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.

wherein said at least one controller controls whether the first and second fluids are delivered simultaneously or sequentially;

wherein the simultaneous delivery of said fluids is performed by combining the first and second fluids in the handpiece assembly;

wherein the core is in data communication with a fluid delivery module;

wherein said first and second lumens are configured to direct said fluids from the fluid delivery module, through the clip, through the disposable tip and to the needle;

wherein each of said lumens comprises a valve to prevent backflow of said fluids toward the fluid delivery module;

wherein said needle is configured to be removably attached to the disposable tip;

wherein said disposable tip is configured to be removably attached to the clip; and

wherein the needle is configured to be positioned within a joint to selectively deliver at least one said first fluid or said second fluid to said joint.

2. The handpiece assembly of claim 1, wherein the first and second fluids are configured to be combined within the clip under a simultaneous delivery scheme.

3. The handpiece assembly of claim 1, wherein the first and second fluids are configured to be combined at or near an interface between the clip and the disposable tip under a simultaneous delivery scheme.

4. The handpiece assembly of claim 1, wherein the first and second fluids are configured to be combined at a distal end of the clip, near an interface between the clip and the disposable tip under a simultaneous delivery scheme.

5. The handpiece assembly of claim 1, wherein the first and second fluids are maintained separate until immediately upstream of the disposable tip.

6. The handpiece assembly of claim 1, wherein the controller comprises at least one button.

7. The handpiece assembly of claim 6, wherein the button is configured to control the rate of flow of at least one of the first fluid and the second fluid between a no flow condition, a first flowrate condition and at least a second flowrate condition.

8. The handpiece assembly of claim 1, further comprising a third lumen;

wherein a third fluid is configured to be selectively conveyed through said third lumen;

wherein said at least one controller is configured to control a rate of flow of at least one of the first fluid, the second fluid and the third fluid;

wherein said fluids are configured to flow from the fluid delivery module to the needle sequentially or simultaneously.

9. The handpiece assembly of claim 8, wherein the core comprises:

a first controller configured to control a rate of flow of the first fluid;

a second controller configured to control a rate of flow of the second fluid; and

a third controller configured to control a rate of flow of the third fluid.

10. A handpiece device for use in an anatomical injection system, comprising:

an outer housing enclosing a handpiece interior, said outer housing configured to be grasped by a user;

a first conduit routed through the handpiece interior;

at least a second conduit routed through the handpiece interior;

a disposable tip having a first end and a second end, said first end configured to removably receive a needle, and said second end configured to secure to the outer housing;

wherein the first conduit is configured to place the needle in fluid communication with a first reservoir of a fluid delivery module;

wherein the second conduit is configured to place the needle in fluid communication with a second reservoir of the fluid delivery module; and
