METHODS OF INJECTING FLUIDS INTO JOINTS USING A HANDPIECE ASSEMBLY
First Claim
1. A method of injecting two or more fluids into a joint of a patient using a handpiece assembly, comprising:
- providing a handpiece assembly comprising a core, a clip, a disposable tip, a needle, a first conduit and a second conduit;
wherein a first fluid is configured to flow through said first conduit;
wherein a second fluid is configured to flow through said second conduit;
wherein the core comprises at least one controller configured to control a rate of flow of at least one of the first fluid and the second fluid through said conduits;
wherein the core is configured to be in data and fluid communication with a fluid delivery module;
wherein said first and second conduits are configured to convey said fluids through the clip and the disposable tip and to the needle;
wherein said conduits are routed through an interior of the handpiece assembly;
wherein each of said conduits comprises a valve to prevent backflow of said fluids toward a proximal end of said handpiece assembly;
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;
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;
positioning said needle into a joint of the patient; and
delivering a volume of at least one of the first fluid and the second fluid through said conduits to the needle;
wherein said at least one controller controls a rate of flow of at least one of a first fluid and a second fluid through said conduits;
wherein said at least one controller controls whether the first and second fluids are delivered simultaneously or sequentially; and
wherein the simultaneous delivery of said fluids is performed by combining the first and second fluids in 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.

12. A method of injecting two or more fluids into an anatomy using a handpiece assembly, comprising:
-
providing a handpiece assembly comprising a main body and a needle removably positioned at a distal end of said main body; wherein the handpiece assembly comprises a first conduit and at least a second conduit, said conduits positioned within an interior of said main body; wherein a first fluid is configured to flow through said first conduit; wherein a second fluid is configured to flow through said second conduit; wherein the main body comprises at least one button configured to control a rate of flow of at least one the first fluid and the second fluid through said conduits; wherein the handpiece assembly is configured to be in data and fluid communication with a fluid delivery module; wherein said first and second conduits are configured to convey said fluids to the needle; wherein each of said conduits comprises a valve to prevent backflow of said fluids toward a proximal end of said main body; wherein the needle is configured to be positioned within a target anatomical location to selectively deliver at least one said first fluid or said second fluid to said anatomical location; positioning said needle into an anatomy; wherein positioning said needle into an anatomy comprises using an imaging device to accurately locate said target anatomical location; and delivering a volume of at least one of the first fluid and the second fluid through said conduits to the needle; wherein said at least one button controls a rate of flow of at least one of a first fluid and a second fluid through said conduits; and wherein the simultaneous delivery of said fluids is performed by combining the first and second fluids in the handpiece assembly. - View Dependent Claims (13, 14, 15, 16, 17, 18)
