Abstract
A method of reducing blood flow within an aneurysm includes: injecting a contrast agent into a blood vessel including an aneurysm; deploying an occlusion device across the aneurysm; producing an image of the aneurysm including the contrast agent; and withdrawing the delivery device from the vessel after observing that the aneurysm has been stagnated by a desired amount. The image may be two-dimensional or three-dimensional. Observing that the aneurysm has been stagnated may include determining a degree of stagnation, for example by comparing an area or volume of the contrast agent in a first image and a second image. The desired amount may be a certain degree of stagnation, identification of a shape indicative of stasis such as a flat surface, an approximate hemisphere, a mushroom, or a crescent. If the occlusion device does not achieve the desired amount, a second occluding device may be deployed.
