No
The description focuses on a mechanical valve with magnetic adjustment and catheters, with no mention of AI or ML capabilities.
Yes
The device is intended for the management of communicating hydrocephalus and idiopathic intracranial hypertension, which are medical conditions, and it provides continued CSF flow, indicating a therapeutic function.
No
The device is a shunt system designed to manage cerebrospinal fluid flow, not to diagnose a condition. Its function is therapeutic, to treat communicating hydrocephalus and idiopathic intracranial hypertension, rather than to identify or characterize a disease state.
No
The device description clearly states that the system is comprised of physical components including catheters, valves, and accessories, and is adjusted using magnetic tools. This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes a device that is implanted to manage cerebrospinal fluid flow within the body. This is a therapeutic intervention, not a diagnostic test performed on samples outside the body.
- Device Description: The description details physical components like catheters, valves, and adjustment tools, all designed for surgical implantation and mechanical function within the patient.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, CSF in vitro), reagents, or any process related to diagnosing a condition by examining samples outside the body.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition. This device clearly falls outside that definition.

Intended Use / Indications for Use
The Strata NSC Lumboperitoneal Shunt System provides continued cerebrospinal fluid (CSF) flow from the subarachnoid space into the peritoneal cavity. The Strata NSC Lumboperitoneal Valve allows the physician to non-invasively adjust the pressure/flow performance level pre- and post-implantation in order to address changing patient needs. The Strata NSC Lumboperitoneal Shunt System is designed for management of communicating hydrocephalus and may be used in the treatment of idiopathic intracranial hypertension (pseudotumor cerebri) when shunting is an option.

Device Description
The Strata NSC Lumboperitoneal Valve and Shunt Systems are comprised of lumbar and peritoneal catheters, valves and accessories. The lumboperitoneal valve allows the physician to noninvasively adjust the pressure/flow performance level pre- and post-implantation using magnetic adjustment tools in order to address changing patient needs. The lumbar catheters are available in closed-tip and open-tip configurations and have length markers located at 5 cm intervals. A strain relief provides support to and lessens the potential of catheter kinking at the junction of the lumbar catheter to the valve and fixation tabs are provided to anchor catheters at the incisions.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance data demonstrating that the Strata NSC LP valves can be read and adjusted and that they do not migrate when properly implanted in an ovine model is included in this submission to support the indications expansion. Additionally a retrospective clinical review of data which includes prospective follow ups is provided to demonstrate that physicians are able to palpate the valve, determine the direction of flow and to accurately read the pressure level setting using the StrataVarius device consistently with radiographic imaging verification when these shunt systems are used for lumboperitoneal applications.

§ 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)

Device Description:
The Strata NSC Lumboperitoneal Valve and Shunt Systems are comprised of lumbar and peritoneal catheters, valves and accessories. The lumboperitoneal valve allows the physician to noninvasively adjust the pressure/flow performance level pre- and post-implantation using magnetic adjustment tools in order to address changing patient needs.

A strain relief provides support to and lessens the potential of catheter kinking at the junction of the lumbar catheter to the valve and fixation tabs are provided to anchor catheters at the incisions.
Technological Characteristics: The Strata NSC Lumboperitoneal Valve and Shunt Systems incorporate the same technological characteristics as that of the predicate devices and are identical to the currently marketed versions. Each of these devices is intended for draining of cerebral spinal fluid (CSF) from the lumbar subarachnoid space.
Indications for Use:
The Strata NSC Lumboperitoneal Shunt System provides continued cerebrospinal fluid (CSF) flow from the subarachnoid space into the peritoneal cavity. The Strata NSC Lumboperitoneal Valve allows the physician to non-invasively adjust the pressureflow performance level pre- and post-implantation in order to address changing patient needs. The Strata NSC Lumboperitoneal Shunt System is designed for management of communicating hydrocephalus and may be used in the treatment of idiopathic intracranial hypertension (pseudotumor cerebri) when shunting is an option.
The Indications for Use statements cleared in the predicate submission K091312 did not contain language specific to the use of the subject devices for treatment of idiopathic intracranial hypertension (pseudotumor cerebri). The intent of this premarket submission is to expand the indications to include reference to this specific use when warranted.
