Abstract
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.

68. 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 the distal-end region;
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 filter element attached to the first and second self-expanding filter supports. - View Dependent Claims (69, 70, 71, 72, 73, 74, 75, 76, 77)
