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.

Claims

1. A system for injecting at least two different medicaments into a patient through a single needle penetration using nonspecific fluid containers, comprising:

a fluid delivery module and a handpiece, wherein the fluid delivery module comprises a first loading area configured to secure a first fluid container and a second loading area configured to secure a second fluid container;

wherein the first fluid container comprises a first medicament;

wherein the second fluid container comprises a second medicament;

wherein the first loading area and the second loading area are configured to securely receive containers of various sizes and shapes;

wherein a disposable needle is configured to removably attach to a distal end of said handpiece, said needle configured to be positioned within an anatomy of the patient;

wherein said fluid delivery module is configured to receive instructions for delivering the first and second medicaments to the needle through an interior portion of the handpiece;

first and second reservoirs positioned within an interior of the fluid delivery module;

wherein the fluid delivery module is configured to transfer a portion of the first medicament from the first fluid container to the first reservoir;

wherein the fluid delivery module is configured to transfer a portion of the second medicament from the second fluid container to the second reservoir;

a first conduit configured to selectively place the handpiece in fluid communication with the first reservoir of the fluid delivery module; and

a second conduit configured to selectively place the handpiece in fluid communication with the second reservoir of the fluid delivery module;

wherein the first and second conduits are positioned within the interior portion of said handpiece;

wherein said fluid delivery module is configured to combine the first and second medicaments prior to delivery to the patient or configured to administer the first and second medicaments sequentially, depending on the instructions received by at least one of the fluid delivery module and the handpiece; and

wherein each of said conduits comprises a valve to prevent backflow of said medicaments toward the fluid delivery module.

2. The system of claim 1, wherein the handpiece comprises at least one controller, said controller being configured to receive at least one instruction related to an injection procedure.

3. The system of claim 2, wherein the at least one controller comprises at least one button, dial, knob, switch, rollerball or rollerwheel.

4. The system of claim 1, wherein the fluid delivery module comprises a motor to facilitate delivery of the first and second medicaments from said reservoirs to said conduits and said needle.

5. The system of claim 1, wherein the first and second medicaments are delivered simultaneously to a joint of the patient.

6. The system of claim 1, wherein the first and second medicaments are delivered sequentially to a joint of the patient.

7. The system of claim 1, wherein the fluid delivery module comprises a display configured to provide status information of an injection procedure.

8. The system of claim 7, wherein said status information comprises a volume of the first or second medicaments delivered through the handpiece assembly or a volume remaining in the first and second reservoirs of the fluid delivery module.

9. The system of claim 1, wherein at least one of the first fluid container and the second fluid container is a nonspecific fluid container.

10. The system of claim 1, wherein at least one of the first fluid container and the second fluid container is an original manufacturer'"'"'s vial

11. The system of claim 1, wherein the fluid delivery module is in data communication with an imaging device configured to locate a targeted joint location within the patient.

12. The system of claim 11, wherein the imaging device comprises an ultrasound device.

13. A system for injecting two or more different fluids into a patient using single needle penetration, comprising:

a fluid delivery module having a base and a disposable portion, the disposable portion comprising;

at least a first loading area and a second loading area, each of said loading areas configured to securely receive a container;

a first reservoir configured to be placed in fluid communication with an interior of a first container securely positioned within the first loading area, and a second reservoir configured to be placed in fluid communication with an interior of a second container securely positioned with the second loading area;

wherein the first reservoir comprises a first outlet, and the second reservoir comprises a second outlet;

wherein the base of the fluid delivery module comprises a fluid transfer device adapted to selectively transfer fluids from the first reservoir to the first outlet and from the second reservoir to the second outlet; and

wherein the disposable portion is configured to be removably positioned within a recess of the base;

a handpiece assembly comprising;

a handle portion configured to be grasped and manipulated by a user, said handle portion comprising an interior and a chamber;

a tip having a proximal end and a distal end, said tip further comprising at least one internal passage, said proximal end configured to be secured to the handle portion, and said internal passage being in fluid communication with the chamber when the tip is secured to the handle portion; and

a needle extending from the distal end of the tip, said needle configured to be positioned within an anatomy of the patient; and

a first conduit placing the first outlet in fluid communication with the chamber of said handpiece assembly, and a second conduit placing the second outlet in fluid communication with said chamber;

wherein the handpiece assembly comprises at least one controller, said controller being configured to control the delivery of fluids from at least one of the first and second reservoirs through the chamber and to the needle;

wherein fluids conveyed within the first and second conduits are maintained separate upstream of the chamber; and

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

14. The system of claim 13, wherein the chamber is located at or near an interface between the handle portion and the tip of the handpiece assembly.

15. The system of claim 13, wherein the chamber is located upstream of an interface between the handle portion and the tip of the handpiece assembly.

16. The system of claim 13, wherein said loading areas are configured to receive a nonspecific container.

17. The system of claim 16, wherein the nonspecific container comprises a vial as originally supplied by a drug manufacturer.

18. The system of claim 13, wherein the at least one controller comprises at least one button positioned along an exterior surface of the handle portion of the handpiece assembly.

19. The system of claim 13, wherein the injection system is operatively connected to an imaging device configured to assist a user in advancing the needle to a desired anatomical position within the patient.

20. The system of claim 13, wherein at least one of said loading areas is configured to continuously or intermittently rotate a fluid container positioned therein in order to maintain a fluid contained within said loading area mixed.
