Abstract:
1. A vascular drilling device for crossing an occluded blood vessel, said device having a main body comprising: an outer tubular member; an inner tubular member interposed within said outer tubular member, said outer and inner tubular members being configured for traversing a patient's vasculature and having a central hole for receiving a guidewire; a distal end cap secured to said outer tubular member and said inner tubular member; a plurality of distal end loops projecting in a distal direction from said distal end cap for fracturing an occlusion; and, a plurality of outer loops projecting radially outwardly from said outer tubular member, whereby said distal end loops and said outer loops fracture an occlusion within a blood vessel when said distal end loops and said outer loops are rotated and pushed through said occluded blood vessel.
