Articular injection system
First Claim
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 needle is positioned along a distal end of said handpiece, said needle being 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 at least a portion of the first medicament from the first fluid container to the first reservoir;
wherein the fluid delivery module is configured to transfer at least a portion of the second medicament from the second fluid container to the second reservoir;
at least one fluid passage positioned within the handpiece, said at least one fluid passage being in fluid communication with each of the first and second reservoirs;
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
at least one movable member slidably positioned within each of the first and second reservoirs;
wherein the at least one movable member is configured to be mechanically moved into or out of the first or second reservoir; and
wherein the first medicament is transferred from the first fluid container to the first reservoir of the fluid delivery module when the movable member is moved in a first direction.

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.

15. 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 removable portion, the removable 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 removable portion is configured to be removably positioned within a recess of the base; a first movable member positioned within the first reservoir; wherein the movable member is configured to mechanically move within an interior of the first reservoir; wherein fluid contained within a container secured to the first loading area is configured to be transferred to an interior of the first reservoir when the first movable member is moved in a first direction; a handpiece assembly comprising a handle portion and a tip extending from a distal end of said handle portion; wherein the needle is configured to be positioned within an anatomy of the patient; and at least one fluid conduit placing the first outlet and the second outlet in fluid communication with the chamber of said handpiece assembly; and at least one controller, said controller being configured to control the delivery of fluids from at least one of the first and second reservoirs to the needle. - View Dependent Claims (16, 17, 18, 19, 20, 21)
