Abstract
An atherectomy catheter includes a catheter body having a blade assembly at its distal end. The blade assembly includes first blade and a second blade, where each blade has an opposed cutting edge. At least one of the cutting edges will have a penetrating point formed thereon. Preferably, both edges will have at least one aligned cutting point, more preferably at least two or more aligned cutting points. When the blades are actuated to shear tissue therebetween, the cutting points act to penetrate and capture the material to be sheared.
