Imaging-guided anesthetic injection method
First Claim
1. A method of delivering an anesthetic to a subject using an imaging-guided injection system comprising:
- securing a container containing an anesthetic to an injection system;
wherein the container is configured to be secured to a loading area of a fluid delivery module of the injection system, said loading area being configured to receive various sizes and shapes of the container;
wherein the fluid delivery module comprises at least one interior reservoir, wherein the at least one interior reservoir is configured to be placed in fluid communication with the container when said container is properly secured to the at least one loading area;
wherein at least one slidably movable member is configured to be moved within or out of the at least one interior reservoir to selectively transfer a volume of the anesthetic either into or out of the at least one interior reservoir, wherein movement of the at least one slidably movable member relative to the at least one interior reservoir changes an effective volume of the at least one interior reservoir;
wherein the at least one slidably movable member is configured to be moved using at least one motor;
wherein a volume of the anesthetic transferred out of the at least one interior reservoir is configured to be delivered to at least one conduit, said at least one conduit being configured to be placed in fluid communication with the at least one reservoir, said at least one conduit comprising a distal end;
securing a needle to the distal end of the at least one conduit;
transferring a volume of the anesthetic from the container into the at least one interior reservoir;
transferring a volume of the anesthetic out of the at least one interior reservoir and into the at least one conduit;
placing the needle within an anatomy of the subject for the subsequent delivery of the anesthetic through the at least one conduit and the needle;
manipulating at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to a target anatomical location of the subject;
wherein the injection system comprises a display configured to provide status information related to the delivery of the anesthetic to the target anatomical location; and
wherein the injection system is configured to be placed in data communication with an imaging device to assist in accurately advancing the needle into the anatomy of the subject.

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 method of delivering an anesthetic to a subject using an imaging-guided injection system comprising:
-
securing a container containing an anesthetic to an injection system; wherein the container is configured to be secured to a loading area of a fluid delivery module of the injection system, said loading area being configured to receive various sizes and shapes of the container; wherein the fluid delivery module comprises at least one interior reservoir, wherein the at least one interior reservoir is configured to be placed in fluid communication with the container when said container is properly secured to the at least one loading area; wherein said at least one interior reservoir comprises at least one plunger, wherein movement of the at least one plunger within or out of the at least one interior reservoir changes an effective volume of the at least one interior reservoir; wherein at least one motor is configured to selectively move the at least one plunger to mechanically transfer a volume of the anesthetic either into or out of the at least one interior reservoir, wherein a transfer of the volume of the anesthetic is performed mechanically; wherein a volume of the anesthetic transferred out of the at least one interior reservoir is configured to be delivered to at least one conduit, said at least one conduit being configured to be placed in fluid communication with the at least one reservoir, said at least one conduit comprising a distal end; securing a needle to the distal end of the at least one conduit; transferring a volume of the anesthetic from the container into the at least one interior reservoir; transferring a volume of the anesthetic out of the at least one interior reservoir and into the at least one conduit; placing the needle within an anatomy of the subject for the subsequent delivery of the anesthetic through the at least one conduit and the needle; manipulating at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to a target anatomical location of the subject; wherein the injection system comprises a display configured to provide status information related to the delivery of the anesthetic to the target anatomical location; wherein the injection system is configured to be placed in data communication with an imaging device to assist in accurately advancing the needle into the anatomy of the subject; wherein the display is additionally configured to provide at least one real-time image of the anatomy of the subject obtained by the imaging device; and wherein the system is configured to detect a back-pressure associated with a delivery of the anesthetic through the at least one conduit. - View Dependent Claims (16, 17, 18, 19, 20)
