    Abstract: Methods and systems for bidirectional priming of a blood circuit while a catheter is connected to the circuit that delivers gas-enriched blood to a patient. The system primes the circuit while the catheter is connected to the circuit by controlling a first flow control mechanism to close to prevent blood flow through the draw line to a catheter and causes a pump to circulate blood in a first direction through a mixing chamber and/or through a bubble trap that removes air bubbles from the circuit. The system controls a second flow control mechanism to close to prevent blood flow in a return line to the catheter while causing the first flow control mechanism to open after the second flow control mechanism is closed and while causing the pump to circulate the blood in a second, opposite direction through the mixing chamber that removes air bubbles from the circuit.

    Abstract: A system delivers gas-enriched blood or liquid within the vasculature of a patient while partially obstructing a flow of blood within the vasculature of the patient. The system may include a first catheter configured for inserting into a vasculature of a patient to deliver gas-enriched blood or liquid to a region of the vasculature of the patient. The system may include a second catheter configured for inserting into the vasculature of the patient. The second catheter includes lumens and an occlusion structure configured to partially obstruct a flow of blood within the vasculature of the patient while allowing the first catheter to deliver the gas-enriched blood or liquid to the region of the vasculature, and to divert the blood flow to the region where the gas-enriched blood or liquid is delivered.
