A balloon catheter for insertion in a vessel includes a catheter shaft (24) and an inflatable balloon (12) attached to the catheter shaft. Markings (30,32,39) along a longitudinal axis of the catheter are provided in an interior of the balloon, such as for measuring a distance within the vessel. A first distance separating a first marking from a second adjacent marking may be different from a second distance separating the second marking from a third adjacent marking. The markings may also be used for ensuring the proper positioning of the balloon and, in particular, the working surface thereof, relative to a treatment area. |
