1. A method of transporting fluid between a treatment site of a patient and a location outside of the patient, the method comprising: providing a catheter having a connection end locatable outside of the patient, an elongated fluid conduit, and a terminal end locatable at the treatment site, the conduit defining a fluid path between the connection end and the terminal end, the terminal end comprising, a first fluid exchange portion having a wall defining an outer surface and an inner lumen in fluid communication with the elongated fluid conduit, the first fluid exchange portion having at least one opening communicating between the inner lumen and the outer surface of the wall, and a barrier connected to and extending from the first fluid exchange portion; placing the terminal end from a location outside of the patient, through a tissue opening, to a location inside of the patient, at the treatment site; positioning the barrier to bias fluid flow at the treatment site in a preferential direction or to impede fluid flow in a non-preferential direction; and extracting the terminal end through the tissue opening to transition the barrier from a deployed configuration to a collapsed configuration.
