10 cm of Lumbar catheter will add, at 10 ml/hr, an extra resistance of 2.4 mmH 2 0 (hydrodynamic
resistance of the Lumbar catheter: 0.024 mmH 2 0 per ml/hr and per cm).
RECOMMENDED IMPLANTATION PROCEDURE
PREPARATION
1. Administer appropriate anesthesia.
2. Place the patient in the lateral position, left side up. Instruct the patient to flex the right (lower) leg and to
extend the left (upper) leg.
3. Prepare and drape the lower back, hip and abdomen.
4. Make an incision above the iliac crest.
PLACEMENT OF THE LUMBAR CATHETER
1. At the physician's option, make a 2 cm incision prior to Tuohy needle insertion.
2. Connect a syringe to the Luer-lock hub of the guidewire dispenser and flush the guidewire with sterile saline
solution.
3. Insert the Luer connector into the catheter. Connect a syringe to the adapter and flush the catheter with sterile
saline solution.
4. Insert the guidewire, PTFE-coated tip first , into the catheter.
5. Insert the Tuohy needle, with obturator in place, into the subarachnoid space. Insert the needle bevel up for
cephalad placement of the catheter; bevel down for caudad placement.
6. To verify that the lumen of the needle has entered subarachnoid space, withdraw the obturator slowly until CSF
appears. If it does not, reinsert the obturator and reposition the needle.
7. Verify that the needle is correctly positioned. Then, remove the obturator and insert the catheter and guidewire
through the needle to the desired lumbar level.
8. Remove the Luer connector and withdraw the needle over the end of the catheter.
Caution: To avoid damage to the catheter, do not withdraw the catheter after it has been inserted into the
needle. If the catheter must be removed, withdraw the needle and catheter simultaneously.
9. Remove the guidewire. Caution: To avoid damage to the catheter, do not withdraw the guidewire without first
removing the Tuohy needle.
10. Anchor the lumbar catheter to fascia using the suture clamp.
11. Using a Tunneler Integra NeuroSciences (Catalog N° 990-001 or 990-010) or other suitable instrument, pass
the lumbar catheter subcutaneously from the back to the previous incision.
12. To remove air from the system, allow CSF to flow through the lumbar catheter. Clamp the catheter.
13. Close the superficial fascia and skin in a routine manner.
14. Trim the free (output) end of the lumbar catheter to the desired length.
Caution: Cut the catheter at its output end only. The input end of the catheter contains drainage holes necessary
for proprer function.
