No.
The device is a planning and intraoperative guidance system that assists surgeons in positioning instruments; it does not directly treat a disease or condition.
No
The Stryker Navigation System is described as a "planning and intraoperative guidance system" that assists in the "positioning of instruments for cranial procedures." Its primary function is to guide surgeons during surgery, not to diagnose medical conditions.
No
The submission describes a system that includes hardware components such as a platform (computer, camera, IO-Tablet), navigated instruments (patient tracker, pointer, etc.), accessories (battery), and a CranialMask Tracker which contains a flexible printed circuit board (PCB) mask, housing unit, tracking diodes, LED, communication receiver, battery, and switch. While software is a key component, the device is not solely software.
Based on the provided information, the Stryker Navigation System, with the CranialMap software application, is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Stryker Navigation System's Intended Use: The intended use clearly states that the system is a "planning and intraoperative guidance system to enable open or percutaneous computer-assisted surgery." It assists in the positioning of instruments during surgical procedures.
- Device Description: The description reinforces that the system provides "intraoperative guidance to the surgeon by displaying the position of navigated surgical instruments relative to the medical images." It does not analyze biological specimens.
The system utilizes medical images (CT, MRI, etc.) and provides guidance based on these images and the position of surgical instruments. This is a surgical navigation and planning system, not a device that performs tests on samples taken from the body.
