Intended Use
Draining and monitoring of CSF flow from the lateral ventricles or lumbar subarachnoid space is indicated in selected patients to: - · Reduce intracranial pressure (ICP), e.g., pre, intra- or postoperative. - · Monitor CSF chemistry, cytology, and physiology. - · Provide temporary CSF drainage in patients with infected cerebrospinal fluid shunts. Monitoring of intracranial pressure (ICP) is indicated in selected patients with: - · Severe head injury - · Subarachnoid hemorrhage graded III, IV, or V preoperatively - · Reye's syndrome or similar encephalopathies - Hydrocephalus - · Intracranial hemorrhage - · Miscellaneous problems when drainage is to be used as a therapeutic maneuver Monitoring can also be used to evaluate the status pre- and postoperatively for space-occupying lesions.
Device Description
The SED System is based upon traditional gravity-based drainage systems, but is designed to allow for the automated regulation of ICP or CSF drainage volume without the need for continuous manual measurements, adjustments and interventions. The SED System consists of an electromechanical, software embedded SED Console and a sterile, disposable SED Cartridge, which includes all components necessary to attach to the external drainage catheter via a luer-lock connector and to a drainage bag that collects the drained fluid. The SED System is mounted on an IV pole, with the SED Console positioned by the user at an easy-to-view height, while the drainage bag is positioned below the lowest possible patient head position or lumbar puncture site, which is considered to be below the height of a hospital bed. The SED System automatically maintains a set drainage rate (for lumbar use) or set ICP (for ventricular use) using a drip counter or pressure sensors (transducers), respectively, and an automated stepper-motor pinching mechanism that compresses or releases the system's compliant drain tubing in order to control the degree of CSF flow (i.e., equivalent to the alteration of CSF flow that happens when a traditional gravity drain is manually raised or lowered). The SED System displays the measured drainage or ICP information, while additionally incorporating multiple alarms provided by its automated functionality. The SED System can thus automatically compensate for patient movement, allow far greater mobility (via a battery backup) and also alert hospital staff if the ICP exceeds the set maximum or minimum levels for a particular patient, as well as if low or high CSF drainage values are ever exceeded for a particular lumbar patient.
More Information

Not Found

No
The device description focuses on electromechanical components, software for automated regulation based on sensors (drip counter, pressure sensors), and basic control mechanisms (stepper-motor pinching). There is no mention of AI, ML, or any learning or adaptive algorithms. The software testing described is standard verification and validation, not related to AI/ML model training or evaluation.

Yes

The device is used to reduce intracranial pressure (ICP) and provide temporary CSF drainage, both of which are therapeutic maneuvers.

Yes

The device is explicitly indicated to "Monitor CSF chemistry, cytology, and physiology" and "Monitoring of intracranial pressure (ICP) is indicated in selected patients", which are diagnostic functions.

No

The device description explicitly states the system consists of an "electromechanical, software embedded SED Console" and a "sterile, disposable SED Cartridge," indicating the presence of significant hardware components beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes the device's function as draining and monitoring CSF flow and intracranial pressure. It mentions monitoring CSF chemistry, cytology, and physiology, but the primary function is the physical management and monitoring of CSF, not the in vitro analysis of biological samples to provide diagnostic information.
  • Device Description: The description details an electromechanical system with a disposable cartridge that physically controls and measures CSF flow and pressure. It does not describe components or processes for analyzing biological samples outside the body for diagnostic purposes.
  • Lack of IVD Characteristics: The description and testing summary do not mention any aspects typical of IVD devices, such as reagents, assays, sample preparation for analysis, or performance metrics related to diagnostic accuracy (like sensitivity, specificity, etc.).

The device is a therapeutic and monitoring system for managing CSF and ICP in vivo, not a device for performing diagnostic tests on biological samples in vitro.
