Implantable intraluminal device and method of using same in treating aneurysms
First Claim
1. An intraluminal device implantable in the vicinity of a blood vessel bifurcation, the bifurcation having a source blood vessel, a first branch vessel,and a second branch vessel, an aneurysm being located proximate to the bifurcation, the device comprising:
- a mesh tubular body 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, a contracted condition wherein it is sufficiently flexible so as to be easily manipulatable through a blood vessel to be placed proximate to the bifurcation, and a length sufficient to be anchored to both the source blood vessel and the first branch vessel thereby straddling the opening of the second branch vessel,said mesh tubular body also having a length such that, when placed and anchored to straddle the opening of the second branch vessel, it also straddles said aneurysm, andsaid mesh tubular body having a porosity index of 60-75% when deployed within an appropriately sized blood vessel, so as to skew the flow of blood away from the aneurysm sufficiently to decrease the possibility of rupture of said aneurysm but not to unduly reduce the blood flow to said second branch vessel to a degree likely to cause significant damage to tissues supplied with blood by such second branch vessel.

Abstract
A method and apparatus for reducing blood flow to an aneurysm proximate to a bifurcation having a source blood vessel a first branch vessel and a second branch vessel, the method comprising: providing a first mesh-like tube of bio-compatible material, the first mesh-like tube exhibiting a porosity index pre-selected to skew blood flow about the bifurcation away from the aneurysm; inserting the first mesh-like tube into the source blood vessel and the first branch vessel; and securing the first mesh-like tube to at least one of the source blood vessel and the first branch vessel, whereby blood flowing from the source blood vessel flows without undue impedance to the first branch vessel and the second branch vessel while being skewed away from the aneurysm.

21. An intraluminal device implantable in the vicinity of a blood vessel bifurcation, the bifurcation having a source blood vessel, a first branch vessel, and a second branch vessel, an aneurysm being located proximate to the bifurcation, the device comprising:
-
a tubular body formed by braiding a plurality of filaments, and 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, a contracted condition wherein it is sufficiently flexible so as to be easily manipulatable through a blood vessel to be placed proximate to the bifurcation, and a length sufficient to be anchored to both the source blood vessel and the first branch vessel thereby straddling the opening of the second branch vessel, said tubular body also having a length such that, when placed and anchored to straddle the opening of the second branch vessel, it also straddles said aneurysm, and said tubular body having a porosity index of 60-75% when deployed within an appropriately sized blood vessel, so as to skew the flow of blood away from the aneurysm sufficiently to decrease the possibility of rupture of said aneurysm but not to unduly reduce the blood flow to said second branch vessel to a degree likely to cause significant damage to tissues supplied with blood by such second branch vessel. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
