Abstract
An atherectomy device that may reduce the risk of damage to a vessel wall. One rotatable atherectomy burr has a recessed material removal portion lying between less abrasive proximal and distal shoulders. The shoulders can have a straight, rounded or elliptical taper. The shoulders can perform a cam action when the burr is canted is a vessel, as when passing the burr and guide wire through a tortuous, stenosed vessel path. The shoulders act to align the burr with the path through the vessel, presenting the less abrasive shoulders to the vessel wall while presenting the abrasive portion to a stenosis.
