In some examples, a catheter may include a catheter body, a first expandable member, and a second expandable member. The catheter body may define a first lumen, a second lumen, a delivery port, and a surface extending from the delivery port into the first lumen. The first lumen may define a first central longitudinal axis. The second lumen may define a second central longitudinal axis spaced from the first central longitudinal axis in a direction orthogonal to the second central longitudinal axis. The delivery port may be in fluid communication with the first lumen. The surface extending from the delivery port into the first surface may be oriented at an obtuse or acute angle relative to the first central longitudinal axis.
