1. A method of manufacturing a vascular treatment device, the method comprising:

  • cutting a first pattern of longitudinally-spaced rows each consisting essentially of two kerfs and two stems into a hypotube, the two kerfs in each of the rows of the first pattern having substantially the same circumferential length, the stems of the first pattern offset by a first value in a first circumferential direction; and

    cutting a second pattern of longitudinally-spaced rows each consisting essentially of two kerfs and two stems into the hypotube, the two kerfs in each of the rows of the second pattern having substantially the same circumferential length, the stems of the second pattern offset by a second value in a second circumferential direction opposite the first circumferential direction, wherein the first value is different than the second value, the rows of the second pattern singly interspersed with the rows of the first pattern.
