The description focuses on mechanical components and manual operation for precise depth control, with no mention of AI, ML, or image processing.
No.
The device description indicates it is used for "precise depth control of probes during stereotactic neurosurgical procedures," which suggests it is an accessory used to facilitate a procedure, not a device that directly treats a condition.
No
The device is described as assisting in the physical placement and depth control of probes during neurosurgical procedures, which is a procedural/therapeutic function, not a diagnostic one.
No
The device description explicitly lists multiple hardware components (guide block base, stanchion probe holder, drive stanchion, drive box, digital display, and cable) and describes a manually operated mechanical function (advancing a probe).
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "precise depth control of probes during stereotactic neurosurgical procedures." This describes a surgical tool used in vivo (within a living organism) to guide a probe.
- Device Description: The description details a mechanical device that is mounted to a stereotaxic frame and manually operated to advance a probe. This is consistent with a surgical instrument.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) in vitro (outside of the body) to provide information about a physiological state, health, or disease.
IVD devices are specifically designed for testing samples taken from the body to diagnose, monitor, or screen for conditions. This device's function is entirely focused on guiding a probe during a surgical procedure on a patient.

Kevin J. O'Connell Regulatory Engineer Radionics Software Applications, Inc. 22 Terry Avenue Burlington, MA 01803 Tel .: (781) 272-1233 Fax: (781) 272-2428
This summary was prepared on August 12, 1999.
- 2.0 The name of the device is the Cosman Robert Wells Functional Probe Microdrive (CRW-FMD). The common name is microdrive for stereotaxic frame, and it is classified as a stereotaxic instrument.
- 3.0 The CRW-FMD is substantially equivalent to the Microdrive for Probes, an accessory for the Todd Wells Stereotaxic Guide that was commercially available prior to May 28, 1976.
- 4.0 The CRW-FMD is designed for the precise depth control of probes during stereotactic neurosurgical procedures. The CRW-FMD is mounted to a stereotaxic frame, and manually operated to advance a probe along the z-axis of a stereotactic trajectory. The main components of the system are: guide block base, stanchion probe holder, drive stanchion, drive box, digital display, and cable
- 5.0 The CRW-FMD like its predicate is intended for the precise depth control of probes during stereotactic neurosurgical procedures.
- 6.0 The technological characteristics are the same or similar to those found with the predicate device.

Dear Mr. O'Connell:
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 requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) 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 devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
