A device and method for opening blood vessel blockages, such as chronic total occlusions, is disclosed. The device has a main body and motor unit. The main body has an inner tubular member disposed inside an outer tubular member. The inner tubular member is reinforced with hydrophilic polymer coated wires, which are drawn out into two pairs of loops at the distal end of the device. The motor unit also has an inner tubular member disposed within an outer tubular member. The motor unit is used to create torque to rotate the main body having the pairs of loops. When torque transmitted to main body, the device spins. As the device is advanced through a blood vessel, the rotating loops penetrate and break down the occlusion, and recanalizes the blood vessel. Then device is then exchanged over a guidewire and further therapeutic interventions can be performed to improve blood flow.
A vascular drilling device for crossing an occluded blood vessel, said device having a main body comprising:
A method of traversing a vascular occlusion using a vascular drilling device comprising an outer tubular member, an inner tubular member interposed within outer tubular member, a distal end cap secured to said outer tubular member and said inner tubular member, a plurality of distal end loops projecting form said distal end cap, a plurality of outer loops projecting from said outer tubular member, the method comprising the steps of:
