Abstract

Devices and systems for injecting fluids and/or other materials into a targeted anatomical location, in particular, a joint or intra-articular space, include a handpiece assembly having a needle extending from its distal end, 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. Medicaments, formulations and/or other fluids or materials contained within vials that are secured to a cassette or other portion of 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.

Claims18

Dependent claims

An injection system for delivering at least one fluid into a subject, comprising:

a fluid delivery module comprising a first loading area configured to receive a container, the fluid delivery module further comprising a first internal reservoir, the first internal reservoir being configured to selectively receive a volume of fluid contained within a container secured to the first loading area;
a handpiece assembly comprising at least one conduit, the at least one conduit comprising a distal end configured to receive a needle, wherein the at least one conduit of the handpiece assembly is configured to be placed in fluid communication with the first internal reservoir;
at least one controller configured to regulate, at least in part, a delivery of a fluid from the first internal reservoir to the at least one conduit of the handpiece assembly;
a fluid transfer device for selectively generating a vacuum and a positive pressure within the first internal reservoir;
wherein the fluid transfer device transfers a first volume of a fluid from a container secured to the first loading area to the first internal reservoir by generating a vacuum within the first internal reservoir;
and when the first volume of fluid is located in the first internal reservoir, the fluid transfer device transfers at least a portion of the first volume of the fluid transferred to the first internal reservoir to the at least one conduit of the handpiece assembly by generating a positive pressure within the first internal reservoir;
and
wherein the injection system is configured to generate a negative pressure within the at least one conduit in order to aspirate a bodily fluid of the subject at least partially through a needle secured along the distal end of the at least one conduit when the needle is positioned with the subject.
