Methods, storage devices, and infusion systems for therapeutic or diagnostic agents

An assembly configured to connect to a delivery system for delivering a therapeutic or diagnostic agent, the assembly comprising:

• a storage device containing the therapeutic or diagnostic agent;
• and
• a fluid cassette fluidly connectable to the storage device for accessing the therapeutic or diagnostic agent,
• wherein the storage device comprises:
• a housing having a chamber defined therein;
• a vessel positioned within the chamber, the vessel having an interior configured for receiving the therapeutic or diagnostic agent and an access port for accessing the interior;
• and
• a door associated with the housing, the door movable relative to the housing between a closed position and an open position, wherein, in the closed position, the door covers an opening in the housing to enclose the chamber of the housing, and wherein, in the open position, the door reveals the opening in the housing for accessing the access port of the vessel,
• wherein the fluid cassette comprises:
• a vessel access member, a metering device, and a fluid path set fluidly connecting the vessel access member to the metering device;
• and
• an enclosure enclosing the vessel access member, the metering device, and the fluid path set, and
• wherein the storage device and the fluid cassette are configured to connect to the delivery system such that the door of the storage device is accessible by an access mechanism of the delivery system and such that the vessel access member and the metering device of the fluid cassette are accessible by a delivery mechanism of the delivery system.

A delivery system for delivering a therapeutic or diagnostic agent, the delivery system comprising:

• an injector having a delivery mechanism and an access mechanism;
• and
• a fluid delivery assembly removably connectable to the injector, the fluid delivery assembly comprising:
• a storage device containing the therapeutic or diagnostic agent;
• and
• a fluid cassette fluidly connectable to the storage device for accessing the therapeutic or diagnostic agent,
• wherein the storage device comprises:
• a housing having a chamber defined therein;
• a vessel positioned within the chamber, the vessel having an interior configured for receiving the therapeutic or diagnostic agent and an access port for accessing the interior;
• and
• a door associated with the housing, the door movable relative to the housing via the access mechanism of the injector between a closed position and an open position, wherein, in the closed position, the door covers an opening in the housing to enclose the chamber of the housing, and wherein, in the open position, the door reveals the opening in the housing for accessing the access port of the vessel,
• wherein the fluid cassette comprises:
• a vessel access member, a metering device, and a fluid path set fluidly connecting the vessel access member to the metering device;
• and
• an enclosure enclosing the vessel access member, the metering device, and the fluid path set, and
• wherein the vessel access member and the metering device of the fluid cassette are accessible by the delivery mechanism of the injector for fluidly connecting the interior of the vessel with the metering device via the fluid path set.
