Abstract
An intravascular catheter device for modifying tissue located within a blood vessel and methods of using the same are provided. An expandable portion is secured to a distal end of a flexible catheter tube and is operable between a first position and a second position where the expandable portion is enlarged. An incising element extends lengthwise along an outer surface of the expandable portion and is configured to create axially extending slits in the tissue when the expandable portion is placed in the second position and moved axially through the blood vessel. An abrasive is provided at the outer surface of the expandable portion for abrading the tissue when the expandable portion is placed in the second position and move axially through the blood vessel.
