ensure proper understanding and use. Operate the device only in accordance
with this user guide to ensure safe and eective use.
Upon arrival, inspect all packaging and the delivered items for signs of damage
that may have occurred during transportation. If any item appears damaged,
contact an ACIST service representative.
e following warnings refer to hazards that can cause serious injury or death.
Please read and understand all the following warnings before proceeding with
installation, setup, and operation of the CVi system.
Aseptic Technique
Contamination of patient kits or the contrast container septum presents a risk
of serious patient injury due to infection. Aseptic technique must be employed.
If suspected contamination has occurred, replace the aected item.
Air Embolism
An air embolism can cause patient injury or death. Operator vigilance and
care, along with a dened 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 uid is present
on the tubing's exterior surface, the sensor may be unable to detect air.
Air in the Monitoring Line
Clear the monitoring line of all air to avoid producing an inaccurate blood
pressure reading.
Air Column Detect Mechanism
e CVi system is equipped with an air column detect sensor. e air column
detect sensor cannot detect air in the patient catheter, the stopcock, or the
patient tubing past the sensor. is sensor is designed to aid the user in the
detection of air columns in the injection tubing, but it is not designed to
replace the vigilance and care required of the operator in visually inspecting
for air and clearing air from the entire patient kit and angiographic catheter.
e air column detect mechanism is to be used in conjunction with and to
complement the user's other procedures for preventing air injections.

Disconnect Before Flushing Air
When ushing air, be sure the tubing is disconnected from the patient.
Use of Patient Kits
ACIST-provided patient kits are designed, manufactured, and tested for
connection to catheters used in angiographic procedures. Failure to observe the
following guidelines can result in patient injury or equipment damage:
• Do not add any components to the patient kits or in conjunction with the
catheter.
• No valves or other manifolds may be placed inline between the patient kit
and the catheter.
• Do not use the single use kits on more than one patient.
• Do not allow any patient kit loaded with ISOVUE (iopamidol injection)
contrast media to sit unused for more than 10 hours.
• Do not use a syringe kit for more than six cases.
• Dispose of all single use components, including the saline bag, Manifold Kit,
and AngioTouch Hand Controller Kit aer every case.
• Properly discard patient kits in accordance with all local, state, and federal
regulations, codes, and directives.
Cables
Be sure to plug each cable only into the connector designed for it. To avoid the
risk of electric shock, never touch the pins on the connector or cable. Do not
use the CVi system if any worn or damaged cords, cables, or connectors are
detected. For replacement information, contact an ACIST representative.
Catheters
Patient connections must be made using commercially available catheters that
have been approved for angiographic studies. e system pressure limit should
not be set higher than the rated pressure limit of the catheter. For information
on catheter pressure settings and limits, refer to the instructions provided by
the catheter manufacturer.
e CVi system was tested for use with 4Fr–7Fr catheter sizes. When using
catheters 5Fr or smaller with injection ow rates >12ml/s, the system may
reduce the ow rate to prevent Pressure Limit while providing selected volume,
or the system may Pressure Limit and stop the injection. To obtain the desired
imaging outcome in the event of Pressure Limit, the user must either reduce
the selected ow rate or use a larger size catheter to complete the injection.
Cleaning
• To avoid the risk of electric shock, and to prevent damage to the CVi
system, always disconnect it from line power before cleaning.
• Do not use excessive water when cleaning.
• A disinfecting cap must be properly placed onto the multi-use syringe
before cleaning.

select a pressure setting that does not exceed the catheter's pressure rating. e
maximum pressure rating of the CVi system is 1200 psi.
Injection System Setting
Check the CVi system settings before injection, and verify the appropriateness
of all injection parameters before injecting.
Mounting System
e use of non-approved mounting equipment can cause injury. Mount the
CVi system using only mounting assemblies approved by ACIST Medical
Systems.
Residual Contrast
Performing a saline ush following injection of contrast media will
dispense residual contrast from the patient line to the patient. If it is
suspected that such residue may adversely aect the patient, additional
injections of contrast or saline should not be performed.
Shock Hazard
Hazardous voltage exists within the CVi system. To avoid the risk of electric
shock, only trained, qualied personnel should service the CVi system.

e CVi system is an angiographic injection system used in interventional
cardiology, radiology, or vascular surgical procedures utilizing an endovascular
technique. e CVi system supplies radiopaque contrast media to a catheter
at a user-determined variable ow rate that can be instantaneously and
continuously varied.
e CVi system contains a motor-driven pump that delivers contrast media
to a patient catheter. e ow rate of contrast media from the injector to
the catheter can be controlled with a user actuated proportional control: the
AngioTouch® Hand Controller. e hand controller allows variable rate or xed
rate control when dispensing contrast media. When using the variable rate
feature, the CVi system allows the user to vary the ow rate from the injector
while simultaneously observing the angiographic procedure (for example, on a
uoroscope monitor).
e hand controller and other components are provided in angiographic
patient kits. e patient kits provide the interface between the CVi system and
an angiographic patient catheter (not supplied by ACIST).
If desired, blood pressure may be monitored through the system in conjunction
with the lab's monitoring equipment.
e CVi system is able to synchronize with certain X-ray imaging systems.
See Supported Imaging Systems on page 85 for additional information.
Synchronization is only possible provided the proper X-ray interface cable is
also purchased and installed.
