Abstract

A novel intravascular occlusion material removal device (10) for removing vascular occlusion material in a vascular lumen comprises a prime mover (12) and an expandable material removal element (16) insertable intravascularly into the vascular lu-men. A hollow drive shaft (26) operatively connects the prime mover (12) to the expandable material removal element (16) for ro-tating the expandable material removal element (16) intravascularly. A
guidewire (42) is insertable through the distal end of the expandable material removal element (16) and the hollow drive shaft (26), and is shiftable within the drive shaft (26) and the ex-pandable material removal element (16). The expandable material removal element (16) is expandable responsive to shifting of the guidewire (42). A material removal element movement control mechanism (52) is operatively connected to the guidewire (42) for positively incrementally shifting the guidewire (42), and a guidewire lock mechanism is operatively connected between the guidewire and the material removal element movement control mechanism for fixing the guidewire with respet to the material removal element movement control mechanism.
