Abstract

Claims (30)

1. A system for removing undesirable material from a body, the system comprising:

an outer shaft, an intermediate shaft, and an inner shaft;

wherein the intermediate shaft is configured to be coaxially inserted within a lumen of the outer shaft and coaxially over the inner shaft, and wherein the intermediate shaft is uncoupled at a distal end from the outer shaft and the inner shaft, and is independently translatable and rotatable relative to the outer shaft and the inner shaft;

a helical macerator member at the distal end of the intermediate shaft;

an aspiration source configured to be operatively fluidly coupled to the lumen of the outer shaft and generate a suction force within the outer shaft to draw undesirable material into the outer shaft; and

wherein the helical macerator member is configured to operatively engage the undesirable material within the outer shaft, and wherein the helical macerator member is configured to disrupt the undesirable material within the outer shaft upon rotation of the intermediate shaft.

2. The system of claim 1 , wherein the suction force within the outer shaft is configured to suction the disrupted undesirable material.

3. The system of claim 1 , wherein the outer shaft includes a reinforcing element having at least one wire member.

4. The system of claim 3 , wherein the outer shaft includes an expandable element.

5. The system of claim 4 , wherein the expandable element is positioned at a distal end of the outer shaft.

6. The system of claim 4 , wherein the expandable element comprises a cover composed of a permeable material or non-permeable material.

7. The system of claim 3 , wherein the at least one wire member includes a plurality of wires having a proximal wire section and a distal wire section, and wherein a number of interconnection locations of the proximal wire section is greater than a number of interconnection locations of the distal wire section.

8. The system of claim 3 , wherein the at least one wire member includes shape memory material, nitinol, stainless steel or plastic.

9. The system of claim 1 , wherein the intermediate shaft is capable of manual rotation.

10. The system of claim 1 , wherein the helical macerator member is configured to macerate the undesirable material within an annular space defined between the helical macerator member and the outer shaft.

11. The system of claim 1 , wherein the intermediate shaft is configured to be manually rotated to disrupt the undesirable material within the outer shaft.

12. A system for removing undesirable material from a body, the system comprising:

an outer shaft, an intermediate shaft, and an inner shaft, the outer shaft being an elongate outer shaft and the inner shaft being an elongate inner shaft;

wherein the intermediate shaft is configured to be coaxially inserted within a lumen of the outer shaft and coaxially over the inner shaft, and wherein the intermediate shaft is uncoupled at a distal end from the outer shaft and the inner shaft, and is independently translatable and rotatable relative to the outer shaft and the inner shaft

a helical macerator member at the distal end of the intermediate shaft;

an aspiration source configured to be operatively fluidly coupled to the lumen of the outer shaft and generate a suction force within the outer shaft to draw undesirable material into the outer shaft; and

wherein the helical macerator member is configured to operatively engage the undesirable material within the outer shaft, and wherein the helical macerator member is configured to disrupt the undesirable material within the outer shaft upon rotation of the intermediate shaft.

13. The system of claim 12 , wherein the suction force within the outer shaft is configured to suction the disrupted undesirable material.

14. The system of claim 12 , wherein the reinforcing element includes at least one wire member.

15. The system of claim 14 , wherein the outer shaft includes an expandable element.

16. The system of claim 15 , wherein the expandable element is positioned at a distal end of the outer shaft.

17. The system of claim 15 , wherein the expandable element comprises a cover composed of a permeable material or non-permeable material.

18. The system of claim 14 , wherein the at least one wire member includes a plurality of wires having a proximal wire section and a distal wire section, and wherein a number of interconnection locations of the proximal wire section is greater than a number of interconnection locations of the distal wire section.

19. The system of claim 14 , wherein the at least one wire member includes shape memory material, nitinol, stainless steel or plastic.

20. The system of claim 12 , wherein the intermediate shaft is capable of manual rotation.
