until the tip can be seen through the first hole at the
distal end of the catheter as shown in Figure 8.
7. Reattach the white female LUER-LOK connector
and Tuohy-Borst adapter to the ventricular catheter
as shown in Figure 9. Finger-tighten all LUER-LOK
connections.
8. Firmly tighten the Tuohy-Borst adapter cap
(turn clockwise), verifying that the transducer tip
remains in position as shown in Figure 8. Readjust
if necessary.
9. Introduce the ventricular catheter into the
ventricle as described in the General Surgical
Procedure section.
Electrostatic Discharge (ESD) Information
Exposure to electrostatic discharge (ESD) energy
could damage this device. High levels of ESD could
damage the electronic components and cause the
transducer to be rendered inaccurate or inoperable.
Take all precautions to reduce the buildup of
electrostatic charge during the use of this product.
• Provide patient grounding, e.g., grounding
straps on gurneys.
• Avoid the use of materials that could generate
ESD during patient movement and transport,
e.g., nylon transfer boards with bedding.
• Before touching the patient, caretakers should
discharge ESD buildup by touching a grounded
metal surface, such as a bed rail.
It is recommended that all hospital personnel in
contact with these devices receive an explanation of
ESD and training in ESD precautionary procedures.
Training should include, at a minimum, an introduction
to electrostatic discharge, when and why it occurs,
precautionary measures, and the damage that can be
done to electronic components if touched by a user
who is electrostatically charged.
Avoid touching the connector pins before following
ESD precautionary procedures. Avoid touching the
transducer tip (sensing element) at all times.
Sterilization
The CODMAN MICROSENSOR Ventricular Catheter
Kit is intended for SINGLE USE ONLY; DO NOT
RESTERlLlZE. Codman Single-Use devices have
not been designed to undergo or withstand any
form of alteration, such as disassembly, cleaning or
resterilization, after a single patient use. These devices
are intended to come into contact with the central
nervous system and the ability does not currently exist
to destroy possible contaminates such as Creutzfeldt-
Jakob Disease. Reuse can also compromise device
performance and any usage beyond the design intent
of this single-use device can result in unpredictable
use hazards or loss of functionality.
Codman & Shurtleff, Inc. will not be responsible for
any product that is resterilized, nor accept for credit
or exchange any product that has been opened but
not used.
As long as the individual package of the CODMAN
MICROSENSOR Ventricular Catheter Kit is not
damaged or opened, the product is sterile.
All components, except the electrical sensor,
have been tested and were determined to be
nonpyrogenic.
