Intended Use
Draining and monitoring of CSF flow from the lateral ventricles 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 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 ventricular 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, which is considered to be below the height of a hospital bed. The SED System automatically maintains a set ICP using pressure sensors (transducers) 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 ICP information and also calculates and displays CSF flow volume output, while additionally incorporating multiple alarms given its automated functionality. The SED System can thus automatically compensate for patient movement, allow greater mobility (via a battery backup) and also alert hospital staff if ever the ICP exceeds the set maximum or minimum levels for a particular patient, as well as if low or high CSF drainage values (as also set by the user) are ever exceeded. The modifications included under this Special 510(k) include the following: - Added ICP Waveform Display to User Interface Screen. - Software loading via USB interface. - Optimization of the SED System's initialization sequence.
More Information

No
The description focuses on automated regulation using pressure sensors and a stepper motor based on set parameters, not learning or adaptive algorithms. The modifications are also related to display, software loading, and initialization, not AI/ML functionality.

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

Yes

The device "Monitors CSF chemistry, cytology, and physiology" and "Monitors intracranial pressure (ICP)", which are diagnostic functions. It also "displays the measured ICP information and also calculates and displays CSF flow volume output," providing information used for diagnosis or guidance of treatment.

No

The device description explicitly states the SED 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. The performance testing also includes verification of hardware elements like the SED Cartridge and the SED System's functionality and pressure resistance.

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 monitoring intracranial pressure. These are direct physiological measurements and interventions performed on the patient.
  • Device Description: The device description details a system that physically interacts with the patient's CSF drainage system (via a luer-lock connector) and uses pressure sensors and a mechanical mechanism to control flow.
  • Lack of In Vitro Activity: An IVD is designed to examine specimens from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any analysis on patient specimens outside the body. It is directly interacting with and managing a physiological process within the patient.

The device is a therapeutic and monitoring device used in vivo (within the body), not an in vitro diagnostic device.

Device Description: The SED System is based upon traditional gravity-based drainage systems, but is designed to allow for the automated regulation of ICP 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 ventricular 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, which is considered to be below the height of a hospital bed.

The SED System automatically maintains a set ICP using pressure sensors (transducers) 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 ICP information and also calculates and displays CSF flow volume output, while additionally incorporating multiple alarms given its automated functionality.

The SED System can thus automatically compensate for patient movement, allow greater mobility (via a battery backup) and also alert hospital staff if ever the ICP exceeds the set maximum or minimum levels for a particular patient, as well as if low or high CSF drainage values (as also set by the user) are ever exceeded.

The modifications included under this Special 510(k) include the following:

  • Added ICP Waveform Display to User Interface Screen. .
