Procedures for vascular occlusion
First Claim
1. A method of reducing blood flow within an aneurysm comprising:
- injecting a contrast agent into a blood vessel comprising an aneurysm;
deploying an occlusion device from a delivery device in the blood vessel next to the aneurysm;
producing an image of the aneurysm including the contrast agent;
confirming that the contrast agent forms a shape after deploying the occlusion device; and
while the contrast agent has formed the shape, withdrawing the delivery device from the blood vessel.

Abstract
A method of reducing blood flow within an aneurysm includes: injecting a contrast agent into a blood vessel including an aneurysm; expanding a stent, from a delivery device, across the aneurysm; and confirming that a stagnated area forms in the aneurysm. The stagnated area can form a crescent shape, a mushroom shape, a hemispherical shape, and/or a flat side. Upon confirming that the stagnated area forms in the aneurysm, the delivery device can be withdrawn from the blood vessel. The stagnated area can include the contrast agent. If the stagnated area does not form in the aneurysm, a second occluding device may be deployed. After withdrawing the delivery device, substantially all of the aneurysm progressively thromboses.

10. A method of implanting a stent at an aneurysm comprising:
-
providing an elongate body comprising a proximal portion, a distal portion, and a lumen extending between the proximal portion and the distal portion; advancing the elongate body into a patient until the distal portion is adjacent to the aneurysm; delivering a stent across the aneurysm from within the lumen at the distal portion of the elongate body, wherein delivering the stent comprises expanding the stent from a compressed configuration to an expanded configuration with a first location distal to the aneurysm and a second location proximal to the aneurysm; observing stagnation within the aneurysm caused by delivering the stent across the aneurysm; and withdrawing the elongate body from the patient with the expanded stent remaining across the aneurysm once the observed stagnation produces a persistent shape in the aneurysm. - View Dependent Claims (11, 12, 13, 14)

15. A method of reducing blood flow within an aneurysm comprising:
-
injecting a contrast agent into a blood vessel comprising an aneurysm, at least a portion of the contrast agent flowing into the aneurysm; deploying an occlusion device from a delivery device in the blood vessel next to the aneurysm; stagnating the portion of the contrast agent in the aneurysm; producing an image of the aneurysm including the portion of the contrast agent; observing a shape formed by the portion of the contrast agent in the aneurysm after deploying the occlusion device; and withdrawing the delivery device from the blood vessel after observing the shape. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
