Minimally Invasive Intravascular Treatment Device

A mounting arrangement, for mounting cutting blades on a device for treating a target area of a vessel wall of a vessel within a human or animal body, comprising:

• at least two spaced-part cutting blades;
• and
• a linkage incorporating a pivot point and interconnecting the cutting blades so as to allow relative rotation of the blades about the pivot point.

A device for treating a target area of a vessel wall of a vessel within a human or animal body, the device comprising:

• an expandable portion for radially expanding the device from a contracted configuration allowing travel within the vessel to the target area to an expanded configuration allowing treatment of the target area;
• at least two spaced-part cutting blades moveable by the expandable portion from a retracted position to a working position, the blades interconnected by a linkage incorporating a pivot point the linkage allowing relative rotation of the blades about the pivot point.

A mounting arrangement, for mounting cutting blades on a device for treating a target area of a vessel wall of a vessel within a human or animal body, comprising at least two spaced-part cutting blades each having a blade body, the blades being interconnected by a flexible or pivot linker which is insertable into each blade body.
