advanced into the affected brain artery where the coil is deployed. X-rays help guide the catheter into the artery. The coils are made of soft platinum metal, and are shaped like a spring. These coils are very small and thin, ranging in size from about twice the width of a human hair to less than one hair’s width. – John Hopkins Health Library
This series of illustrations for eV3 shows the steps involved when the aneurysm has a wide neck. To prevent the coils from spilling out into the neighboring blood vessel, an inflated micro balloon blocks the neck opening while the coiled knot is created.
