IMAGING-GUIDED ANESTHESIA INJECTION SYSTEMS AND METHODS
First Claim
1. An imaging-guided injection system for delivering an anesthetic to a target anatomical location of a patient, the system comprising:
- a fluid delivery module comprising at least one loading area configured to receive a container comprising an anesthetic, the at least one loading area being configured to securely receive various sizes and shapes of the container;
at least one fluid reservoir within an interior of the fluid delivery module;
at least one fluid conduit configured to be placed in fluid communication with the at least one fluid reservoir, said at least one fluid conduit comprising a distal end;
wherein the fluid delivery module is configured to selectively transfer at least a portion of the anesthetic from the container through the at least one fluid conduit via the at least one fluid reservoir;
wherein the distal end of the at least one fluid conduit is configured to removably receive a stimulation needle, said stimulation needle being configured to provide electrical stimulation to an anatomy of the patient;
wherein the fluid delivery module comprises at least one motor, said at least one motor being configured to facilitate the transfer of the fluid through the at least one fluid conduit and to the stimulation needle;
at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to the target anatomical location of the patient according to a delivery scheme; and
a display configured to provide status information related to the delivery of the anesthetic to the target anatomical location;
wherein the system is configured to be placed in data communication with an imaging device to assist in accurately advancing the stimulation needle into the anatomy of the patient.

Abstract
Devices and systems for injecting fluids, such as anesthetics, to or near nerve tissue or other targeted anatomical location are disclosed herein. A conduit is generally configured to place the fluid delivery module in fluid communication with a needle that is configured to be inserted into the patient'"'"'s anatomy. One or more medicaments (e.g., anesthetics) and/or other materials contained within containers (e.g., vials) that are secured to the injection system can be selectively delivered into an anatomy through the needle. Nerve stimulation and/or imaging technologies (e.g., ultrasound) can be used to locate a targeted anatomical location. Aspiration can be used to confirm needle location. An overlay on the imaging display can include, in addition to real-time imaging data, data and other information relating to back pressure at or near the needle tip, volumes or other amounts of fluids delivered by and remaining within the system, stimulation level and/or the like.
