VESSEL SCORING DEVICE

A medical device includes a catheter shaft including a distal region and an inflatable balloon that is secured to the distal region of the catheter shaft. The inflatable balloon has an outer surface and defines a centerline when inflated. A blade extends over and is secured to the outer surface, the blade having a cutting edge extending from a distal end of the blade to a proximal end of the blade, when the inflatable balloon is inflated, the cutting edge extends to a maximum distance measured relative to the centerline of the inflatable balloon at the distal end of the blade and a minimum distance measured relative to the centerline of the inflatable balloon of the medical device at the proximal end of the blade.
