Delivery device

A delivery device for intravenous delivery of microparticles to a patient, the delivery device being fluidly connectable to an injection medium, the delivery device comprising:

• a fluid inlet fluidly connectable to the injection medium, the fluid inlet fluidly connected to a first fluid flow path and to a second fluid flow path;
• a fluid outlet;
• a fluid mixer fluidly connected to the first fluid flow path, to the second fluid flow path, and to the fluid outlet;
• and
• a source of microparticles fluidly located along the second fluid flow path between the fluid inlet and the fluid mixer;
• wherein, when fluid flows through the first and second fluid flow paths:
• the injection medium flowing through the second fluid flow path fluidly drives microparticles from the source of microparticles into the fluid mixer, and
• the fluid outlet dispenses to the patient an injection medium that comprises the microparticles.

A delivery device for intravenous delivery of microparticles to a patient, the delivery device being fluidly coupleable to an injection medium, the delivery device comprising:

• a fluid inlet fluidly coupleable to the injection medium, the fluid inlet fluidly coupled to a transport fluid flow path and to a displacement fluid flow path,
• a fluid outlet,
• a fluid mixer fluidly coupling the transport fluid flow path, the displacement fluid flow path, and the fluid outlet, and
• a source of microparticles fluidly coupled to the fluid mixer,
• the displacement fluid flow path for driving, utilizing the injection medium flowing through the displacement fluid flow path, the microparticles into the fluid mixer and out the fluid outlet via the injection medium flowing through the transport fluid flow path.

A device for loading with microparticles for intravenous delivery to a patient, the device being fluidly coupleable to an injection medium, the delivery device comprising:

• a first fluid inlet fluidly coupleable to the injection medium, the fluid inlet fluidly coupled to a transport fluid flow path and to a displacement fluid flow path;
