Intended Use
The NeuroSensor® Cerebral Blood Flow and Intracranial Pressure Monitoring System is intended for use by a qualified clinician in monitoring cerebral blood flow in patients at risk of cerebral ischemia, and for the direct monitoring of intracranial pressure in intraparenchymal applications.
Device Description
Each NeuroSensor® system consists of a single-use probe and introducer for the continuous real-time measurement of Cerebral Blood Flow (CBF) and Intracranial Pressure (ICP), and a monitor for the display and storage of these measured parameters and the computation and display of derived parameters. The NeuroSensor® monitor can be connected to a hospital bedside monitor for display of ICP. The NeuroSensor® monitor can accept Systemic Arterial Pressure (SAP) data from a hospital bedside monitor, and can use this data and the measured CBF and ICP to compute Cerebral Perfusion Pressure (CPP) and Cerebrovascular Resistance (CVR).
More Information

Not Found

No
The document describes a system for measuring and displaying physiological parameters (CBF, ICP, SAP) and computing derived parameters (CPP, CVR). There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML applications in medical devices. The description focuses on real-time measurement and computation based on standard physiological formulas.

No
The device is a monitoring system intended for diagnostic purposes (monitoring cerebral blood flow and intracranial pressure), not for directly treating a condition.

Yes

Explanation: The device is used to monitor cerebral blood flow and intracranial pressure, which are physiological parameters used to assess the patient's condition and diagnose potential issues like cerebral ischemia.

No

The device description explicitly states that the system consists of a single-use probe, introducer, and a monitor, indicating the presence of hardware components beyond just software.

Based on the provided information, the NeuroSensor® Cerebral Blood Flow and Intracranial Pressure Monitoring System is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • NeuroSensor® Function: The NeuroSensor® system directly monitors physiological parameters (cerebral blood flow and intracranial pressure) within the patient's body (intraparenchymal). It does not analyze samples taken from the body.

Therefore, the NeuroSensor® is an in vivo monitoring device, not an in vitro diagnostic device.
