Patent Application - MECHANICAL PUMP FOR REMOVAL OF FRAGMENTED MATTER AND METHODS OF MANUFACTURE AND USE > Claims

1. (canceled)
- 3. The mechanical pump of claim 1, wherein the inner tube has an outer diameter in the range from 0.5 mm to 5 mm, and the coiled rotor has a pitch in the range from 1 to 50 turns/cm.
  - 5. The mechanical pump of claim 3, wherein the first and second coiled rotors are counterwound.
    - 7. The mechanical pump of claim 5, wherein a distal portion of the coiled rotor is unattached to the inner tube to provide a whip element as the pump is rotated.
      - 9. The mechanical pump of claim 7, wherein the coiled rotor element comprises a single filament, a multi-filar, stacked filaments, or multiple filament cable.
  - 6. The mechanical pump of claim 3, wherein the first and second coiled rotors are co-wound.
- 4. The mechanical pump of claim 1, further comprising a second coiled rotor element disposed within the central lumen of the inner tube.
- 8. The mechanical pump of claim 1, wherein the inner tube comprises a braided tube, a mesh tube, a coil, a stacked coil, or a coil-reinforced polymer tube.
  - 10. The mechanical pump of claim 8, wherein the filaments comprise a round wire, a ribbon wire, or a wire having an irregular cross-section.
2. A mechanical pump for use in a medical device comprising: an elongate hollow, flexible inner tube having a proximal end, a distal end, and a central lumen;a first coiled rotor element having a distal end and a proximal end disposed over an outer surface of the inner tube; anda jacket securing the coiled rotor element to the outer surface of the inner tube.
11. A method for transporting material between a target site in a lumen of a body and a location, external to the body, the method comprising: introducing a distal end of a mechanical pump to the target site, the mechanical pump including an elongate hollow, flexible tube, a coiled rotor element disposed over an outer surface of the tube, and a jacket securing the coiled rotor element to the outer surface of the tube; androtating the coiled rotor element within the body lumen to advance the material proximally away from the target site.
- 12. The method of claim 11, the mechanical pump further comprising a shaft and a helical rotor, wherein rotating the coiled rotor element further comprises rotating a macerator attached at a distal end of the coiled rotor element.
- 13. The method of claim 11, the mechanical pump further comprising a clearing element comprising a cutting disk attached to the coiled rotor element.
14. A kit for transporting material between a target site in a lumen of a body and a location, external to the body, the kit comprising: a mechanical pump including an elongate hollow, flexible tube, a coiled rotor element disposed over an outer surface of the tube, and a jacket securing the coiled rotor element to the outer surface of the tube; and instructions for use that direct an operator to introduce a distal end of the mechanical pump to the target site; androtate the coiled rotor element within the body lumen to advance the material proximally away from the target site.
- 15. The kit of claim 14, the mechanical pump further comprising a shaft and a helical rotor, wherein rotating the coiled rotor element further comprises rotating a macerator attached at a distal end of the coiled rotor element.
- 16. The kit of claim 14, the mechanical pump further comprising a clearing element comprising a cutting disk attached to the coiled rotor element.
