A cutting element (4) is coupled to the rotatable shaft (20), the cutting element (4) having a cutting edge (22), the cutting element (4) and rotatable shaft (20) being longitudinally moveable within the tubular body (8) between a stored position in which the cutting element (4) is parallel a longitudinal axis of the tubular body (8) and a cutting position in which the cutting element (4) is deflected between the proximal and distal ends of the tubular body (8) to extend beyond an outer diameter of the tubular body (8). The cutting element (4) is configured to cut material from the wall of a vessel at a treatment site as the catheter (2A) is pushed distally through the treatment site. The catheter (2A) includes a collection chamber (12) positioned proximally of the cutting window.
