(ruralneuropractice.com)
The closed cell design allowed all coils to be placed within the aneurysm and remain outside the flow of the parent artery. (ajnr.org)
2) and fusiform aneurysms without a well-defined neck are more difficult to treat because of the inability to ensure that the coils, once deployed, will remain safely within the aneurysm sac and not obstruct blood flow in the normal parent artery ( 6 ). (ajnr.org)
The advantages of this stent system are that it can be introduced into a standard microcatheter after access is achieved and be partially deployed as much as 70% within the parent artery-and recaptured and redeployed if needed-and the closed cell design improves the ability of the coils to remain within the aneurysm and not protrude into the normal parent artery.
