Intended Use

The Hermetic Plus™ External CSF Drainage System is indicated for draining and monitoring of cerebrospinal fluid (CSF) from the lateral ventricles of the brain or lumbar subarachnoid space in selected patients to reduce intracranial pressure (ICP), monitor intracranial pressure, to monitor cerebrospinal fluid, and provide temporary CSF drainage for patients with infected hydrocephalic shunts.

Device Story

External CSF drainage system; connects to ventricular or lumbar catheter via luer connection; directs CSF flow to graduated burette and drainage bag. Features antimicrobial vent in burette cap to facilitate drainage and prevent occlusion; needleless sampling sites to reduce needlestick risk. Safety locking knob includes titanium screw; suspension cord lock is plastic. Used in clinical settings for patient management; allows healthcare providers to measure CSF volume and monitor ICP. Benefits include controlled pressure reduction and management of infected shunts. Device is MR safe.

Clinical Evidence

Bench testing only. Evaluated strength of bonded components, leakage, drainage performance, package integrity, and antimicrobial vent resistance to occlusion after 30 minutes exposure to high-protein fluids.

Technological Characteristics

External drainage system; materials include titanium (screw) and plastic (cord lock). Features antimicrobial vent for pressure equalization and drainage facilitation. Needleless sampling sites. MR safe. No software or electronic components.

Indications for Use

Indicated for patients requiring temporary CSF drainage or ICP monitoring via lateral ventricles or lumbar subarachnoid space, including those with infected hydrocephalic 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.

| Proprietary Name: | Hermetic Plus™ External CSF Drainage System |
|----------------------|-------------------------------------------------|
| Common Name: | External CSF Drainage System |
| Classification Name: | Central Nervous System Shunt and Components JXG |

#### Substantial Equivalence:

The Hermetic Plus™ External CSF Drainage System is substantially equivalent in function and intended use to the unmodified External CSF Drainage and Management Systems which has been cleared to market under Premarket Notification 510(k) K972994.

#### Intended use:

The Hermetic Plus™ External CSF Drainage System is indicated for draining and monitoring of cerebrospinal fluid (CSF) from the lateral ventricles of the brain or lumbar subarachnoid space in selected patients to reduce intracranial pressure (ICP), monitor intracranial pressure, to monitor cerebrospinal fluid, and provide temporary CSF drainage for patients with infected hydrocephalic shunts.

# Device Description:

The Hermetic Plus™ External Drainage 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. 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. An antimicrobial vent is included in the burette cap. This antimicrobial vent allows air to enter the burette to facilitate drainage from the burette to the drainage bag while protecting the system from microbial contamination. The

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

antimicrobial vent used on the Hermetic Plus™ systems will allow better drainage of the CSF to the drainage bag and will resist occlusion after contact with CSF without the need for clamping the burette vent tube.

The Safety Locking Knob of the Hermetic Plus™ system will now contain a titanium screw component and the cord lock of the suspension cord has been changed to an all plastic component.

# Safety

The Hermetic Plus™ External CSF Drainage Systems have been demonstrated to be MR safe* when used in the Magnetic Resonance (MR) environment.

*MRI safe is defined by the CDRH Magnetic Resonance Working Group (Feb. 7, 1997) draft document A Primer on Medical Device Interactions with MRI Systems as "The device, when used in the MRI environment, has been demonstrated to present no additional risk to the patient or other individuals, but may affect the quality of the diagnostic information."

Testing has shown that the antimicrobial vent is resistant to occlusion after 30 minutes of exposure to fluids with high protein levels. The systems have been tested for strength of bonded components, leakage, drainage, and package integrity. Additionally, the needleless sampling sites were designed to reduce needlestick injuries and subsequent exposure to infected fluids.

# Conclusion

The Hermetic Plus™ External CSF Drainage System is substantially equivalent to the unmodified External CSF Drainage Management Systems. The modifications do not affect the intended use, the fundamental scientific technology of the device, and do not raise new issues of safety and effectiveness.

Dear Ms. Wallace:

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
