The description focuses on the OCT imaging technology and a laser marking function. There is no mention of AI or ML in the intended use, device description, or performance studies. The software is described as processing and visualizing images, which is standard for imaging systems and does not inherently imply AI/ML.
No
The device is primarily an imaging tool for visualizing tissue microstructure, providing diagnostic information rather than directly treating a condition. While it has a marking function, this is to aid further evaluation, not to deliver therapy.
No
The "Intended Use / Indications for Use" section explicitly states, "The safety and effectiveness of this device for diagnostic analysis (i.e. differentiating normal versus specific abnormalities) in any tissue microstructure or specific disease has not been evaluated." It is indicated for use as an imaging tool, not for diagnosis.
No
The device description explicitly lists multiple hardware components, including a console, probes, and an inflation system, in addition to the software.
Based on the provided information, the NvisionVLE Imaging System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue samples) taken from the human body to provide information for diagnosis, monitoring, or screening.
- NvisionVLE Function: The NvisionVLE Imaging System directly images human tissue in situ (within the body) using optical coherence tomography. It does not analyze samples removed from the body.
- Intended Use: The intended use explicitly states it's an "imaging tool in the evaluation of human tissue microstructure" and provides "real-time depth visualization." It also explicitly states that the "safety and effectiveness of this device for diagnostic analysis (i.e. differentiating normal versus specific abnormalities) in any tissue microstructure or specific disease has not been evaluated." This further reinforces that its primary function is imaging and marking, not providing a diagnosis based on analysis of a sample.
While the device provides information about tissue microstructure that a clinician might use in their diagnostic process, the device itself is not performing the diagnostic analysis on a sample. It's providing an image of the tissue in its natural state.

Device Description
The NinePoint Medical NvisionVLE® Imaging System is a high-resolution volumetric imaging system based on optical coherence tomography (OCT). In an analogous fashion to ultrasound imagery, OCT images are formed from the time delay and magnitude of the signal reflected from the tissue of interest. The NvisionVLE Imaging System employs an advanced form of OCT known as swept-source OCT (SS-OCT), or Optical Frequency Domain Imaging (OFDI), in combination with a scanning optical probe to acquire high-resolution, cross-sectional, real-time imagery of tissue called Volumetric Laser Endomicroscopy (VLE).
In addition to the imaging capability, the device provides a means of marking areas of tissue with an additionally integrated 1470nm laser. The ability to create temporary laser marks directly on tissue enables a clinician to place visual reference marks on tissue regions of clinical interest immediately following their identification via VLE.
The device consists of the following five main components and accessories: (i) a mobile NvisionVLE Console with an integrated computer and two touch-screen interfaces; (ii) proprietary NvisionVLE Software used to acquire, process, and visualize VLE images; (iii) a single-use, sterile NvisionVLE Marking Probe that is inserted through the working channel of an endoscope; (iv) a single-use, sterile NvisionVLE Inflation System that is used to inflate the Marking Probe's balloon to facilitate placement; and (v) a Probe Lock Accessory to prevent longitudinal motion of the Marking Probe within the endoscope. The first four components provide the previously-cleared (K143678) VLE imaging functionality of the NvisionVLE Imaging System. The device consists of a Laser Marking Unit and a Hand Controller as part of the NvisionVLE Console, and updated NvisionVLE Software for the laser marking functionality. A Probe Lock Accessory is also provided to the user as a convenience to help stabilize the Marking Probe during laser marking.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A series of bench and animal tests have been conducted to assess the performance and safety of the device. Acute and short-term chronic animal studies confirmed feasibility of the laser marking method and the device in a simulated clinical environment. Laser doses of power and time were evaluated to find the optimum parameter setting to achieve marks that were both visible under VLE and White Light Endoscopy, but also deemed safe and did not result in injury. In addition, a series of bench testing was performed to establish the accuracy of marking areas of interest.
Clinical testing evaluated the safety and efficacy of this technology, confirming the use of the laser marking functionality for aiding a physician to further evaluate tissue regions of interest as identified on the VLE image.

7. Substantial Equivalence:
The NvisionVLE Imaging System has the same intended use and similar indications, principles of operation, and technological characteristics as the predicate and reference devices. The minor differences in the NvisionVLE Imaging System technological characteristics do not raise any new or different questions of safety or effectiveness. Specifically, the primary predicate device and the proposed device have nearly the same technological characteristics. The main technological difference between the proposed device and the primary predicate imaging system is the addition of a marking laser, the Laser Marking Unit (LMU) subsystem, which is used to mark the tissue and is controlled via a Hand Controller. All appropriate laser safety controls have been incorporated per IEC 60825-1. The second predicate, the QUANTA laser, is the same type of laser as that added to the subject device in the Laser Marking Unit (LMU) subsystem and has the same classification and wavelength; Notably, the marking laser in the subject device has a power output that is far less (milliWatts versus Watts) than the power employed by the predicate to cut, ablate, or vaporize soft tissue. The marking laser employs only enough power to denature the soft tissue to cause a very slight degree of thermal injury.
The laser marking feature of the proposed device does not affect the intended use or risks of using the imaging tool, nor does the imaging tool affect the performance or risk profile of the marking laser. The laser marking feature is a convenience component that is added to the predicate imaging tool to create the new device, with the intended use of the new device still being that of the imaging tool, as discussed above.
Performance data demonstrates that the NvisionVLE Imaging System is as safe and effective as the predicate and reference devices. Thus, the NvisionVLE Imaging System is substantially equivalent.
