A device suitable for removing material from a living being is provided, featuring an infusate pump (38), and an aspiration pump (40), both powered by a motor (26). The aspiration pump and infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. |
