HANDPIECE ASSEMBLY FOR ARTICULAR INJECTION SYSTEMS
First Claim
1. A handpiece assembly for simultaneous or sequential delivery of multiple fluids into a joint, comprising:
- a core, a clip, a disposable tip, a needle, a first lumen and a second lumen;
wherein the core comprises at least one controller;
wherein said at least one controller controls a rate of flow of at least one of a first fluid and a second fluid;
wherein said first fluid is configured to flow through the first lumen;
wherein said second fluid is configured to flow through the second lumen;
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.

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.

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 at least one controller positioned along the outer housing, said at least one controller being configured to selectively regulate a flow of fluids through at least one of the first conduit and the second conduit; wherein the handpiece device is configured to deliver fluids through the first and second conduits to the needle simultaneously or sequentially; wherein each of said conduits comprises a valve to prevent fluid backflow toward the fluid delivery module; and wherein the needle is configured to be positioned within a joint to selectively deliver fluids to said joint. - View Dependent Claims (11, 12, 13, 14, 15)

16. An injection system for simultaneous or sequential delivery of different fluids into a patient, comprising:
-
a fluid delivery module configured to receive a first container and at least a second container; wherein the fluid delivery module comprises a first reservoir and at least a second reservoir, said first reservoir configured to be placed in fluid communication with a first fluid contained within said first container, and said second reservoir configured to be placed in fluid communication with a second fluid contained within said second container when said first and second containers are secured to said fluid delivery module; and a handpiece comprising a core, a clip, a disposable tip, a needle positioned at a distal end of said disposable tip, a first conduit and at least a second conduit; wherein the core comprises at least one controller configured to control a rate of flow of fluids through at least one of the first conduit and the second conduit; wherein the first fluid is configured to flow through the first conduit; wherein the second fluid is configured to flow through the second conduit; wherein said first and second conduits are configured to direct said fluids from the fluid delivery module, through the clip, through the disposable tip and to the needle; wherein said at least one controller controls whether the first and second fluids are delivered from the fluid delivery module to the needle simultaneously or sequentially; wherein the simultaneous delivery of said fluids is performed by combining the first and second fluids in the handpiece; wherein the core is in data communication with the fluid delivery module; wherein each of said conduits comprises a valve to prevent backflow of said fluids from the handpiece toward the fluid delivery module; wherein said disposable tip is configured to be removably attached to the clip; and 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 the patient. - View Dependent Claims (17, 18, 19, 20, 21)
