1. A method of manufacturing a vascular treatment device, the method comprising: holding a hypotube using at least one bushing and at least one collet;cutting a pattern comprising a plurality of kerfs into the hypotube, wherein cutting the pattern comprises: directing a focused laser beam at the hypotube, the focused laser beam creating a heat impact puddle, the heat impact puddle being less than a width and a length of each of the plurality of kerfs, andlongitudinally and rotationally moving the hypotube in a design such that the focused laser beam cuts the hypotube to form the plurality of kerfs; andduring cutting the pattern, flowing fluid through the hypotube,wherein holding the hypotube using the at least one bushing and the at least one collet comprises inhibiting motion of the hypotube prior to cutting of the hypotube by the focused laser beam and at least one of reducing sag of the hypotube and maintaining tension on the hypotube as the hypotube is advanced towards the focused laser beam, and wherein longitudinally and rotationally moving the hypotube comprises advancing the hypotube towards the focused laser beam using a hypotube dispenser comprising hypotube clamp and a motor. 2. The method of claim 1, wherein directing the focused laser beam comprises creating the heat impact puddle inward of edges of the plurality of kerfs, and wherein cutting the pattern comprises cutting away the heat impact puddle. 3. The method of claim 1, wherein directing the focused laser beam comprises creating the heat impact puddle at edges of the plurality of kerfs. 4. The method of claim 1, wherein directing the focused laser beam comprises creating the heat impact puddle at corners of the plurality of kerfs. 5. The method of claim 1, wherein the design comprises outlining edges of the plurality of kerfs. 6. The method of claim 1, wherein the design comprises moving the hypotube comprises relatively moving the focused laser beam diagonal to the plurality of kerfs. 7. The method of claim 1, wherein the design comprises a spiral. 8. The method of claim 1, wherein holding the hypotube comprises adjusting a diameter of an aperture of the at least one collet. 9. The method of claim 1, wherein flowing the fluid comprises adjusting a height of a reservoir containing the fluid. 10. The method of claim 1, wherein flowing the fluid comprises adjusting a height of a water inlet gate between a reservoir containing the fluid and the hypotube. 11. The method of claim 1, wherein the width of the kerfs is between about 0.02 mm and about 0.03 mm. 12. The method of claim 1, wherein a ratio of the width of the kerfs to a circumferential thickness of struts at least partially defined by the kerfs is between about 1:1 and about 2:1. 13. A method of manufacturing a vascular treatment device, the method comprising: cutting a pattern into a hypotube, wherein the pattern comprises: a first pattern of longitudinally-spaced rows each comprising two kerfs and two stems, the two stems in each of the rows of the first pattern circumferentially 180° apart, the stems of the first pattern offset in a first circumferential direction, anda second pattern of longitudinally-spaced rows each comprising two kerfs and two stems, the two stems in each of the rows of the second pattern circumferentially 180° apart, the rows of the second pattern interspersed with the rows of the first pattern, the stems of the second pattern offset in a second circumferential direction opposite the first circumferential direction; andduring cutting the pattern, flowing fluid through the hypotube. 14. The method of claim 13, wherein each of the rows is angled with respect to a longitudinal axis of the hypotube. 15. The method of claim 13, wherein the kerfs in each of the rows of the first pattern and the second pattern have rounded edges. 16. The method of claim 13, wherein a pitch of the longitudinally-spaced rows of the first pattern and the second pattern varies longitudinally along the hypotube. 17. A method of manufacturing a vascular treatment device, the method comprising: holding a hypotube using at least one bushing and at least one collet;cutting a pattern comprising a plurality of kerfs into the hypotube, wherein cutting the pattern comprises: directing a focused laser beam at the hypotube, the focused laser beam creating a heat impact puddle, the heat impact puddle being less than a width and a length of each of the plurality of kerfs, wherein a ratio of the width of the kerfs to a circumferential thickness of struts at least partially defined by the kerfs is between about 1:1 and about 2:1, andlongitudinally and rotationally moving the hypotube in a design such that the focused laser beam cuts the hypotube to form the plurality of kerfs; andduring cutting the pattern, flowing fluid through the hypotube. 18. The method of claim 17, wherein directing the focused laser beam comprises creating the heat impact puddle inward of edges of the plurality of kerfs, and wherein cutting the pattern comprises cutting away the heat impact puddle. 19. The method of claim 17, wherein directing the focused laser beam comprises creating the heat impact puddle at edges of the plurality of kerfs. 20. The method of claim 17, wherein directing the focused laser beam comprises creating the heat impact puddle at corners of the plurality of kerfs. 21. The method of claim 17, wherein the design comprises outlining edges of the plurality of kerfs. 22. The method of claim 17, wherein the design comprises moving the hypotube comprises relatively moving the focused laser beam diagonal to the plurality of kerfs. 23. The method of claim 17, wherein the design comprises a spiral. 24. The method of claim 17, wherein holding the hypotube comprises adjusting a diameter of an aperture of the at least one collet. 25. The method of claim 17, wherein flowing the fluid comprises adjusting a height of a reservoir containing the fluid. 26. The method of claim 17, wherein flowing the fluid comprises adjusting a height of a water inlet gate between a reservoir containing the fluid and the hypotube. 27. The method of claim 17, wherein the width of the kerfs is between about 0.02 mm and about 0.03 mm.
