The Medtronic Duet™ External Drainage and Monitoring System (Duet™ EDMS) is a complete draining and monitoring cerebrospinal system for externally fluid (CSF) and monitoring intracranial pressure (ICP). It can be used for both external ventricular and lumbar drainage. The Duet™ EDMS is an external drainage and monitoring system that uses gravity to drain cerebrospinal fluid (CSF) from the patient's ventricles or lumbar space to an external drainage receptacle. The drainage flow of CSF into the Duet™ EDMS is uni-directional and gravity-driven; there is no recirculation of the CSF. The Duet's catheter is surgically attached to the patient before it is attached to the drainage system. An opening is made in the patient's skull lumbar region and a catheter is inserted into patient's ventricle or the lumbar or subarachnoid space. The catheter is then attached to the drainage system. The CSF or blood is drained and monitored until the patient is stabilized, the infection successfully treated, or a long-term drainage method is implemented.

The XABO Catheters are used for cerebrospinal fluid (CSF) shunting.

The XABO Catheters are manufactured using barium sulfate fillcone elastomer and are impregnated with clindamycin hydrochloride and rifampicin designed to be released over time from the exterior and inner lumen surface once implanted. The XABO Ventricular Catheters will be offered in 18 cm in length with an inner diameter of 1.2 mm and an outer diameter of 2.5 mm. Lengths are marked in 1 cm intervals starting from the catheter tip, thus enabling the surgeon to qauge the depth of penetration of the catheter into the lateral ventricle. The proximal end of the catheter has 16 flow holes around the catheter circumference. Components supplied with the XABO Ventricular Catheter include a pre-loaded stainless steel stylet and depending on the confiquration may contain a deflector. The XABO Peritoneal Catheters measure 60 cm or 120 cm in length, 1.2 mm in inner diameter, and 2.5 mm in outer diameter. There are no length markers or wall slits on the tip is open ended.

The Bactiseal Catheters are indicated for use in the treatment of hydrocephalus as a component of a shunt system when draining or shunting of cerebrospinal fluid (CSF) is indicated. The Bactiseal Barium Striped Catheters are indicated for use in the treatment of hydrocephalus as a component of a shunt system when draining of cerebrospinal fluid (CSF) is indicated. The Bactiseal Endoscopic Ventricular Catheter is designed for use in the treatment of hydrocephalus when shunting cerebrospinal fluid (CSF) from the ventricles of the brain.

The Bactiseal Catheters, Bactiseal Barium Striped Catheters and Bactiseal Endoscopic Ventricular Catheter include a ventricular and/or distal (peritoneal) drainage catheter that are used as part of a CSF shunting system to treat hydrocephalus. Both catheters are attached to the valve portion of a shunting system, which is then implanted in the patient's brain. The ventricular catheter diverts the excessive CSF from the ventricles of the brain through the valve. After passing through the valve, the excessive CSF is drained through the distal (peritoneal) drainage catheter into another part of the body, such as the peritoneal cavity, where it is reabsorbed into the bloodstream. The catheters are subjected to a treatment process by which the silicone is impregnated with two antimicrobials, rifampicin and clindamycin hydrochloride. Bactiseal silicone catheters have been shown in laboratory studies to reduce the colonization of gram-positive bacteria on the tubing surface. The catheters contain barium sulfate for radiopacity and have tantalum "dots" incorporated onto the silicone tubing to aid in positioning of the catheter. The Bactiseal Catheters and Bactiseal Endoscopic Ventricular Catheter are made of radiopaque silicone tubing, and the Bactiseal Barium Striped Catheters are made of clear silicone tubing with radiopaque striping. The Bactiseal Endoscopic Ventricular Catheter has a slit in the tip of the ventricular catheter in order for the catheter to be placed with the use of an endoscope.

The Bactiseal EVD Catheter and Bactiseal Clear EVD Catheter sets are indicated for gaining access to the ventricles of the brain and can be used with dimensionally compatible devices for draining cerebrospinal fluid (CSF) and other fluids of similar physical characteristics as a means of reducing intracranial pressure and CSF volume.

The Bactiseal EVD Catheter Sets and Bactiseal Clear EVD Catheter Set include a ventricular catheter that is supplied with component accessories that facilitate placement and use of the catheter for reducing and controlling intracranial pressure due to excess cerebrospinal fluid. The ventricular catheter is subjected to a treatment process by which the silicone is impregnated with two antimicrobials, rifampicin and clindamycin hydrochloride. Laboratory studies show Bactiseal treated catheters reduce the colonization of gram-positive bacteria on the tubing surface. The ventricular catheter is placed in the ventricles of the brain and CSF enters the fluid conduit through the inlet holes near the tip of the catheter and drains into the external drainage system connected to the catheter. The catheter contains barium sulfate for radiopacity and includes numerical depth markings and circumferential bands, made of ink, from the proximal tip.

The use of IRRAflow Active Fluid Exchange System is intracranial pressure monitoring is required, and for externally draining intracranial fluid, as a means of reducing intracranial pressure in patients where an external drainage and monitoring system is needed.

The IRRAflow® Active Fluid Exchange System (AFES) is an intracranial pressure (ICP) monitoring and drainage system intended for use by professional medical hospital personnel, trained and experienced in neurosurgical medical care. The drainage flow of cerebrospinal fluid (CSF) into the IRRAflow Catheter is uni-directional and gravity-driven; there is no recirculation of the CSF. A parallel line from the saline infusion bag is used in case clearance at the tip of the catheter is required. The IRRAflow Tube Set has a cassette that clicks on to the IRRAflow Control Unit and aligns the tubing against a peristaltic pump and pinch valve. The IRRAflow Drainage Collection System is attached to the Control Unit, using the Laser Leveler for defining the height of the Drainage Collection System relative to the catheter's tip position in the patient's head. This positioning is used for controlling the speed of drainage. The tubing and catheter can be disconnected and connected by standard Luer-Lock connectors. Settings can be changed via the user interface on the Control Unit. The default mode provides drainage and measuring ICP, allowing bolus injections when indicated. The bolus injections allow the catheter to be flushed when it becomes clogged. CSF or intracranial fluid samples can be taken from the Drainage Collection System.
