The summary describes navigation-ready instruments that interface with existing navigation systems (VELYS, Brainlab, Medtronic StealthStation). The functionality described is based on tracking the instruments relative to acquired images or anatomical models, which is standard navigation technology and does not indicate the use of AI/ML for tasks like image analysis, prediction, or decision support.
Yes
The device is described as assisting in surgical procedures like discectomy and spinal fusion, involving interventions on anatomical structures, visualization, and nerve stimulation, all of which fall under therapeutic applications.
No
Explanation: The device is described as assisting in locating anatomical structures and facilitating surgical procedures like discectomy and spinal fusion. While it uses imaging data for navigation, its primary function is surgical assistance rather than diagnosing a condition. The TELIGEN Access Probe is indicated for "stimulation of peripheral motor nerves... for location and identification during surgery," which is an intraoperative aid, not a pre-operative diagnosis.
No
The device description clearly outlines physical components such as instruments, adaptors, arrays, and rings, which are hardware. While it interacts with navigation systems (which likely involve software), the device itself is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Function: The TELIGEN Navigation Ready Instruments, Discectomy Navigation Ready Instruments, and Universal Navigation Adaptor Set are surgical instruments and accessories used during surgical procedures on the spine. Their purpose is to assist the surgeon in accessing, visualizing, and performing procedures like discectomy and bony resection, often with the aid of navigation systems.
- Lack of Specimen Analysis: The intended use and device description clearly indicate that these devices are used directly on the patient's anatomy during surgery. They do not involve the analysis of specimens taken from the body.
Therefore, these devices fall under the category of surgical instruments and navigation accessories, not In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
TELIGEN Navigation Ready Instruments:
The TELIGEN System is indicated to provide minimally invasive access, visualization, illumination, magnification and discectomy of the surgical area of the spine.
The TELIGEN Access Probe and TELIGEN Clear are Navigation Ready Instruments and when used with the compatible Universal Navigation Adaptor Set (UNAS) are intended to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. The navigation feature is used in surgical spinal procedures, in which:
· the use of stereotactic surgery may be appropriate, and
· reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated tracking arrays.
These procedures include but are not limited to spinal fusion.
TELIGEN Clear and TELIGEN Access Probe, when used with UNAS Navigation Rings, can be precalibrated with:
- · the VELYS Spine System using the VELYS Spine Instrument Arrays,
- · the Brainlab Navigation System using the UNAS Arrays.
TELIGEN Access Probe in conjunction with UNAS can also be manually calibrated with other navigation systems, using tracking arrays supplied by the navigation system manufacturer.
The TELIGEN Access Probe is indicated for stimulation of peripheral motor nerves, including spinal nerve roots, for location and identification during surgery.
Discectomy Navigation Ready Instruments:
The Discectorny Navigation Ready Instruments when used with the compatible Universal Navigation Adaptor Set are intended to assist the surgeon in locating anatomical structures to facilitate disc space preparation, including discectomy or bony resection. These are indicated for use in surgical spinal procedures, in which:
- · the use of stereotactic surgery may be appropriate, and
· reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data-based model of the anatomy using a navigation system and associated navigation arrays.
These procedures include but are not limited to spinal fusion. The Discectomy Navigation Ready Instruments can be pre-calibrated with the VELYS Spine System (only for TELIGEN Graft Delivery Cannula and the curettes) as well as the Brainlab Navigation System.Universal Navigation Adaptor Set:
The Universal Navigation Adaptor Set (UNAS) is intended for use with the compatible DePuy Synthes Navigation Ready Instruments to assist the surgeon in locating anatomical structures in either open or percutaneous procedures. These are indicated for use in surgical spinal procedures, in which:
· the use of stereotactic surgery may be appropriate, and
· reference to a rigid anatomical structure, such as the pelvis or a vertebrae can be identified relative to the acquired image (CT, MR, 2D fluoroscopic image or 3D fluoroscopic image reconstruction) and/or an image data based model of the anatomy using a navigation system and associated tracking arrays.
These procedures include but are not limited to spinal fusion. The DePuy Synthes Navigation Ready Instruments, when used with UNAS, can be:
· pre-calibrated with the VELYS Spine System using VELYS Spine System Instrument Arrays,
- · pre-calibrated and/or manually calibrated with the Brainlab Navigation System,
where other navigation systems require manual calibration and tracking arrays supplied by the navigation system manufacturer.
