Methods of injecting fluids into joints using a handpiece assembly
First Claim
1. A method of injecting two or more fluids into a joint of a patient using a handpiece assembly of an injection system, the method comprising:
- manipulating at least a portion of a handpiece assembly into an anatomy of a patient, said handpiece assembly comprising a main portion, a needle positioned along a distal end of said main portion, and at least one fluid conduit in fluid communication with said needle;
wherein a first fluid and at least a second fluid are configured to selectively flow through the at least one fluid conduit and to the needle;
wherein the first fluid and the second fluid are configured to be delivered through the at least one fluid conduit either simultaneously or sequentially, based at least in part on instructions provided by a user;
wherein the at least one fluid conduit is at least partially routed through an interior of the handpiece assembly;
wherein at least one electronic controller is positioned along the main portion of the handpiece assembly, wherein manipulation of the at least one electronic controller is configured to regulate a fluid delivery scheme for selectively delivering the first fluid and the second fluid to and through the needle;
wherein the fluid delivery scheme comprises an order in which the first and second fluids are delivered through the at least one fluid conduit and a flowrate at which the first and second fluids are delivered through the at least one fluid conduit;
wherein the at least one electronic controller is configured to be in data communication with a fluid delivery module;
wherein handpiece assembly is configured such that fluids are prevented from flowing proximally from the handpiece assembly through the at least one fluid conduit, toward the fluid delivery module;
wherein the needle is configured to be positioned within a joint to selectively deliver at least one of said first fluid and said second fluid to said joint;
positioning the needle into or near a joint of the patient; and
delivering a volume of at least one of the first fluid and the second fluid through the at least one conduit to and through the needle;
wherein the at least one electronic controller is selectively removable from the handpiece assembly; and
wherein simultaneous delivery of the first and the second fluids is performed by combining the first and second fluids at a location proximal to the needle.

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.

12. A method of injecting two or more fluids into an anatomy using a handpiece assembly, comprising:
-
moving a needle of a handpiece assembly within an anatomy of a patient, wherein said handpiece assembly comprises a main body and the needle positioned at a distal end of said main body, wherein the handpiece assembly is configured to be selectively grasped and manipulated by a user; wherein the handpiece assembly comprises at least one fluid conduit, said at least one fluid conduit being positioned, at least partially, within an interior of said main body; wherein the handpiece assembly is configured to be in data and fluid communication with a fluid delivery module; wherein at least one of a first fluid and a second fluid is configured to flow from the fluid delivery module to the at least one fluid conduit; wherein the at least one fluid conduit is configured to convey at least one of the first fluid and the second fluid to the needle of the handpiece assembly; wherein the fluid delivery module comprises at least one movable member configured to slide within an interior of at least one fluid reservoir to selectively transfer at least one of the first fluid and the second fluid from the fluid delivery module to the needle; wherein the handpiece assembly is configured such that a flow of fluid proximally through the handpiece assembly, toward the fluid delivery module, is prevented; wherein the main body comprises an electronic control portion, said electronic control portion comprising at least one button configured to control at least one parameter of the delivery of at least one the first fluid and the second fluid through the at least one fluid conduit; wherein the electronic control portion is selectively removable from and attachable to the main body of the handpiece assembly; manipulating the handpiece assembly in order to position the needle into a target anatomical location of the patient; delivering a volume of at least one of the first fluid and the second fluid through the at least one fluid conduit to the needle of the handpiece assembly; and removing the needle from the target anatomical location of the patient once a desired volume of the first and second fluids has been delivered to said target anatomical location. - View Dependent Claims (13, 14, 15, 16, 17, 18)
