No
The device description focuses on mechanical components (burette, stopcock, valve, float) for volume limiting and drainage, with no mention of software, algorithms, or data processing that would indicate AI/ML. The performance studies also focus on physical properties and function.
Yes
The device is used to reduce intracranial pressure and provide temporary drainage of CSF, which are therapeutic interventions.
Yes
The device is used to monitor CSF and ICP, which are diagnostic activities.
No
The device description clearly outlines physical components such as catheters, luer connections, patient lines, drainage bags, burettes, stopcocks, and a volume limiting mechanism with a valve and float. These are all hardware components, indicating the device is not software-only.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to drain and monitor cerebrospinal fluid (CSF) from the patient's body (lateral ventricles and lumbar subarachnoid space) to reduce intracranial pressure, monitor CSF, and provide temporary drainage. This is a direct interaction with the patient's physiological system.
- Device Description: The device is a system for external drainage and monitoring of CSF. It involves catheters, lines, a burette, and a drainage bag. This describes a system for managing fluid within the body and collecting it externally.
- Lack of In Vitro Activity: An IVD is designed to examine specimens outside of the body (in vitro) to provide information about a patient's health. This device does not perform any analysis or testing on the collected CSF to diagnose or monitor a condition based on the properties of the fluid itself. It simply collects and measures the volume.
The device is a medical device used for managing and monitoring a physiological process within the patient's body, not for analyzing a specimen in a laboratory setting.

Intended Use / Indications for Use
The LimiTorr™ Volume Limiting External CSF Drainage and Monitoring Systems allow for drainage and monitoring of CSF from the lateral ventricles of the brain and the lumbar subarachnoid space in selected patients to reduce intracranial pressure (ICP), to monitor CSF, to provide temporary drainage of CSF in patients with infected CSF shunts, and the monitoring of ICP.

Device Description
The LimiTorr™ Volume Limiting External CSF Drainage and Monitoring Systems are designed to externally drain cerebrospinal fluid (CSF) from the lateral ventricles of the brain or the lumbar subarachnoid space to a drainage bag in selected patients. The systems connect to a ventricular or lumbar catheter via a luer connection to a patient line and ultimately to a drainage bag. In most of the systems, the patient line is connected to a graduated burette that is then connected to the drainage bag. CSF can be collected and measured in the burette and subsequently emptied into the drainage bag by opening the stopcock placed in line between the burette and the drainage bag.
These systems are designed for single use only.
The Limitorr™ Volume Limiting External CSF Drainage and Monitoring Systems include a mechanism designed to limit the volume of CSF colleted to a nominal volume. The volume limiting mechanism consists of a valve mounted to the top of the float that rises as the fluid collects in the burette and seals when the nominal volume is reached.

§ 882.5550 Central nervous system fluid shunt and components.
(a)
Identification. A central nervous system fluid shunt is a device or combination of devices used to divert fluid from the brain or other part of the central nervous system to an internal delivery site or an external receptacle for the purpose of relieving elevated intracranial pressure or fluid volume (e.g., due to hydrocephalus). Components of a central nervous system shunt include catheters, valved catheters, valves, connectors, and other accessory components intended to facilitate use of the shunt or evaluation of a patient with a shunt.(b)
Classification. Class II (performance standards).

Substantial Equivalence:
The LimiTorr™ Volume Limiting External CSF Drainage and Monitoring Systems are substantially equivalent in function and intended use to the unmodified MoniTorr™ External CSF Drainage and Monitoring Systems which have been cleared to market under Premarket Notification 510(k) K022554.
Intended use:
The LimiTorr™ Volume Limiting External CSF Drainage and Monitoring Systems allow for drainage and monitoring of CSF from the lateral ventricles of the brain and the lumbar subarachnoid space in selected patients to reduce intracranial pressure (ICP), to monitor CSF, to provide temporary drainage of CSF in patients with infected CSF shunts, and the monitoring of ICP.

Conclusion
The LimiTorr™ Volume Limiting External CSF Drainage System is substantially equivalent to the unmodified MoniTorr ICP™ system. These modifications do not affect the intended use, the fundamental scientific technology of the device and doe not raise new issues of safety and effectiveness
