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 Upon confirming that the stagnated area forms in the aneurysm, the delivery device can be withdrawn from the blood vessel.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.

Abstract: A vascular occluding device for modifying blood flow in a vessel, while maintaining blood flow to the surrounding tissue. The occluding device includes a flexible, easily compressible and bendable occluding device that is particularly suited for treating aneurysms in the brain. The neurovascular occluding device can be deployed using a micro-catheter. The occluding device can be formed by braiding wires in a helical fashion and can have varying lattice densities along the length of the occluding device. The occluding device could also have different lattice densities for surfaces on the same radial plane.

Abstract: Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

Abstract: A vascular remodeling device is provided. The device has an anchor portion, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. The device also includes a distal portion sized for deployment in a blood vessel. The distal portion is radially expandable from a collapsed state to an expanded state and has a distal face that is sufficiently occlusive in the distal-to-proximal direction to perform a therapeutic blocking function in an aneurysm neck. The device also has an intermediate portion that interconnects a distal end of the anchor portion and a proximal end of the distal portion. In some embodiments, the anchor portion and/or distal portion has a plurality of interconnected struts.
