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 method of injecting a plurality of fluids into multiple patients using nonspecific fluid containers, comprising:

providing an injection system comprising a fluid delivery module and a handpiece;

wherein the handpiece comprises a clip, a disposable tip, a reusable core and at least one controller;

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

wherein said first container comprises a first fluid;

wherein said second container comprises a second fluid;

wherein said loading areas are configured to securely receive containers of various types, shapes and sizes;

wherein said fluid delivery module is configured to receive instructions for delivering the first and second fluids for a first patient;

wherein said fluid delivery module is configured to receive instructions for delivering the first and second fluids for a second patient;

wherein the instructions are modifiable between patients;

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

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

wherein the first and second reservoirs are positioned within a interior of the fluid delivery module;

wherein a distal end of the disposable tip of the handpiece is configured to receive a first needle for use with a first patient and a second needle for use with a second patient;

wherein the disposable tip is configured to be disposed between patients;

wherein the disposable tip comprises a valve to prevent reverse flow of the first and second fluids from the needle into the clip of the handpiece;

wherein said handpiece is configured to be in fluid communication with the first and second reservoirs of the fluid delivery module;

wherein said handpiece is maneuverable to position the first or second needle within the patient; and

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

2. The method of claim 1, wherein the at least one controller of the handpiece comprises at least one button, said at least one button being configured to receive instructions for controlling at least one aspect of an injection procedure.

3. The method of claim 1, wherein the fluid delivery module is configured to simultaneously or sequentially transfer a predetermined volume of the first fluid and the second fluid to a patient.

4. The method of claim 1, wherein the fluid delivery module comprises a motor to facilitate the delivery of the first and second fluids to a patient.

5. The method of claim 1, wherein the first fluid comprises an anesthetic.

6. The method of claim 1, wherein the second fluid comprises a steroid.

7. The method of claim 1, wherein the first and second fluids are delivered simultaneously to a joint in a patient.

8. The method of claim 1, wherein the first and second fluids are delivered sequentially to a joint in a patient.

9. The method of claim 1, wherein the injection system further comprises a display configured to display information regarding the delivery of the first and second fluids to a patient.

10. The method of claim 1, wherein the first container comprises a nonspecific container.

11. The method of claim 10, wherein the nonspecific container comprises a vial as supplied by a drug manufacturer.

12. The method of claim 1, further comprising monitoring a position of the distal tip of the needle using an imaging device operatively connected to said injection system to accurately locate a target anatomical location of a patient.

13. The method of claim 12, wherein the imaging device comprises an ultrasound device.
