Abstract
A system is provided having a catheter, a torque member extending longitudinally through a lumen of the catheter, a removal mechanism secured to a distal end of the torque member, and a guidewire having a guide section that extends through a lumen of the removal mechanism. The guide section defines a curved profile that is diametrically larger than the dimension of the removal mechanism. The guide section of the guidewire is adapted to be positioned inside a passageway of the occluding material, and provides a curved path along which the removal mechanism can be advanced inside the passageway of the occluding material to separate and remove occluding material.
