Lumbar Drainage Catheter Kit
Desu External Lumbar Drainage System
With Antibiotic Impregnated Lumbar Catheter Advanced CSF Management for Infection-Controlled Neurosurgical Procedures
The External Lumbar Drainage System developed by Desu is a precision-engineered, sterile solution for the temporary diversion and controlled management of cerebrospinal fluid (CSF) via the lumbar spine. Designed for clinical environments such as neurosurgical operating rooms, neurological ICUs, and emergency neurology units, this system ensures patient safety, procedural efficiency, and effective CSF regulation.
With the inclusion of a 31 cm antibiotic-impregnated lumbar catheter, supported by an advanced external drainage system, Desu provides a comprehensive toolset for managing elevated intracranial pressure, CSF leaks, or infections related to neurosurgical complications.
System Overview
The Desu External Lumbar Drainage System is supplied as a complete, ready-to-use set. It includes both the catheterization components and the external collection system, eliminating the need for additional assembly or component sourcing.
Antibiotic Impregnated Lumbar Catheter
At the heart of this system is the antibiotic-impregnated lumbar catheter, a 31 cm device specifically designed to minimize the risk of postoperative infection while maintaining the performance required for safe lumbar CSF access.
Key specifications:
Inner Diameter (ID): 0.8 mm
Outer Diameter (OD): 1.6 mm
Length: 31 cm
Material: Barium-impregnated silicone
Drainage Ports: 6 drainage holes, arranged in 4 rows at the proximal end
Radiopacity: High, supported by barium and tantalum marking
The catheter is impregnated with:
Clindamycin Hydrochloride
Rifampicin
These antibiotics are embedded into the catheter wall and released over 28 days, covering the critical postoperative period. This continuous, localized antibiotic delivery greatly reduces the colonization risk of Staphylococcus aureus, Staphylococcus epidermidis, and other common pathogens.
Catheterization Kit Components
The catheterization part of the kit includes the following sterile accessories:
1. Fixation Tab
Ensures external stabilization of the catheter to prevent migration or unintentional removal. It is placed securely at the skin surface to maintain the catheter’s insertion depth and angle.
2. Luer Lock Connector and Distal Cap
Provides a secure and leak-free interface between the catheter and external drainage lines. The Luer lock mechanism allows easy integration into standard CSF collection systems while maintaining a closed system to reduce infection risk.
3. Angled Trocar
Included for cases requiring precise, controlled access to the subarachnoid space. The angled design allows smooth entry, particularly useful in patients with anatomical constraints.
4. 14G Tuohy Needle
A curved-tip spinal access needle widely used in lumbar puncture techniques. It provides the initial access point for catheter insertion with minimal trauma to surrounding tissues.
5. Guidewire
Facilitates the smooth advancement of the catheter during insertion. Its flexible design enhances maneuverability while maintaining directional control, helping avoid complications during placement.
External Drainage System Components
Desu’s system goes beyond standard catheterization by offering a complete CSF drainage circuit, designed for safe fluid collection and pressure regulation:
1. 60 cm Reinforced Cord with Locking Mechanism
Used to suspend the drainage chamber at a fixed height, allowing gravitational drainage and accurate fluid flow control.
2. 30 cm Vertical Measuring Scale
Attached to the system for precise adjustment of CSF pressure. Measurements are clearly marked in both mmHg and cmH₂O, providing clinicians with real-time data and control over intracranial pressure levels.
3. 150 ml Drip Chamber
Collects and displays the initial volume of CSF. Its transparent construction allows for visual inspection of fluid clarity, color, and rate of flow.
4. 800 ml Drainage Bag with Integrated Air Filter
Stores the CSF for analysis or disposal. The air filter ensures sterile conditions within the drainage system and prevents backflow contamination.
5. Three-Way Connectors (x2)
Allows the integration of multiple drainage lines or access points for fluid sampling, administration of intrathecal medications, or circuit flushing.
6. Hydrophobic Filter
Prevents airborne pathogens and moisture from entering the sterile CSF collection pathway. This filter maintains the integrity of the closed system and ensures that no external moisture compromises the sample or line sterility.
Clinical Applications
The Desu External Lumbar Drainage System is suited for a wide range of neurosurgical and neurological conditions, including:
Traumatic brain injury with increased intracranial pressure
Postoperative CSF leakage following spinal or cranial surgery
Subarachnoid hemorrhage requiring pressure reduction
Normal pressure hydrocephalus (NPH)
Pseudotumor cerebri / Idiopathic Intracranial Hypertension (IIH)
Ventriculitis management
Diagnostic CSF sampling when prolonged drainage is required
Its closed, sterile, and pressure-regulated design allows the drainage of CSF while reducing the risk of overdrainage, infection, and pressure fluctuations.
Infection Prevention
A central feature of this system is its infection control strategy. The antibiotic-impregnated catheter, hydrophobic filter, and airtight sealed drainage path work together to create a robust defense against pathogens. This is especially critical in prolonged drainage scenarios or in immunocompromised patients where infection risks are elevated.
The 28-day controlled release of antibiotics addresses bacterial colonization without requiring systemic antibiotics, providing a focused, localized prophylactic effect.
Sterilization and Packaging
All components are individually sterile-packed and suitable for direct use. The complete set is sterilized via ethylene oxide (EtO) and meets international standards for neurosurgical implants and external drainage devices.
