Procedures for vascular occlusion
First Claim
1. A method of reducing blood flow within an aneurysm of a blood vessel, the method comprising:
- expanding a stent, from a delivery device, across the aneurysm, such that a stagnated area forms in the aneurysm;
injecting a contrast agent into the blood vessel;
confirming that the stagnated area forms one or more predetermined shapes indicating the stagnated area occupies less than 70% of a body of the aneurysm; and
while the stagnated area has formed the one or more predetermined shapes, 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 Upon confirming that the stagnated area forms in the aneurysm, the delivery device can be withdrawn from the blood vessel.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 reducing blood flow within an aneurysm of a blood vessel, the method comprising:
-
expanding a stent, from a delivery device, across the aneurysm, whereby a stagnated area forms one or more predetermined shapes indicating the stagnated area occupies less than 70% of the volume of the aneurysm; injecting a contrast agent into the blood vessel, at least a portion of the contrast agent flowing into the aneurysm; and withdrawing the delivery device from the blood vessel upon confirming that the stagnated area forms the one or more predetermined shapes. - View Dependent Claims (11, 12, 13, 14, 15, 16)

-
expanding a stent, from a delivery device, across the aneurysm; injecting a contrast agent into the blood vessel; and withdrawing the delivery device from the blood vessel upon confirming that the aneurysm has formed a stagnated area comprising one or more predetermined shapes indicating the stagnated area fills less than 70% of the volume of the aneurysm; wherein, after withdrawing the delivery device, substantially all of the aneurysm progressively thromboses. - View Dependent Claims (18, 19, 20)
