No
The device description and performance studies focus on mechanical and magnetic principles for valve operation and adjustment, with no mention of AI or ML.
Yes
The device is described as an "implantable device that provides constant intraventricular pressure and drainage of CSF for the management of hydrocephalus," indicating its direct role in treating a medical condition.
No
Explanation: The device is an implantable valve used to manage hydrocephalus by regulating CSF pressure. While it allows for non-invasive reading or adjustment of its setting, its primary function is therapeutic management rather than diagnostic assessment of a condition.
No
The device described is an implantable valve and a tool kit that uses magnetic force for adjustment. These are clearly hardware components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the management of hydrocephalus by providing constant intraventricular pressure and drainage of CSF. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
- Device Description: The device is an implantable valve designed to regulate the flow of CSF within the body. It is a mechanical device that directly interacts with the patient's physiology.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, urine, tissue, etc.) outside of the body to provide information for diagnosis, monitoring, or screening.
The device is an implantable medical device used for treatment, not an in vitro diagnostic device used for testing samples.

Device Description
The Codman Certas Plus Programmable Valve is a sterile, single use, implantable device designed for shunting cerebrospinal fluid (CSF) for the treatment of hydrocephalus.
The Codman Certas Plus Programmable Valves are pressure-regulating valves utilizing the ruby ball-in-cone principle with a pressure inducing spring design. Intraventricular pressure is maintained by the ball and cone valve seat design. As the differential pressure across the shunt increases, the ball further displaces from the cone, through which CSF flows, thereby increasing flow and re-establishing the selected pressure. The ball is manufactured of synthetic ruby, as is the matching cone. Together these components provide a precise fit for regulating the flow of CSF through the valve.
The valve is available with 8 different performance settings for constant intraventricular pressure and drainage of CSF. Seven (7) of the settings provide for a change in operating pressure, with a range of 25 to 215 mmH2O. The eighth setting provides a minimum opening pressure of '400' mmH20, thus allowing a physician to turn the valve “virtually off” without the need to surgically remove the valve to limit flow. The pressure of the valve is set preoperatively and can be noninvasively changed post-implantation by using the Codman Certas Tool Kit, which employs magnetic force to select one of the 8 settings.
