Desu External Ventricular Drainage System with Antibiotic-Impregnated Ventricular Catheter

Advanced Cerebrospinal Fluid Management for Critical Neurological Care

In the management of elevated intracranial pressure and cerebrospinal fluid (CSF) disorders, precision, sterility, and rapid deployment are non-negotiable. Neurological emergencies such as subarachnoid hemorrhage, hydrocephalus, or traumatic brain injury often require immediate and controlled CSF diversion. The Desu ENDS-AC-020 Advanced External Ventricular Drainage System is engineered to meet these exacting demands. Designed for acute neurocritical care, this system offers clinicians a comprehensive, safe, and easy-to-use platform for external CSF drainage and pressure monitoring.

At the heart of this system lies an antibiotic-impregnated ventricular catheter that helps protect against one of the most serious risks in neurosurgery: infection. Complemented by a complete drainage and monitoring assembly, Desu’s ENDS-AC-020 represents a gold standard in temporary CSF management.

Infection Prevention Through Antibiotic Impregnation

The antibiotic-impregnated ventricular catheter is the defining feature of the ENDS-AC-020. Made from biocompatible materials and infused with antimicrobial agents, the catheter is specifically designed to reduce catheter-related infections. This is critical, as external CSF drainage systems—by nature—create an open pathway into the central nervous system, which can serve as a direct route for pathogens.

Desu’s catheter delivers controlled antibiotic release over a 28-day period, providing extended protection against bacterial colonization. This slow-release mechanism ensures that therapeutic levels of the antibiotic are maintained at the catheter-tissue interface, preventing the development of biofilms and reducing the risk of ventriculitis or meningitis. For neurocritical care teams, this added level of safety can significantly lower ICU stay durations, reduce complications, and improve patient outcomes.

With a length of 80 cm, an inner diameter (ID) of 1.5 mm, and an outer diameter (OD) of 3.0 mm, the catheter balances flexibility with stability. Its length allows for versatile routing during placement, whether tunneled or directly fixed. The material resists kinking, supports smooth CSF flow, and provides sufficient radiopacity for image-guided positioning.

Complete Drainage System for Real-Time Monitoring

The ENDS-AC-020 isn’t just a catheter—it’s a fully integrated system for precise CSF drainage and pressure measurement. It includes every component necessary for setup and use in intensive care units, operating rooms, or emergency settings.

The drainage system begins with a 60 cm reinforced cord that includes an integrated locking mechanism. This cord is used to stabilize the entire assembly when suspended from IV poles or bedside structures. The lock prevents unintentional movement, which could otherwise lead to inaccurate pressure readings or inconsistent drainage.

Attached to the system is a 30 cm measurement scale calibrated in both mmHg and cmH₂O, which allows for real-time monitoring of intracranial pressure. Proper alignment of the drip chamber and measurement scale is essential for accurate CSF flow control, and Desu’s precise markings make pressure adjustments intuitive and reliable.

The 150 ml drip chamber provides clinicians with a clear, real-time view of CSF outflow. This component is particularly important for observing the presence of blood, debris, or color changes—clinical indicators that could suggest complications such as infection, hemorrhage, or catheter blockage.

CSF is collected in an 800 ml drainage bag, which includes an integrated air filter to maintain a sterile, closed-loop system. The large capacity of the bag makes it suitable for extended monitoring without frequent emptying, reducing handling and contamination risk.

To further enhance flexibility, the system features two three-way connectors, which enable easy access for CSF sampling, drug administration, or drainage redirection. The inclusion of a hydrophobic filter adds another layer of protection by preventing moisture and microorganisms from entering the sterile drainage path.

Ergonomic and User-Centered Design

Desu has prioritized usability in every detail of the ENDS-AC-020 system. The catheter fixation tab secures the device at the cranial exit point, preventing accidental dislodgement while allowing for controlled head movement. This feature is especially critical in sedated or ventilated patients where mobility is limited but still present.

A Luer lock connector and distal cap are included with the catheter, providing a secure connection and sealed closure for periods when the system is disconnected. This maintains sterility and allows for safe transitions during transport or device exchanges.

Insertion is facilitated by a specially designed angled trocar, which offers an ideal trajectory for ventricular access with minimal trauma to surrounding tissue. Accompanying the trocar is a stylet, which supports the catheter during placement, ensuring directional accuracy and improved control in delicate cranial procedures.

Each component is delivered in sterile packaging, designed for single use. The materials used are DEHP-free, latex-free, and fully biocompatible, ensuring patient safety and regulatory compliance in global healthcare systems.

Applications in Neurocritical Care

The Desu ENDS-AC-020 system is used in a wide variety of acute and chronic neurosurgical conditions that require temporary external CSF diversion. These include, but are not limited to:

Acute hydrocephalus (traumatic, obstructive, or communicating)

Subarachnoid hemorrhage (SAH) with elevated ICP

Intraventricular hemorrhage requiring pressure relief

Post-operative drainage following tumor resection or shunt revision

Intracranial pressure monitoring for diagnostic evaluation

Infections requiring external drainage and antibiotic therapy

In each of these applications, the system’s ability to balance CSF output, prevent infection, and facilitate pressure monitoring plays a vital role in clinical decision-making and patient stabilization.

Designed for Efficiency, Built for Trust

The ENDS-AC-020 Series is engineered with real-world hospital workflows in mind. Its all-in-one packaging minimizes setup time, while the intuitive layout reduces the potential for error during assembly. With every component included—catheter, connectors, measurement scale, and collection system—healthcare teams can act fast and focus on treatment, not logistics.

The system is compatible with standard ICU equipment and does not require specialized racks or proprietary mounts. Whether in a tertiary care hospital, trauma center, or emergency operating theater, Desu’s EVD system adapts seamlessly to its clinical environment.

Furthermore, Desu provides complete usage guidelines and procedural videos to train staff on the correct assembly and operation of the ENDS-AC-020. By supporting clinicians from first use to follow-up, Desu enhances procedural consistency and safety.

Long-Term Value Through Reduced Complications

Infection is a primary concern with any external CSF drainage device. By incorporating an antibiotic-impregnated catheter that actively defends against microbial invasion, Desu’s ENDS-AC-020 helps reduce one of the most costly and dangerous risks in neurocritical care. The 28-day antibiotic release mechanism significantly reduces the chances of catheter-associated infections, lowering the need for additional antibiotic therapy, patient isolation, and ICU stays.

Beyond infection control, the system also reduces costs through its reliable performance, durability, and low complication rate. With fewer occlusions, reduced need for repositioning, and enhanced monitoring, hospitals benefit from greater procedural efficiency and reduced overall treatment costs.

The Desu ENDS-AC-020 Advanced External Ventricular Drainage System is a comprehensive, clinically refined solution for the management of intracranial pressure and cerebrospinal fluid drainage. With its antibiotic-impregnated catheter, precision monitoring tools, and intuitive layout, it empowers healthcare providers to deliver high-quality neurocritical care with speed, safety, and confidence.

By addressing the most critical concerns—namely infection risk, fluid control, and usability—Desu ensures that every moment of treatment is supported by cutting-edge medical engineering. Whether you are treating life-threatening hydrocephalus or conducting post-operative ICP monitoring, the ENDS-AC-020 provides the control you need to act decisively.
