FLEXIBLE VASCULAR OCCLUDING DEVICE
First Claim
1. A tubular-shaped device for positioning within a blood vessel for embolization of an aneurysm, the device including a plurality of strands of helically-wound material in a lattice structure forming a plurality of braiding elements, wherein a width of a braiding element is based on the number of strands of helically-wound material.

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.
