43. A bifurcated catheter system comprising:
-
a catheter, the catheter comprising a first balloon and a second balloon, each balloon having an unexpanded state and an expanded state wherein in the expanded state each balloon has a diameter greater than the diameter in the unexpanded state, a region of each balloon being immediately adjacent one another in both the unexpanded state and the expanded state to define a trunk region; and
a retaining band, the retaining band disposed about the trunk region of the balloons, the retaining band constructed and arranged to limit expansion of the trunk region relative to portions of the balloons adjacent to the trunk region. - View Dependent Claims (44, 45)

46. A bifurcated catheter system comprising:
-
a catheter, the catheter comprising a first balloon and a second balloon, each balloon being expandable from an unexpanded state to an expanded state, wherein in the expanded state each balloon has a diameter greater than the diameter in the unexpanded state, each balloon having a proximal region and a distal region; and
a retaining band, the retaining band disposed about at least a portion of the proximal region of the first balloon and at least a portion of the proximal region of the second balloon, the retaining band constructed and arranged to restrict expansion of the at least a portion of the proximal region of the first balloon and the at least a portion of the proximal region of the second balloon, such that in the expanded state the sum of the diameters of the proximal region of the first balloon and the proximal region of the second balloon is substantially equal to the diameter of the distal region of first balloon. - View Dependent Claims (47)
