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.
