Features ruby ball-in-cone valve seat; flat spring attached to fixed fulcrum; eighteen-position spiral staircase cam on titanium pivot. Surgeon adjusts opening pressure non-invasively via external programmer transmitting coded magnetic signal to rotate cam. Pressure settings range 30-200mm H2O in 10mm increments. Used in clinical settings by neurosurgeons. Benefits patient by allowing pressure adjustment without repeat surgery. ## Clinical Evidence Bench testing only. Performance testing conducted to confirm device functionality for intended use as a hydrocephalus shunt; results demonstrate equivalence to currently marketed products. ## Technological Characteristics Implantable shunt; ruby ball-in-cone valve seat; stainless steel flat spring; titanium pivot; 18-position spiral staircase cam. Pressure range: 30-200mm H2O. Magnetic programming interface. Class II device. ## Regulatory 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. ## Predicate Devices - CODMAN HAKIM Micro Precision Valve System ([K973774](/device/K973774.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Johnson & Johnson Professional, Inc. 325 Paramount Drive Ravnham, MA 02767 。 Diane Minear, Senior Regulatory Consultant, (508) 828-3532 #### 2. Device Name | Proprietary Name: | HAKIM Micro Programmable Valve System | |----------------------|------------------------------------------------------| | Common Name: | Hydrocephalus Shunt | | Classification Name: | Central Nervous System Fluid Shunt and
Components | | Regulatory Class: | Class II by 21 CFR §882.5550 | #### 3. 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. #### 4. 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. {1}------------------------------------------------ #### 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. {2}------------------------------------------------ Public Health Service Image /page/2/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.
