An embolic filtering device for use in a bifurcated vessel includes delivery device having a first guide wire and a second guide wire. The second guide wire diverges from the distal-end region of the first guide wire. The filter device also includes a filter support having a first deployment member and a second deployment member. These deployment members can be formed as a first loop and a second loop. A bifurcated filter element is coupled to the filter support. The distal-end region of the first guide wire extends through a first leg of the filter element and the second guide wire extends through a second leg of the filter element. During use, the first leg of the filter element is deployed within a first branch of the bifurcated vessel and the second leg of the filter element is deployed within a second branch of the bifurcated vessel.
What is claimed is: 1. An embolic filtering device, comprising: a first guide wire having a proximal end and a distal end; a second guide wire having a proximal end and a distal end, the second guide wire being coupled to the first guide wire and projecting distally from a distal-end region of the
What is claimed is: 1. An embolic filtering device, comprising: a first guide wire having a proximal end and a distal end; a second guide wire having a proximal end and a distal end, the second guide wire being coupled to the first guide wire and projecting distally from a distal-end region of the first guide wire; and a bifurcated filter assembly having a first filter support and a second filter support, the bifurcated filter assembly being coupled to the first guide wire and including a single filter element attached to both the first and second filter supports, wherein the first and second filter support are positioned substantially longitudinally along the first guide wire. 2. An embolic filtering device, comprising: a first guide wire having a proximal end and a distal end; a second guide wire having a proximal end and a distal end, the second guide wire being coupled to the first guide wire and projecting distally from a distal-end region of the first guide wire; and a bifurcated filter assembly having a first filter support and a second filter support, the bifurcated filter assembly being coupled to the first guide wire and including a single filter element attached to both the first and second filter supports, wherein the first filter support is positioned longitudinally offset from the second filter support along the first guide wire. 3. An embolic filtering device, comprising: a first guide wire having a proximal end and a distal end; a second guide wire having a proximal end and a distal end, the second guide wire being coupled to the first guide wire and projecting distally from a distal-end region of the first guide wire; and a bifurcated filter assembly having a first filter support and a second filter support, the bifurcated filter assembly being coupled to the first guide wire and including a single filter element attached to both the first and second filter supports, wherein the filter element includes a first leg forming a storage area for capturing embolic material extending towards the distal end of the first guide wire and a second leg forming a second storage area for capturing embolic material extending distally towards the distal end of the second guide wire, and the first guide wire extends through the first leg and the second guide wire extends through the second leg. 4. An embolic filtering device, comprising: a first guide wire having a proximal end and a distal end; a second guide wire having a proximal end and a distal end, the second guide wire being coupled to the first guide wire and projecting distally from a distal-end region of the first guide wire; and a bifurcated filter assembly having a first filter support and a second filter support, the bifurcated filter assembly being coupled to the first guide wire and including a single filter element attached to both the first and second filter supports wherein each of the first filter support and the second filter support is a loop of wire which self-expands to a pre-determined configuration and the size of the perimeter of the loop of wires forming the first and second self-expanding filter supports is nonequal. 5. An embolic filtering device, comprising: a first guide wire made from a hollow tubular member having a lumen throughout its length and an aperture within a wall of the tubular member positioned within a distal-end region of the first guide wire; a second guide wire having a proximal end and a distal end, the second guide wire being slidable within the lumen of the first guide wire, the distal end of the second guide wire extending through the aperture in the first guide wire; and a bifurcated filter assembly having a first self-expanding filter support and a second self-expanding filter support, the bifurcated filter assembly being coupled to the first guide wire and including a single filter element attached to both the first and second self-expanding filter supports. 6. The embolic filtering device of claim 5, wherein: the filter element has an opening at a proximal end, the opening of the filter element being coupled to a portion of the first self-expanding filter support and to a portion of the second self-expanding filter support. 7. The embolic filtering device of claim 6, wherein the first guide wire extends through the first leg and the second guide wire extends through the second leg. 8. The embolic filtering device of claim 5, wherein: the filter element includes a first leg extending distally toward the distal end of the first guide wire and a second leg extending distally toward the distal end of the second guide wire. 9. The embolic filtering device of claim 8, wherein: the distal-end region of the first guide wire extends through the first leg of the filter element and the second guide wire extends through the second leg of the filter element. 10. The embolic filtering device of claim 5, wherein the first self-expanding filter is a loop of wire which self-expands to a pre-determined configuration. 11. The embolic filtering device of claim 10, wherein the second self-expanding filter is a loop of wire which self-expands to a pre-determined configuration. 12. The embolic filtering device of claim 11, wherein the loops of wire forming the first and second self-expanding filter supports are positioned substantially longitudinally along the first guide wire. 13. The embolic filtering device of claim 11, wherein the size of the perimeter of the loop of wires forming the first and second self-expanding filter supports are nonequal. 14. The embolic filtering device of claim 5, wherein the first self-expanding filter support is positioned longitudinally offset from the second self-expanding filter support.
