An apparatus for blood oxygenation and delivery is provided. The apparatus advantageously comprises a liquid-to-liquid oxygenation assembly with a pressurizable chamber having inlets for a first gas-supersaturated fluid and a second fluid, such as blood. The inlets are advantageously positioned on the mixing chamber in such a way that the first fluid and the second fluid enter the mixing chamber normally to each other to promote mixing and liquid-to-liquid gas transfer. The apparatus also includes a delivery system coupled to the blood oxygenation assembly. The delivery system includes a generally tubular elongated member having a proximal end portion, a distal end portion, and a transition portion located between the proximal end portion and the distal end portion. The transitional portion is relatively flexible compared to the proximal end portion and is relatively stiff compared to the distal end portion. In another embodiment, the delivery system includes a generally tubular elongated member having a proximal end portion and a distal end portion with a plurality of holes.
