No
The description focuses on passive optical tracking and mapping instruments onto pre-operative images, with no mention of AI or ML algorithms for image analysis, prediction, or other functions.
No
The device aids physicians during surgery by mapping surgical positions onto medical images for guidance, but it does not directly treat or prevent disease.
No
The device is described as an "image-guided surgery medical device" that aids physicians during surgery by mapping instrument positions onto pre-operative MRI or CT images to help with "localization of tumors and other surrounding anatomic structures." This is a surgical navigation and guidance tool, not a device that makes a diagnosis.
No
The device description explicitly lists multiple hardware components beyond just software, including an optical position sensor, tracked devices, and an LCD display monitor.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Function: The Explorer™ Liver --- Passive Tracking device is used during open liver surgical procedures. It helps guide the physician by mapping the position of surgical instruments onto pre-operative images. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "open liver surgical procedures where image-guidance may be appropriate." This is a surgical guidance tool, not a diagnostic test performed on a sample.
Therefore, the device falls under the category of a surgical navigation or image-guided surgery system, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Explorer Liver --- Passive Tracking device is indicated for open liver surgical procedures where image-guidance may be appropriate and where the patient can tolerate long apneic periods under general anesthesia.

Device Description
The Explorer Liver --- Passive Tracking is an image-guided surgery medical device specifically designed to aid physicians during open liver procedures. The device is capable of mapping the current surgical position of tracked instruments onto preoperative, patient-specific MRI or CT medical images. These images can then be used as a guide by the physician for more accurate localization of tumors and other surrounding anatomic structures during liver surgery. The Explorer Liver --- Passive Tracking system consists of eight (8) components which are listed below:
- An image-guided surgery software platform installed on a personal computer (PC) (1)
- (2) An optical position sensor --- the Polaris Spectra or Vicra that can accurately localize the tracked devices listed below in passive tracking mode
- . A passive tracked abdominal reference (used for definition of coordinate and instrument calibration)
- . A passive tracked Localization Pen Probe
- . A passive tracked Laser Range Scanner (LRS)
- Two passive tracked adapters (can be attached onto up to two rigid surgical instruments ● simultaneously and used for their localization in 3-D surgical space)
- (3) An LCD display monitor.

Device Modifications through this special 510(K) submission IX.
The modification on the subject device (Explorer --- Passive Tracking) over the previous cleared device (K071063 & K093494) through this special 510(K) submission is changing the tracking mode from active to passive. This device modification resulted in subsequent changes to the hardware, including the position sensor and the design of the tracked instruments. By replacing the active Localizer component in the software system with a passive Localizer component, the subject device is allowed to recognize each passive tracked instrument with its unique rigid body design.
