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.

Device Story

System provides external drainage and monitoring of cerebrospinal fluid (CSF) from lateral ventricles or lumbar subarachnoid space. Device connects to ventricular or lumbar catheter via luer connection; fluid flows into graduated burette for measurement; stopcock allows emptying into drainage bag. Integral volume-limiting mechanism uses float-mounted valve that rises with fluid level to seal burette at nominal volume. Used in clinical settings for patients requiring ICP reduction or temporary drainage for infected shunts. Healthcare providers monitor CSF levels and ICP via system. Single-use device.

Clinical Evidence

Bench testing only. Testing included strength of bonded components, leakage, drainage, sealing mechanism performance, and package integrity.

Technological Characteristics

External CSF drainage system; includes graduated burette and drainage bag. Features mechanical volume-limiting float-valve. Single-use. Luer connections. Needleless sampling sites included to reduce needlestick risk.

Indications for Use

Indicated for patients requiring external CSF drainage and monitoring from lateral ventricles or lumbar subarachnoid space to reduce intracranial pressure, monitor CSF, or provide temporary drainage for infected CSF shunts.

Regulatory Classification

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.

| Common Name: | External Cerebrospinal Fluid Drainage and Monitoring System |
| Classification Name: | Central Nervous System Shunt and Components JXG |

#### 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.

#### 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

{1}------------------------------------------------

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.

# Safety

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

The systems have been tested for strength of bonded components, leakage, drainage, sealing mechanism performance and package integrity. Additionally, the needleless sampling sites were designed to reduce needlestick injuries and subsequent exposure to infected fluids.

# 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

Dear Ms. Welsh:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set
