wherein the fluid delivery module comprises a first loading area configured to receive a first container and a second loading area configured to receive a second container;
wherein the first container comprises a first medicament;
wherein the second container comprises a second medicament;
the first loading area being configured to securely receive various sizes and shapes of the first container;
the second loading area being configured to securely receive various sizes and shapes of the second container;
wherein the injection system is configured to receive instructions for delivering the first and second medicaments;
wherein the fluid delivery module is configured to transfer at least a portion of the first medicament from the first container to a first reservoir of the fluid delivery module;
wherein the fluid delivery module is configured to transfer at least a portion of the second medicament from the second container to a second reservoir of the fluid delivery module;
wherein the handpiece assembly is configured to receive a needle;
wherein the handpiece assembly is configured to selectively be in fluid communication with the first and second reservoirs of the fluid delivery module using tubing situated between the needle and the first and second reservoirs;
wherein the handpiece assembly is adapted to be maneuvered in order to position the needle within a target location of a patient;
wherein, based on the instructions received, the injection system either (i) combines the first and second medicaments prior to delivery to the patient so that first and second medicaments are simultaneously delivered to the patient, or (ii) delivers the first and second medicaments sequentially;
wherein a volume of the first medicament is transferred from the fluid delivery module to the patient through the needle of the handpiece assembly based at least in part on instructions provided to the injection system; and
wherein a volume of the second medicament is transferred from the fluid delivery module to the patient through the needle of the handpiece assembly based at least in part on instructions provided to the injection system;
a first plunger slidably disposed within the first reservoir;
a second plunger slidably disposed within the second reservoir; and
at least one motor of the fluid delivery module configured to slidably move at least one of the first plunger and the second plunger within the corresponding reservoir to mechanically transfer at least one of the first medicament and the second medicament to and through the handpiece assembly.

Abstract
Systems for injecting fluids and/or other materials into a targeted anatomical location, in particular, an intra-articular space, include a handpiece assembly having a proximal end and a distal end, a needle extending from the distal end of the handpiece assembly, a fluid delivery module comprising a cassette and a fluid transfer device. A conduit is generally configured to place the fluid delivery module in fluid communication with the handpiece assembly. Medications, formulations and/or other fluids or materials contained within vials that are secured to the fluid delivery module can be selectively delivered into an anatomy through a needle located at the distal end of the handpiece assembly. In some embodiments, ultrasound or other imaging technologies can be used to locate a joint or other targeted anatomical location.
