Abstract

A system allows for collection and re-use of a fluid medium derived from diverting at least some of the fluid medium of an injection. The system comprises a sterile container, an injector, a delivery catheter, a flow diverter assembly and a diversion reservoir assembly. The delivery catheter is in communication with a selected site within a patient'"'"'s body. The flow diverter assembly is disposed in a flow path between the injector and the delivery catheter and is configured to divert at least a portion of a medium of the injection from the flow path. The diversion reservoir assembly has a reservoir chamber fluidly coupled to the flow diverter assembly. The reservoir chamber is configured to receive the diverted portion of the fluid medium to allow re-use by the medium injector of the diverted portion.

Claims

1. A system for collection and re-use of a fluid medium derived from diverting at least some of the fluid medium of an injection of the fluid medium, the system comprising:

a sterile medium container;

a medium injector;

a medium delivery catheter configured to be in communication with a selected site within a patient'"'"'s body;

a flow diverter assembly disposed in a fluid medium flow path between the medium injector and the medium delivery catheter, the flow diverter assembly configured to divert a portion of the fluid medium of the injection from the fluid medium flow path between the medium injector and the medium delivery catheter during injection;

a diversion reservoir assembly having a reservoir chamber fluidly coupled to the flow diverter assembly, wherein the reservoir chamber is configured to receive the diverted portion of the fluid medium from the flow diverter assembly, the diversion reservoir assembly having a fluid coupling to the sterile medium container, wherein the diversion reservoir assembly is configured to allow re-use by the medium injector of the diverted portion of the fluid medium in the reservoir chamber prior to allowing use of the fluid medium in the sterile medium container; and

a medium supply conduit disposed between the flow diverter assembly and the reservoir chamber, wherein the medium supply conduit comprises a check valve to ensure a single direction of medium flow from the flow diverter assembly to the reservoir chamber.
