Intended Use
The CODMAN HAKIM™ Micro Precision Valve System is an implantable device that provides constant intraventricular pressure and drainage of CSF for the management of hydrocephalus and other conditions in which CSF flow and absorption are impaired.
Device Description
The CODMAN HAKIM™ Micro Precision Valve incorporates a flat 316L stainless steel spring. Intraventricular pressure is maintained at a constant level by the synthetic ruby ball-in-cone valve seat design. Depending on the cerebrospinal (CSF) flow rate and /or viscosity, the ball moves up or down within the cone under the control of the calibrated flat stainless steel spring. The cross section of the valve through which CSF flows automatically increases or decreases, therefore maintaining the selected pressure. The silicone rubber housing of the CODMAN HAKIM™ Micro Precision Valve has a flat bottom to better stabilize the position of the valve underneath the scalp. The flat underside of the valve should be placed against the bone. The operating pressures of the valve are set and verified at the time of manufacture. The valve is classified by the operating pressure, not by the opening and closing pressures. The total pressure of the valve is controlled by the inlet valve. The CODMAN HAKIM™ Micro Precision Valve is available in five pressure settings: Very Low 10 ± 10 mm H2O, Low 40 ± 10 mm H2O, Medium 70 ± 10 mm H2O, Medium High 100 ± 10 mm H2O, High 130 ± 10 mm H2O. The materials of the CODMAN HAKIM™ Micro Precision Valve are the same materials that are used in the currently marketed Codman-Medos Shunt Valve System (K944222). The only difference in materials is in the accessories. The stainless steel connector described in K944555 has been replaced with a nylon connector that was cleared in the Accu-Flo Pressure Valve submission (K853215A).
More Information

K944555, K853215A

No
The device description details a purely mechanical valve system that regulates pressure based on physical principles (spring tension, ball-in-cone design) and pre-set manufacturing parameters. There is no mention of software, algorithms, or adaptive learning capabilities.

Yes.
The device drains CSF for the management of hydrocephalus and other conditions where CSF flow is impaired, which is a therapeutic intervention.

No

The device is described as an implantable valve that regulates intraventricular pressure and drains CSF, which is a therapeutic function, not a diagnostic one.

No

The device description clearly details a physical, implantable device made of stainless steel and silicone rubber with mechanical components (spring, ball-in-cone valve seat). There is no mention of software as the primary or sole component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to manage hydrocephalus and other conditions by providing constant intraventricular pressure and drainage of CSF. This is a therapeutic and physiological function performed within the body.
  • Device Description: The description details an implantable mechanical valve system designed to regulate fluid pressure and flow in vivo. It does not describe a device used to examine specimens derived from the human body in vitro to provide information for diagnosis, monitoring, or compatibility testing.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, calibrators, controls, or any other elements typically associated with IVD devices.

Therefore, the CODMAN HAKIM™ Micro Precision Valve System is a therapeutic implantable device, not an In Vitro Diagnostic device.

§ 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).

Dear Ms. Johnson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements , as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition. FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for
