Close the clamp below the atmospheric vent on the collection bag to prevent
wetting the vent when the bag is laid down, such as during patient transport.
If the vent becomes wet, it may prevent the flow of CSF into the bag. Once
the system is set up on an IV pole or other support, open the clamp below
the vent.
Be aware that the clamp on the tubing below the atmospheric vent of the
bag must be open to facilitate CSF flow into the collection bag.
Precautions for EDS 3 Leveling Device
Do not stare into the laser beam.
Laser light, when reflected from a mirror-like surface, can be dangerous.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
Sterility
The CODMAN EDS 3 CSF External Drainage System is intended for SINGLE
USE ONLY; DO NOT RESTERILIZE. Use aseptic technique in all phases of
handling. Codman Single Use devices have not been designed to undergo
or withstand any form of alteration, such as disassembly, cleaning or
re-sterilization, 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 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 inner unit is not opened or damaged, the product is sterile.
The following components have been tested and were determined to
be nonpyrogenic:
Drainage Tubing fluid pathway from injection site to male
LUER-LOK Connector
Catheter
Catheter LUER-LOK
INSTRUCTIONS FOR USE
General Surgical Technique: Ventricular Catheter
Since the sites of insertion of the ventricular catheter vary, decisions
regarding the technique of insertion and verification of proper placement
must be made by the surgeon on a case-by-case basis.
1. Aseptically prepare and drape the operative site.
2. Perform the craniotomy.
3. Perform the catheterization with the stylet inserted in the catheter.
4. Remove the stylet, and check for free flow of fluid. If using the CODMAN
EDS 3 Clear Ventricular CSF Catheter (82-1735) the depth of insertion
can be verified using the scale printed on the catheter.
5. Insert the barbed end of the trocar into the distal end of the
catheter. Insert the sharp end of the trocar into the skin and tunnel
subcutaneously for a short distance. See Figure 2.
Bring the trocar out through the scalp. Taking care not to dislodge
the implanted portion of the catheter, draw the catheter through the
subcutaneous tunnel until the loop of the catheter no longer protrudes
from the incision. See Figure 3.
6. Occlude the catheter with rubber shod forceps and remove the trocar
from the catheter.
CAUTION: Silicone tears and cuts easily. Use rubber shod forceps when
handling silicone catheters.
7. Insert the barbed end of the female LUER-LOK connector (with cap
attached) into the end of the catheter. Suture the components together.
Do not remove the LUER-LOK cap until ready to attach the catheter to
the patient line of the drainage system.
CAUTION: It is recommended that the catheter be sutured to the
LUER-LOK connector to prevent possible separation of the components
when the catheter is removed.
Exercise care when placing ligatures to avoid cutting or occluding
the tubing. The use of stainless steel ligatures on silicone products is
not recommended.
8. Secure the catheter to the skin at the exit site. Suture the incision site.
Cover the area with a sterile dressing.
General Surgical Technique: Lumbar Catheter
Refer to the instructions packaged with the lumbar catheter for
placement procedures.
Installing the EDS 3 CSF External Drainage system
Installing the EDS 3 system comprises the following:
• M ounting the EDS 3 device to an I.V. pole.
• L eveling the EDS 3 device in relationship to the floor.
• L eveling the EDS 3 device in relationship to the patient.
• P ositioning the Drip Chamber.
• P riming the EDS 3 unit.
• C onnecting the EDS 3 device to the patient catheter.
Mounting the EDS 3 device to an I.V. pole
1. Remove the product from its packaging.
2. Secure the EDS 3 device to an I.V. pole by fitting the clamp over the pole
and securing it in place by tightening the blue screw (see Figure 4).
3. Place the cord that is attached to the EDS 3 device over the I.V. pole
and secure it in place by pressing the button on the locking mechanism
and sliding the mechanism until it is tight against the pole. Knot the cord
above the locking mechanism after placement.
Leveling the EDS 3 device in Relationship to the Floor
1. Remove the twist tie from the CODMAN EDS 3 Leveling Device.
2. Attach the CODMAN EDS 3 Leveling Device to the unit by sliding the
securing tab over the slot on the EDS 3 (see Figure 5).
Note: Point the laser towards the patient.
3. Level the unit on the I.V. pole (see Figure 6):
a. Loosen the gray screw and rotate the assembly to the point where
it is level to the floor (bubble is centered in glass tube).
b. Once it is level, secure the EDS 3 system into position using the
gray screw.
4. Proceed to Leveling the EDS 3 device in Relationship to the Patient.
Leveling the EDS 3 device in Relationship to the Patient
1. Secure the CODMAN EDS 3 Leveling Device to the EDS 3 system,
pointing the laser on the leveling device toward the patient.
2. Level the unit on the I.V. pole as follows:
a. Rotate the laser pointer until the laser emits from the pointer
(see Figure 7).
b. Direct the laser towards the patient.
c. Loosen the blue screw and adjust the height of the EDS 3 unit (see
Figure 8a) centering the laser pointer to the patient's external auditory
meatus for ventricular drainage or to the lumbar catheter exit site
for lumbar drainage. This represents the "Zero" reference point (see
Figure 8b).
d. Rotate the laser pointer until the laser is extinguished.
3. Remove the leveling device from the EDS 3 unit.
Positioning the Drip Chamber
WARNING: Intracranial pressure is controlled by the height of the
Drip Chamber relative to the patient. It is imperative that neither the
Drip Chamber nor the patient be raised or lowered accidentally.
Movement by the patient after positioning of the Drip Chamber may
affect the patient's ICP.
Close the two clamps at the top of the collection bag if it is necessary
to invert the EDS 3 unit. This will prevent liquid from wetting the vent at
the top of the bag, which will prevent proper drainage, and will prevent
liquid from refluxing to the drip chamber.
