Abstract: A medical stent includes an inner metallic tubular member including a plurality of interconnected struts defining the inner metallic tubular member, and an outer metallic tubular member circumferentially surrounding the inner tubular member. The outer metallic tubular member includes one or more filaments knitted together in a plurality of loops that together form the outer metallic tubular member. The outer metallic tubular member is secured relative to the inner metallic tubular member. The inner tubular member exerts a radially outward force on the outer tubular member in a radially expanded configuration.

Abstract: 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.
