Procedures for vascular occlusion

A method of reducing blood flow within an aneurysm, the method comprising:

• injecting a contrast agent into a blood vessel comprising an aneurysm;
• deploying a stent from a delivery device across the aneurysm, whereby the aneurysm thromboses by less than 70% of a volume of the aneurysm to form a shape;
• producing an image of the aneurysm including the contrast agent;
• observing the shape formed by the contrast agent after deploying the stent;
• and
• withdrawing the delivery device from the vessel after observing the shape.

A method of implanting a stent at an aneurysm, the method 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 the 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 partial thrombosis of between about 30% and about 70% of 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 partial thrombosis produces a persistent shape indicative of thrombosis in the aneurysm.

A method of reducing blood flow within an aneurysm, the method 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 a stent from a delivery device across the aneurysm, whereby between about 30% and about 70% of the volume in the aneurysm thromboses;
• producing an image of the aneurysm including the portion of the volume that has thrombosed;
• observing a shape formed by the portion of the volume that has thrombosed in the aneurysm after deploying the stent;
• and
• withdrawing the delivery device from the vessel after observing the shape.
