Sterile techniques should be used at all times when handling components of the

AURA™ ICP Monitoring Kit and inserting the AURA™ ICP Sensor.

Placement of the AURA™ ICP Sensor must be carried out by a qualied health

care provider. The health care provider should take appropriate steps and pro-

cedures to avoid infections and complications.

If monitoring is continued for more than 29 days, placement of a new system

under sterile conditions is recommended. The AURATM ICP Sensor must be

explanted from patient after usage or when implantation has reached 29 days.

Usage beyond maximum specied duration may result in patient harm or sys-

tem malfunction.

The AURA™ ICP Sensor and the items included in the AURA™ ICP Monitoring Kit

are designed for SINGLE USE ONLY. DO NOT RESTERILIZE OR REUSE AURA™

ICP Sensor if it has previously been implanted in another patient. DO NOT

REUSE any portions of the kit that have been partially or totally implanted in a

patient. Disposal of parts must be in accordance with hospital policy. Improper

disposal may pose biohazards or environmental hazards.

All Branchpoint Technologies AURA™ components are designed for use with

the AURA™ ICP Monitoring System only. Usage of product outside of specied

indications may result in patient or operator harm.

There are no user serviceable components within the AURA™ ICP Monitoring

System. Any additions or modications to this system, except those supplied or

recommended by Branchpoint Technologies, are prohibited and may interfere

with system performance or result in a hazard or hazardous condition.

Do not subject the AURATM ICP Monitoring Kit components to temperatures out-

side of 0°C to 50°C (32°F to 122°F) storage range. Usage outside of specied

conditions may result in patient harm, packaging damage or system mal-

function. Allow the AURA™ ICP Sensor to reach room temperature before it is

inserted and before “In-Package Check” is performed.

Do not insert the AURA™ ICP Sensor after the “Use by” date on the package

label.

Do not modify, cut, kink, crush, stretch, drop, or otherwise damage any com-

ponent of the AURA™ ICP Sensor. Impairment to the AURA™ ICP Sensor may

result in device malfunction.

The AURA™ ICP Monitoring Kit is provided sterile in sealed packaging.

DO NOT USE if the packaging is wet, punctured, opened, or otherwise dam-

aged. Usage of damaged products may result in a hazard or hazardous condi-

tion. Contact Branchpoint Technologies for instructions to return the AURA™ ICP

Monitoring Kit.

The use of the AURATM ICP Sensor around strong sources of electromagnetism

and electric elds should be avoided.

Compatibility of AURA™ ICP Sensor with magnetic resonance imaging (MRI) has

not been validated.

6. PRECAUTIONS

Patients should avoid devices or medical treatments that generate strong sourc-

es of electromagnetic interference (EMI). EMI may result in device malfunction

or damage.

Patients should avoid medical treatments and diagnostic tests in which an

electrical current is passed through the body, such as TENS, electrocautery,

electrolysis/thermolysis, electromyography, or nerve conduction studies.

Patients should avoid sources of therapeutic ultrasound. Therapeutic ultrasound

may damage the device, however, the damage may not be immediately detect-

able.

Patients with metal implants should not receive medical treatments and diag-

nostic tests using effects caused by electrical elds, such as diathermy.

Patients should avoid sources of ionizing radiation. Ionizing radiation may dam-

age the device, however, the damage may not be immediately detectable.

By design, the AURA™ ICP Sensor emits radio frequency energy in the 2.4

GHz band and is powered by the AURATM Antenna in the 13.56 MHz band. The

presence of other equipment operating in the same frequency bands used by

the AURA™ ICP Sensor may interfere with communication. This interference can

be reduced by increasing the distance between the interfering device and the

AURA™ ICP Sensor.

The AURA™ ICP Sensor shall not be placed in oxygen rich environments.

Cerebral Spinal Fluid leakage, hemorrhage, pain, infection and neurological

damage are potential complications of this procedure. Testing of the blood clot-

ting factor should be conducted on patients before insertion. Decisions regard-

ing the possibility of hemorrhage at the site of placement are the sole responsi-

bility of the practitioner.

7. INSTRUCTIONS FOR USE

INSPECT THE PACKAGING

Visually inspect for mechanical and functional integrity of the packaging and its

contents as well as the legibility and adherence of the AURATM ICP Sensor labels.

If there is evidence of damage or tampering, do NOT use the product and contact
