Implantable intraluminal device and method of using same in treating aneurysms

An assembly for implanting an intraluminal device in a selected site of a blood vessel having an aneurysm, the assembly comprising:

• an intraluminal device, which comprises a braided mesh-like tube of bio-compatible material having an expanded condition in which the tube diameter is larger than the diameter of the blood vessel in which it is to be implanted, and having a length sufficient to be anchored at both ends to said blood vessel and to straddle said aneurysm;
• said braided mesh-like tube being constituted of 24-144 filaments, and being designed to have in its implanted condition a porosity index of 60-75% and windows having an inscribed diameter of 50-320 μm, so as to skew the flow of blood away from the aneurysm sufficiently to decrease the possibility of rupture of said aneurysm;
• and
• a microcatheter for delivering said intraluminal device to said selected site in the blood vessel and for implanting it therein.
