DESU® Catheter systems are used as a component of shunt systems indicated for use to drain or shunt the cerebrospinal fluid (CSF) in treatment of hydrocephalus. All DESU Catheters are manufactured with barium impregnated silicone raw material to allow radiopacity. In addition, tantalum is used to mark the length measurements on the catheters, which allows visibility during magnetic resonance imaging (MRI).
Antibiotic impregnated catheters (barium impregnated) are manufactured using long-term implantable grade silicone tubing. The catheters, which are impregnated with Rifampicin and Clindamycin HCl, are shown to decrease gram-positive bacteria colonization.
Length and Inner and Outer Diameter Measurements of the Catheters
| CATHETER TYPE | LENGTH (CM) | İNNER DIAMETER / OUTER DIAMETER (MM) |
|---|---|---|
| VENTRICULAR CATHETER | 23 | 1.3 / 2.5 |
| PERITONEAL CATHETER | 120 | 1.1/ 1.3 |
| EXTERNAL VENTRICULAR CATHETER | 31 | 1.5 / 3 |
| EXTERNAL LUMBAR CATHETER | 80 | 0.8 / 1.6 |
| LUMBAR CATHETER | 105 | 0.8 / 1.6 |
A) VENTRICULAR CATHETER (STANDARD / ANTIBIOTIC)
Ventricular catheter is used to transfer excess CSF (cerebrospinal fluid) from the brain ventricles to the shunt. Ventricular catheter length is 23 cm. Inner diameter of the catheter is 1.3 mm and outer diameter is 2.5 mm. Tantalum is used to mark the length measurements on the catheters on 5, 10 and 15 cm points.
B) PERITONEAL CATHETER (STANDARD / ANTIBIOTIC IMPREGNATED)
Peritoneal catheter is used to transfer excess CSF, that is drained with a controlled pressure from the ventricles by the use of ventriculoperitoneal shunt.
Peritoneal catheter length is 120 cm. Inner diameter of the catheter is 1.1 mm and outer diameter is 1.3 mm. Tantalum is used to mark the length measurements on the catheters on 5, 10,15 and 20 cm points.
C) VENTRICULOPERITONEAL CATHETER KIT (STANDARD / ANTIBIOTIC IMPREGNATED)
| Standard Ventriculoperitoneal Catheter Kit | Antibiotic Impregnated Ventriculoperitoneal Catheter Kit |
|---|---|
| Barium impregnated radiopaque silicone material Magnetic Resonance Imaging (MRI) visibility through the use of tantalum markings 24 entry holes at the proximal tip to avoid obstruction | Barium impregnated radiopaque silicone material Magnetic Resonance Imaging (MRI) visibility through the use of tantalum markings 24 entry holes at the proximal tip to avoid obstruction Antibacterial protection for 28 days, through impregnation of Rifampicin and Clindamycin HCl. Colonization and obstruction preventing inner and outer surface through hydrophilic characteristic (0.054%) Rifampicin and (0.15%) Clidamycin HCl content Antibiotic dose suitable for pediatric use |
D) EXTERNAL VENTRICULAR DRAINAGE CATHETER KIT (STANDARD / ANTIBIOTIC IMPREGNATED)
External Ventricular Drainage Catheter is the main component of the External Neurological Drainage System and is used to drain excess CSF from the brain ventricles and transfer it to the drainage system.
E) EXTERNAL LUMBAR DRAINAGE CATHETER
External Lumbar Drainage Catheter is the main component of the External Neurological Drainage System and is used to drain excess CSF from the lumbar subarachnoid cavity and transfer it to the drainage system.
F) LUMBAR CATHETER (STANDARD)
Lumbar catheter is one of the components of the lumboperitoneal catheter kit within the lumboperitoneal shunt system. Lumboperitoneal catheter kit consists of lumbar catheter and peritoneal catheter. Lumbar catheter is used to transfer excess CSF from the subarachnoid cavity to the shunt; while the shunt delivers the CSF with a pre-arranged pressure level to the peritoneal cavity.
