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: An organ can be cooled to minimize ischemic tissue damage from a vascular occlusion by a thrombus or dissection. A catheter including a thermal member can be used to introduce cold fluid downstream from an arterial occlusion to cool tissue affected by the occlusion. This is particularly useful to minimize neurologic damage from a thrombotic stroke.

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

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 stagnated by a desired amount. The image may be two-dimensional or three-dimensional. Observing that the aneurysm has been stagnated may include determining a degree of stagnation, 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 stagnation, identification of a shape indicative of stasis such as a flat surface, an approximate hemisphere, a mushroom, or a crescent.
