1. A device for treating a vessel, the device comprising:
- a hypotube comprising;
a proximal end, a distal end, a longitudinal axis, and a lumen,at least a portion of the hypotube comprising;
a first pattern comprising longitudinally-spaced rows, each of the rows of the first pattern comprising two kerfs and two stems, the two stems in each of the rows of the first pattern being circumferentially opposite, the stems of the first pattern offset in a first circumferential direction, anda second pattern comprising longitudinally-spaced rows, each of the rows of the second pattern comprising two kerfs and two stems, the two stems in each of the rows of the second pattern being circumferentially opposite, the stems of the second pattern offset in a second circumferential direction opposite the first circumferential direction, the rows of the second pattern singly alternatingly interspersed with the rows of the first pattern; and
a balloon radially outward of at least some of the first pattern and the second pattern of the portion of the hypotube.

Abstract
A device for treating a vessel may include a tubular member including a first portion, a second portion distal to the first portion, and a third portion distal to the second portion. The second portion may include a plurality of patterns each including longitudinally-spaced rows. Each of the rows may include two kerfs and two stems. The stems within each of the plurality of patterns may be offset in a circumferential direction, and the circumferential direction of at least two patterns of the plurality of patterns may be opposite. The second portion may further include an inflatable element radially outward of the tubular member.
