摘要
An intrasacular aneurysm occlusion device can be a peanut, hourglass, and/or hyperbolic shaped mesh which is inserted and expanded within an aneurysm sac. The proximal lobe of the device reduces blood flow into the sac through the aneurysm neck and the distal lobe of the device contacts the dome of the sac so as to keep the proximal lobe from shifting. The narrow center portion of the peanut, hourglass, or hyperbolic mesh can bend so that the device at least partially conforms to the interior of an irregularly-shaped aneurysm sac.
