Abstract: A system and method for deploying an occluding device that can be used to remodel an aneurysm within the vessel by, for example, neck reconstruction or balloon remodeling. The system comprises an introducer sheath and an assembly for carrying the occluding device. The assembly includes an elongated flexible member having an occluding device retaining member for receiving a first end of the occluding device, a proximally positioned retaining member for engaging a second end of the occluding device and a support surrounding a portion of the elongated flexible member over which the occluding device can be positioned.

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: A vascular remodeling device has a plurality of sections, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. Each section has a plurality of interconnected struts that define a waist, a proximal face, and a distal face. Each face comprises (i) a plurality of distal strut portions extending proximally from a distal side of the face, (ii) a plurality of proximal strut portions extending distally from a proximal side of the face, and (iii) a plurality of sub-struts, wherein, from each proximal strut portion, two of the sub-struts each extend to a different one of the distal strut portions.

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.

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 obstructed by a desired amount. The image may be two-dimensional or three-dimensional. Observing that the aneurysm has been obstructed may include determining a degree of obstruction, 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 obstruction, 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.
