Contrast Delivery System

Contrast Delivery System

CVi delivers the power to improve patient safety, minimizing the risk of contrast-induced acute kidney injury (CI-AKI) for coronary catheterizations when compared to manual injection of contrast media.

It’s the contrast injector for:

  • Interventional cardiologists who want to regulate contrast injection flow and minimize risk of CI-AKI—also referred to as contrast induced nephropathy (CIN)
  • Hospital administrators interested in cost containment through cath lab safety and efficiency and reducing potential patient post-procedure adverse events

Stability, Agility and Durability

New transducer arms are now available for ACIST CVi® Contrast Delivery systems

The new design has improved range of motion and is easily lockable in any position. An ergonomic wingnut provides quick and easy adjustment while the solid aluminum construction ensures durability.

Increasing safety and operational efficiency

CVi increases patient and workplace safety, as well as operational efficiency.

Increasing patient safety

Up to 30% reduction in CI-AKI vs. manual injection.

CI-AKI incremental cost range: $13,294 to $14,266.2*

Increasing patient safety

~25% reduction in contrast use without compromising image quality when comparing 4 Fr to 6 Fr diagnostic procedures.3

Bleeding and contrast use were significantly reduced with 5 Fr catheters compared to 6 Fr.4

Increasing workplace safety

Up to 50% reduction in clinician radiation exposure by stepping back.5,6 

Increasing workplace safety

49.4% of interventional cardiologists have experienced at least one orthopedic injury.7 Manual contrast injection may cause repetitive stress injuries to the operator’s hand based on the force required to inject contrast and the number of procedures performed per day.8

Increasing operational efficiency

45 mL decrease per case when injector used.9

There is up to $0.30/mL savings in wasted contrast media.

Increasing operational efficiency

Average 5 min faster per procedure10

Time saved may allow for additional procedures to be performed in a day.10

Improving control, ensuring protection
CVi protects the patient and cath lab team with its innovative variable rate hand controller.
AngioTouch® Hand Controller
The AngioTouch Hand Controller allows real-time, variable-flow control of the contrast injection rate for precise and consistent contrast administration, and clinical data demonstrates up to a 20% reduction in per-patient contrast dosage.
Touch screen monitor
The touch screen monitor provides intuitive on-screen prompts for setup, adjustable injection volume and flow rate limits, contrast tracking information, and real-time readout for continuous system and procedure monitoring.
Air column detection sensor
The built-in air column detection sensor alerts the clinician and stops the injection if air is detected in the single-use patient tubing connected to the catheter.**
Isolated contrast syringe
By providing precise contrast delivery, the multi-patient, isolated contrast syringe with rapid automatic refill can reduce contrast waste and save time between cases.
Hemodynamic monitoring
In-line, hemodynamic monitoring provides a real-time pressure reading, and the automated isolation manifold provides a barrier to the contrast syringe.

    Prior to use, reference Instructions for Use, inside the product carton (when available) or at <> for more detailed information on safe use of the device.
    Indications for Use:
    The ACIST | CVi™ Contrast Delivery System is intended to be used for the controlled infusion of radiopaque contrast media for angiographic procedures.
    The ACIST | CVi™ Contrast Delivery System (CVi system) is not intended for use as a long-term infusion pump. The system is not intended to be used to inject any agents other than contrast media. The system should not be used to inject substances into nonvascular body cavities. Any applications of the system, other than those described in this manual, are inappropriate and should not be attempted. Do not add any components to the consumable kits or in conjunction with the catheter. No valves or other manifolds may be placed in-line between the ACIST-provided consumable kit and the catheter. ACIST-provided consumable kits are designed, manufactured, and tested for connection to catheters used in angiographic procedures. Do not use the system in the presence of flammable gases.
    Important Safety Info:
    The CVi System is designed to aid the physician in the injection of contrast media during angiography. It should be used with adequate radiographic imaging and where monitoring equipment for blood pressure and the electrocardiogram is available. Additionally, standard equipment for cardiopulmonary resuscitation and drugs for the treatment of contrast media-induced drug reactions should be present.It is necessary that the CVi system be operated by, or be under the immediate and direct supervision of a physician who is specifically trained in angiography and in the operation of this unit. System operation must be monitored at all times, and specific operational and mechanical integrity must be maintained to ensure patient safety.
    For proper operation and to ensure equipment compatibility, use only accessories and options provided or specified by ACIST Medical Systems for use with the CVi system. To ensure proper operation of the syringe, viscosity limits must be observed. Do not allow the reusable syringe kit to sit loaded with contrast media longer than the maximum time recommended by the contrast manufacturer. Do not allow the reusable syringe kit to be used for more than five (5) procedures. Replace the automated manifold and hand controller kits after each procedure. Use of the syringe kit for more than five (5) procedures or re-use of the automated manifold and hand controller kits may result in cross contamination, risk of infection or device malfunction, for example, air ingress, leaks, or reduced performance. An air embolism can cause patient injury or death. Operator vigilance and care, along with a defined procedure, are essential to avoid injecting air and causing an air embolism. Before injections, clear all air from the entire patient kit and the angiographic catheter. Make sure that the exterior of the tubing is dry before inserting it into the air column detect sensor. If any fluid is present on the tubing’s exterior surface, the sensor may be unable to detect air. High flow rate injections can cause patient injury or death. Use extreme care when setting the flow rate to avoid unintentionally setting a high flow rate injection. When high flow rate injection is required, be sure to select a pressure setting that does not exceed the rated pressure of the selected catheter.
