The ornamental design for an expandableexoskeleton for a balloon catheter, as shown and described.
FIG. 1 is a perspective view of an expandable exoskeleton for a balloon catheter showing our new design, with the expandable exoskeleton in an unexpanded state, the expandable exoskeleton capable of placement over a balloon of a balloon catheter;
FIG. 2 is a first side elevational view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 3 is a second side elevational view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 4 is a third side elevational view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 5 is a fourth side elevational view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 6 is a distal end view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 7 is a proximal end view of the expandable exoskeleton for a balloon catheter in the unexpanded state;
FIG. 8 is first side elevational view showing our new design, with the expandable exoskeleton for a balloon catheter in an expanded state;
FIG. 9 is a second side elevational view of the expandable exoskeleton for a balloon catheter in the expanded state;
FIG. 10 is a third side elevational view of the expandable exoskeleton for a balloon catheter in the expanded state;
FIG. 11 is a fourth side elevational view of the expandable exoskeleton for a balloon catheter in the expanded state;
FIG. 12 is a distal end view of the expandable exoskeleton for a balloon catheter in the expanded state; and,
