Intended Use
The HAKIM Micro Programmable (HMP) Valve System is an implantable device that provides constant intraventricular pressure and drainage of cerebrospinal fluid (CSF) for the management of hydrocephalus.
Device Description
The HMP Valve System is a hydrocephalus shunt designed to allow the surgeon to change the valve opening pressure without surgical intervention. Intraventricular pressure is maintained at a constant level by the device's ruby ball-in-cone valve seat design. The center of a flat spring is attached to a fixed fulcrum, with one end resting on the ruby ball and the other end resting on an eighteen position spiral staircase shaped cam that rotates on a titanium pivot. When the cam rotates the tension on the spring changes as the distal end of the spring moves up or down the cam. The opening pressure of the valve is thereby adjusted. During programming, the programmer transmits a coded magnetic signal to the device, causing the cam to rotate. The device has 18 pressure settings, ranging from 30mm to 200mm H20, in 10mm increments.
More Information

Not Found

No
The device description details a purely mechanical and magnetic mechanism for adjusting valve pressure. There is no mention of algorithms, learning, or data processing that would indicate AI/ML.

Yes
The device is used for the management of hydrocephalus, which is a medical condition, by providing constant intraventricular pressure and drainage of cerebrospinal fluid.

No

The device is an implantable hydrocephalus shunt that drains cerebrospinal fluid to manage hydrocephalus, which is a treatment, not a diagnostic, function.

No

The device description clearly details a physical, implantable valve system with mechanical components (ruby ball, spring, cam, pivot) and a magnetic programming mechanism. This is not a software-only device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the HAKIM Micro Programmable (HMP) Valve System is an implantable device for the management of hydrocephalus by draining cerebrospinal fluid. This is a therapeutic and mechanical function performed within the body.
  • Device Description: The description details a mechanical valve system with a spring, ball, and cam that physically regulates fluid pressure. This is a physical mechanism, not a test performed on a sample outside the body.
  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health status. This device does not perform such tests.

The HAKIM Micro Programmable Valve System is a Class III implantable medical 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)

Predicate Device Comparison 5.

The HMP Valve System is substantially equivalent in terms of intended use, materials, design, manufacturing, and function to the CODMAN HAKIM Micro Precision Valve System (K973774). Both devices utilize the same ball-in-cone Frecision valve oyotom (traventricular pressure. Depending on the 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.

While the pressure regulating mechanism is identical in both devices, the variable pressure setting feature is only available with the HMP Valve System, while the HAKIM Micro Precision Valve System is available in five fixed pressure ranges.

Device Testing Summary 6.

Performance testing was conducted to confirm device functionality for its intended use as a hydrocephalus shunt. Results of all testing demonstrate that the HAKIM Micro Programmable Valve System is equivalent to currently marketed products in its performance as a hydrocephalus shunt.
