No
The description focuses on the mechanical function of the valve as a variable resistance device and does not mention any computational or learning capabilities.
Yes
The device is indicated for the treatment of communicating hydrocephalus by shunting CSF, which directly addresses a medical condition.
No
The device is described as an implantable system used to shunt CSF, which is a therapeutic function, not a diagnostic one.
No
The device description explicitly states it is an "implantable device" and lists physical accessories required for its use, indicating it is a hardware-based medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Description: The provided text describes an implantable system used to drain cerebrospinal fluid (CSF) from the lumbar region to the peritoneal cavity. This is a surgical procedure performed within the body, not an examination of a specimen outside the body.
- Intended Use: The intended use is to treat communicating hydrocephalus by shunting CSF. This is a therapeutic intervention, not a diagnostic test performed on a specimen.
The device is a medical device, specifically an implantable surgical device, but it does not fit the definition of an In Vitro Diagnostic.

Device Description
The OSV II® Lumbar Valve System (OSV II Valve) and the OSV II® Low Flow Lumbar Valve System (OSV II Low Flow Valve) are implantable devices for controlled cerebrospinal fluid drainage (CSF) from the lumbar subarachnoid region to the peritoneal cavity. Unlike conventional valves, they are variable resistance valves which maintain a drainage rate constant within the physiological range (for the specified populations and disorders) of intracranial pressure. They maintain a drainage rate around 20ml/hr for OSV II Valves and around 10ml/hr for OSV II Low Flow Valves.
The OSV II Lumbar Valve System and OSV II Low Flow Lumbar Valve System are provided with accessories including a 14G tuohy needle, a F5 lumbar catheter, a guidewire, a luer lock connector and a F8-F5 stepdown connector, which are required for using the valves in a lumbar approach. The designs of the accessories are identical to the accessories currently provided with the Integra H-V Lumbar Valve System.

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)

Indications for Use:
Both the OSV II Lumbar Valve System and the OSV II Low Flow Lumbar Valve System are indicated as implantable systems used in the treatment of patients with communicating hydrocephalus to shunt CSF from the lumbar subarachnoid region to the peritoneal cavity.
Principle of Operation:
The Principle of Operation of both the OSV II Lumbar Valve System and OSV II Low Flow Lumbar Valve System are as follows:
The variable flow restrictor consists of a silicone elastomer diaphragm, synthetic ruby seat, and notched pin. The diaphragm reacts to differential pressure (DP) variations. The seat is inserted into the center of the diaphragm. As differential pressure varies, the clearance between the seat and the pin increases depending on seat movement along the pin. Changes in the seat and pin clearance vary flow rates.
Note - Differential pressure/flow characteristics for each valve are verified to be within specification at time of manufacture.
The three stages of operation of the OSV II® Lumbar Valve System and the OSV II Low Flow Lumbar Valve System are defined below:
Stage I - Low Differential Pressure
This stage begins when the flow rate through the valve reaches 5ml/hr (DP will be between 30 and 80 mm H20). The valve remains in Stage I with CSF flow rates up to 18 ml/hr (up to 8 ml/hr for the OSV II Low Flow) (DP will be between 40 and 120 mm and 120 mm H20).
Stage II - Flow Regulation
When the DP increases, the valve operates as a variable resistance flow regulator. At DP ranges between 120 and 300 mm H20, the valve restricts flow between 18 and 30 ml/hr (between 8 and 17 ml/hr for the OSV II Low Flow).
Stage III - Pressure Relief Mode
Should the intraventricular pressure (IVP) elevate abruptly, the shunt operates in a rapid flow rate mode to facilitate IVP normalization. The valve then reverts to Stage II or I, depending upon conditions.
Materials:
The materials of composition for both the OSV II Lumbar Valve System and OSV II Low Flow Lumbar Valve System are identical: silicone elastomer with or without barium sulfate, polysulfone, synthetic ruby, silicone adhesive, tantalum, polypropylene and epoxy.
The accessories include a lumbar catheter and suture clamp made of silicone elastomer with

barium sulfate. The guidewire used to introduce the catheter is made of stainless steel, coated with polytetrafluoroethylene (PTFE), the stepdown connector is made of polypropylene with barium sulfate and the luer connector (to flush catheter) is made of polycarbonate. The 14G tuohy needle is made of stainless steel, with polycarbonate wings. The materials used in the accessories are identical to those materials used in the H-V Lumbar Valve accessories. except the F8-F5 stepdown connector is made of stainless steel in the H-V Lumbar Valve and is made of polypropylene with barium sulfate for the proposed OSV II and OSV II Low Flow valves. The current OSV II and Integra NPH Low Flow Valve systems already provide straight connectors made of the same polypropylene with barium sulfate and a lumbar catheter made with silicone elastomer.
Substantial Equivalence:
The proposed OSV II and OSV II Low Flow Valves are substantially equivalent in function to the currently approved OSV II and Integra NPH Low Flow Valve Systems cleared to market by FDA under K971799, K081773, and K042192. This bundled 510(k) supports the use of both valve systems using a lumbo-peritoneal approach. The accessories provided allow for a lumbar approach and are substantially equivalent to the accessories provided with the Integra H-V Lumbar Valve System, which was cleared by FDA under K944595 for the same intended use. These accessories include a 14G tuohy needle, F5 lumbar catheter, guidewire, stepdown connector, and suture clamp.
The OSV II Lumbar Valve System and OSV II Low Flow Lumbar Valve System are designed the same as the valves currently used with the OSV II and Integra NPH Low Flow Valve Systems provided for the ventricular approach. Since the valves are the same, the product and performance specifications are the same as the predicate valves.
The Principle of Operation, intended use, design, materials of composition and manufacturing processes for both the OSV II Lumbar Valve System and OSV II Low Flow Lumbar Valve System are the same as for the current OSV II and Integra NPH Low Flow hydrocephalus valves. The labeling has been revised to include the indications for treatment of patients with communicating hydrocephalus to shunt CSF from the lumbar subarachnoid region to the peritoneal cavity. Based upon the stated information and supported by the clinical evidence included in this 510(k), Integra concludes that both systems are equivalent to the predicates defined in this submission.
