An apparatus for treating a treatment area along an inner wall of a vessel using a catheter having a balloon including a working surface, the working surface being a surface along a largest diameter portion of the balloon adapted to contact the treatment area within the vessel when the balloon is inflated, comprising:
- a guidewire for guiding the balloon to the treatment area, said guidewire including one or more radiopaque markings corresponding to a length of the working surface of the balloon, the correspondence being a correspondence in size.
An apparatus for treating a treatment area along an inner wall of a vessel, comprising:
- a catheter including a distal end supporting a balloon having a working surface, the working surface being a surface along a largest diameter portion of the balloon adapted to contact the treatment area when the balloon is inflated and a proximal end;
- and
- a guidewire for guiding the balloon to the treatment area, said guidewire including one or more radiopaque markings adapted for corresponding to a length of the working surface of the balloon when positioned at the treatment area.
An apparatus for treating a treatment area in the vasculature using a catheter having a balloon including a barrel section having a length for engaging the treatment area, comprising:
- a guidewire for guiding the balloon to the treatment area, said guidewire including one or more radiopaque markings corresponding to the length of the barrel section of the balloon, the correspondence being a correspondence in size.
