Fluid Processing Systems Including An Electroporation Device

A fluid processing system, comprising:

• a separation device;
• a mononuclear cell product processing device;
• a pump assembly including a plurality of pumps;
• and
• a controller programmed to
• actuate the pump assembly to convey blood from a blood source into the separation device,
• actuate the separation device to separate a mononuclear cell product from the blood, and
• actuate the pump assembly to convey at least a portion of the mononuclear cell product through the mononuclear cell product processing device to modify a genome of at least one of the cells of the mononuclear cell product and create a modified mononuclear cell product, wherein the controller is programmed to selectively actuate the pump system to convey said at least a portion of the mononuclear cell product through the mononuclear cell product processing device in a first direction to modify the genome of said at least one of the cells of the mononuclear cell product and actuate the pump system to convey said at least a portion of the mononuclear cell product through the mononuclear cell product processing device in a second direction that is opposite to the first direction to modify the genome of said at least one of the cells of the mononuclear cell product.
