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.

at least one fluid outlet in fluid communication with the first and second reservoirs;

wherein at least a portion of fluid contained within a container secured to the first loading area is configured to be transferred to an interior of the first reservoir when the first movable member is moved in a first direction;

wherein at least a portion of fluid contained within the first reservoir is configured to be transferred to the at least one fluid outlet when the first movable member is moved in a second direction, wherein said second direction is generally opposite of said first direction.

2. The cassette of claim 1, wherein the first and second movable members are configured to be moved independently by the at least one motor.
