Abstract
Apparatus for collecting emboli flowing in a lumen. A motor has a longitudinal bore, a friction area within the longitudinal bore, and a guide wire disposed within the longitudinal bore. The guide wire and friction area of the motor are sized and adapted to contact each other and impart friction between the friction area and the guide wire to permit the motor to rotate around the guide wire. A thrombus collecting gutter is attached to the motor. Paddles are attached to motor and are adapted to initiate a spiral blood flow when the motor rotates. The spiral blood flow causes thrombii in the blood to be deflected towards the internal wall of the lumen and be trapped in a thrombus collecting gutter which is positioned on the motor downstream of the paddles.
