Intended Use
The Zeta Cranial Navigation System is a stereotaxic image guidance system intended for the spatial positioning and orientation of neurosurgical instruments used by surgeons. The device is indicated only for cranial surgery where reference to a rigid anatomical structure can be identified, does not require rigid fixation of the patient, and does not require fixation of a navigated instrument guide to the patient. The system is intended to be used in operating rooms and in less acute surgical settings such as interventional procedure suites.
Device Description
The Zeta Cranial Navigation System is a stereotaxic, image guided planning and intraoperative guidance system enabling computer-assisted cranial interventional procedures. The system assists surgeons with the precise positioning of surgical instruments relative to patient anatomy by displaying the position of navigated surgical instruments relative to 3D preoperative medical scans.
More Information

Not Found

No
The summary describes a standard image-guided navigation system that uses pre-operative scans and instrument tracking for spatial positioning. There is no mention of AI, ML, or related concepts like image processing that might suggest AI/ML involvement. The performance studies focus on accuracy and human factors, not AI/ML specific metrics.

No.
The device is an image guidance system that assists surgeons with precise positioning of instruments; it does not directly treat or diagnose a disease or condition.

No.
The device is a surgical navigation system, an intraoperative guidance system that assists with the precise positioning of surgical instruments relative to patient anatomy during cranial surgery, rather than diagnosing a condition.

No

The device description explicitly states it is a "system" that assists surgeons with the precise positioning of surgical instruments relative to patient anatomy by displaying the position of navigated surgical instruments relative to 3D preoperative medical scans. This implies the system includes hardware components for tracking and displaying instrument position, not just software for planning and image processing. The bench testing also mentions "Dynamic patient motion" and "Other worst-case physical and environmental conditions," which are typically associated with hardware performance testing.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. They are used outside the body (in vitro).
  • Zeta Cranial Navigation System Function: The description clearly states that the Zeta Cranial Navigation System is a stereotaxic image guidance system used for the spatial positioning and orientation of neurosurgical instruments during cranial surgery. It assists surgeons in navigating within the patient's body based on pre-operative images.

The system's purpose is to guide surgical procedures on the patient, not to analyze samples from the patient. Therefore, it falls under the category of a surgical navigation or guidance system, not an IVD.

Dear Dr. Stolyarov:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.
