CODMAN MICROSENSOR
Basic Kit
Description
The CODMAN MICROSENSOR
number 82-6631, consists of the CODMAN
MICROSENSOR ICP Transducer and a 14-gauge
Tuohy needle, as shown in Figure 1.
The CODMAN MICROSENSOR ICP Transducer is a
catheter with a microminiature silicon strain gauge
type sensor mounted at one end and an electrical
connector at the other end. It is designed for
use with the CODMAN
catalog numbers 82-6634 (117 VAC) and 82-6635
(230 VAC). In conjunction with the ICP EXPRESS
Monitor, the MICROSENSOR
to a wide variety of patient monitoring systems for
ICP waveform display, or for consolidation of ICP
data with other vital signs information.
The CODMAN MICROSENSOR Basic Kit is
designed for use with the CODMAN Cranial Hand
Drill, catalog number 82-6607. The drill facilitates
access to the intraparenchymal area.
Indications
Use of the CODMAN MICROSENSOR Basic Kit
is indicated when direct intracranial pressure (ICP)
monitoring is required. The kit is indicated for use
in both subdural and intraparenchymal pressure
monitoring applications only.
Contraindications
This device is not designed, sold, or intended
for any use except as indicated.
This device is not designed, sold, or intended
for use as a therapeutic device.
Compatibility of implantable catheter-tipped
pressure transducers with magnetic resonance
imaging (MRI) has not been determined.

WARNINGS
The use of electrosurgical equipment (e.g.,
Monopolar, Bipolar, Diathermy) can cause
damage to the ICP MICROSENSOR and/or ICP
EXPRESS Monitor. This could lead to permanent
or temporary disabling of either device.
Precautions
Inspect the sterile package carefully. Do not use if:
• the package or seal appears damaged,
• contents appear damaged, or
• the expiry date has passed.
It is essential to maintain strict sterile technique
during transducer placement. All procedures should
be performed by a qualified neurosurgeon using
standard surgical procedure. The neurosurgeon
is responsible for taking appropriate steps and
procedures to avoid infections and complications.
The transducer can break if exposed to pressures
over 1250 mm Hg (166650 Pa).
Do not strongly pull or jerk the catheter.
The MICROSENSOR must be zeroed at
atmospheric pressure prior to implantation.
The transducer element is light sensitive and
should be shielded from direct light sources during
zeroing and usage.
Take care when tying sutures onto the sensor.
Tying sutures too tightly can collapse the wall of
the sensor body, causing damage to internal wires.
Do not expose ICP transducer to solvents or
cleaning agents, including alcohol; these may
cause inaccurate ICP measurements.
Avoid direct contact with the sensing element
of the transducer.
To ensure accurate ICP measurements, position
the sensing element of the transducer tip towards
the cortex during subdural pressure monitoring.
Read all instructions included with the
ICP EXPRESS Monitor prior to use.
Use CODMAN Patient Monitor Interface Cables
only with the patient monitors for which they are
specifically designed and designated.
Do not submerge the tip of the transducer
or catheter vertically in a deep pool or cup
of sterile water/sterile saline. Doing so will
impose a hydrostatic pressure on the transducer
diaphragm that is higher than atmospheric zero,
resulting in an inaccurate zero reference.
