No
The summary describes surgical navigation instruments and their use with existing navigation systems. There is no mention of AI or ML in the device description, intended use, or performance studies. The focus is on mechanical instruments and their compatibility with image-guided navigation.

No
The device is a set of instruments (Nav Awl, Nav Drill Guide, Nav Tap, Nav Screwdriver, Nav Handle) used to assist surgeons in precise positioning of surgical instruments or spinal implants during spine surgery, particularly for pedicle screw placement. These are tools for guidance and preparation, not devices that directly provide therapy.

No

The device is a surgical navigation instrument designed to assist in the precise positioning of surgical instruments or spinal implants during spine surgery. It is an intraoperative guidance system, not a diagnostic device that identifies or characterizes a disease or condition.

No

The device description explicitly lists physical instruments (Nav Awl, Nav Drill Guide, Nav Tap, Nav Screwdriver, Nav Handle) as components of the device. While it is used with navigation systems (which likely involve software), the device itself includes hardware.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Remex Spine Surgery Navigation Instrument is a set of surgical tools (Awl, Drill Guide, Tap, Screwdriver, Handle) designed to be used during surgery to assist with the precise positioning of instruments and implants based on medical imaging.
  • Intended Use: The intended use clearly states it's for "precise positioning of surgical instruments or spinal implants during general spine surgery" and acts as a "planning and intraoperative guidance system." This is an in vivo application (within the living body), not in vitro (outside the living body).
  • No Sample Analysis: The description does not mention any analysis of biological samples.

Therefore, the Remex Spine Surgery Navigation Instrument is a surgical navigation system component used in vivo during spine surgery, not an in vitro diagnostic device.
