Abstract
A system for modulating delivery of a fluid medium includes an injector for injecting the fluid medium during an injection cycle, a delivery catheter including a conduit for delivering the fluid medium, a manifold disposed in a fluid medium flow path between the injector and the delivery catheter, and a pulsatile generator. The pulsatile generator is configured to apply a pulsatile force to the fluid medium defined by a plurality of duty cycles during the injection cycle, each of the duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level.
Claims18
A system for modulating delivery of a radiographic contrast medium, the system comprising:
- an injector for injecting the contrast medium during an injection, the injection defined by operative radiographic opacification of a vessel, and the injection having a duration equal to or less than 8 seconds;
- a delivery catheter comprising a conduit for delivering the contrast medium;
- and
- a pulsatile generator configured to apply a pulsatile force to produce pulsation of the contrast medium delivered through the delivery catheter, wherein the pulsatile force is defined by a plurality of duty cycles during the injection, each of the plurality of duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level.
A system for modulating delivery of a fluid medium, the system comprising:
- an injector for injecting the fluid medium during an injection;
- a delivery catheter comprising a conduit for delivering the fluid medium;
- a flow diverter component disposed in a fluid medium flow path between the injector and the delivery catheter, wherein the flow diverter component includes:
- a first medium port fluidly coupled to a fluid reservoir,
- a second medium port fluidly coupled to the injector, and
- a third medium port fluidly coupled to the delivery catheter;
- and
- wherein the flow diverter component is configured, during the injection:
- to direct a first portion of the fluid medium from the injector to the fluid medium flow path and through the delivery catheter conduit, and
- to direct a second diverted portion of the fluid medium from the injector to a diversion reservoir when a threshold pressure level of the fluid medium within the flow diverter component is reached;
- and
- a pulsatile generator configured to apply a pulsatile force to produce pulsation of the fluid medium delivered through the delivery catheter, wherein the pulsatile force is defined by a plurality of duty cycles during the injection, each of the plurality of duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level, wherein the pulsatile generator comprises a movable piston, a solenoid, or a membrane of the diversion reservoir that is configured to act on the second diverted portion of the fluid medium.
A system for modulating delivery of a fluid medium, the system comprising:
- an injector for injecting the fluid medium during an injection cycle;
- a delivery catheter comprising a conduit for delivering the fluid medium;
- and
- a pulsatile generator configured to apply a pulsatile force to produce pulsation of the fluid medium delivered through the delivery catheter, wherein the pulsatile force is defined by a plurality of duty cycles during the injection cycle, each of the plurality of duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level;
- and
- a valve that comprises:
- a diverter arm;
- a valve housing attached to the diverter arm, wherein the valve housing and the diverter arm define an internal chamber therein;
- and
- a diffuser movably received within the internal chamber.
