standard surgical procedure and skill.
Hemorrhage from the dura or cortical surface
at the bolt insertion site may occur.
Patients should be tested for normal blood
clotting function prior to bolt placement.
Determination of
subarachnoid, or intracerebral hemorrhage at
the bolt insertion site will be the responsibility
solely of the
Appropriate steps and proceedings to control
such hemorrhage should be taken when
indicated by the neurosurgeon in charge.
PRECAUTIONS
• Extreme bending and/or kinks can impair
the performance of the Fiber Optic Pressure
Transducer. Exercise caution when handling
the catheter.
• The catheter is designed for SINGLE USE
ONLY. DO NOT RESTERILIZE OR REUSE.
Camino 110-4BT is supplied in a single use
package and is guaranteed to be sterile and
non-pyrogenic unless opened or damaged.
The catheter design incorporates a small
lumen and intricate sensors that are likely
to make it difficult to assure removal of all
contamination. Additionally, reprocessing is
likely to damage one or more of the delicate
sensors that may result in impaired function
(e.g. no or inaccurate measurements).
• Use aseptic
procedures.
• Maintain the insertion site with regular
meticulous redressing
technique.
• Do not attach anything to transducer air vent.
Vent must remain open for proper operation
(Figure 1).
CAUTION
• Federal (U.S.A.) law restricts this device to
sale by or on the order of a physician.
• Connect the thermistor connector only to
Host Monitors marked "Patient connection
electrically isolated", or "BF" or "CF", or
marked with the international symbols:
• When connecting the thermistor connector
to a Host Monitor, refer to the Host Monitor's
operations manual for complete instructions.
• Verify proper operation of the combined Host
Monitor–110-4BT System before clinical use.
• The combined leakage currents of devices
interconnected with the 110-4BT can lead

his head rotated from side to side and still
remain in a supine position without interference
with the monitoring function.
In addition, the incision will be carried behind
the hairline in the majority of patients and
therefore be cosmetically acceptable.
After the insertion site has been chosen,
the area is shaved and prepped in a sterile
fashion, usually with a Betadine
aseptic
shaved and prepared area is then draped with
sterile towels. The area of the incision, which
usually lies two to three centimeters anterior to
the coronal suture in the mid-pupillary line is
infiltrated subcutaneously with 1% Xylocaine
An approximately half centimeter linear incision
is made and carried to the bone. A small
mastoid type of retractor is then inserted to
provide a good bone exposure and hemostasis
of the skin edges.
The safety stop on the drill bit provided in the kit
can be positioned as desired by loosening the
setscrew with the hex wrench, sliding the stop
into position, and retightening the setscrew.
The drill bit is then secured to a twist drill
and in a standard fashion, a twist drill hole is
made through the outer and inner tables of the
skull. The surgeon needs to be careful when
penetrating the inner table to minimize any
potential for parenchymal injury.
After penetration of the inner table, the drill is
removed and the hole is irrigated with sterile
