Abstract: A medical device for the delivery of treatment fluid to body vessels is described. The device has a distal (21) and a proximal (20) end with a self-expanding, hollow tubular member (9) and a delivery catheter (10) suitable for deploying a self-expanding, tubular member (9). The tubular member (9) is configured to expand radially to form a central part (11) flanked by two annular ridges, which creates, in situ, an annular lumen that can apply treatment fluid locally to a vessel and a passageway that can maintain the flow of blood through the vessel. The device is particularly suited for minimally invasive and repeatable organ perfusion. A method for organ perfusion is also disclosed.
