Intended Use

The LIA Console is indicated for use as an imaging tool in the evaluation of human tissue microstructure in the tracheobronchial tree by providing two-dimensional, cross-sectional, real-time depth visualization using Optical Coherence Tomography (OCT). 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

Device Story

LIA Console is a mobile Swept-Source Optical Coherence Tomography (SS-OCT) imaging system used in conjunction with the LIA-1 Catheter. The system includes a 24-inch touch display, a Catheter Driving Unit (CDU) with a rotary motor for 360-degree imaging, a stabilizing Catheter Driving Arm (CDA), and an image engine containing a laser source and computing unit. The device transmits infrared light to tissue via the catheter and processes backscattered optical signals to generate real-time, cross-sectional 2D images of tissue microstructure. Operated by clinicians in a clinical setting, the system provides visual feedback to assist in endobronchial biopsy procedures. The output is displayed on the console monitor for real-time evaluation of tissue structure. The device benefits patients by providing high-resolution visualization of the tracheobronchial tree to support procedural guidance.

Clinical Evidence

No human clinical data. Evidence includes bench testing (OCT sensitivity, resolution, NURD, optical power, metalens profile) and a GLP porcine study (n=2) evaluating 32 fiducial lung nodules. The porcine study demonstrated 100% biopsy success rate and real-time imaging capability in airways 1mm-10mm in diameter with no complications.

Technological Characteristics

Swept-Source OCT (SS-OCT) imaging system. Components: mobile console, articulating Catheter Driving Arm, Catheter Driving Unit with Fiber Optical Rotary Joint (FORJ). Laser: 1300 nm center wavelength, Class 1M Laser Product (IEC 60825-1). Connectivity: proprietary OCTICA software. Electrical safety: ANSI/AAMI ES 60601-1, IEC 60601-1-2. Ingress protection: IPX1. Service life: 3 years.

Indications for Use

Indicated for use as an imaging tool for evaluation of human tissue microstructure in the tracheobronchial tree. Not indicated for diagnostic analysis or differentiation of normal versus abnormal tissue.

5. Caster: Four caster wheels installed at the base provide mobility for the LIA Console. Each caster is equipped with a brake that can lock the LIA Console in place as needed.
6. OCTICA Software: A proprietary GUI-based software that controls data acquisition, rotary motor and other hardware components to enable real-time OCT imaging of tissue microstructure.

## Indications for Use [Intended Use 807.92(a)(5)]:

The LIA Console is indicated for use as an imaging tool in the evaluation of human tissue microstructure in the tracheobronchial tree by providing two-dimensional, cross-sectional, real-time depth visualization using Optical Coherence Tomography (OCT). 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.

## Technological Characteristics 807.92(a)(6):

The LIA Console is an imaging tool for the evaluation of human tissue microstructure using Optical Coherence Tomography (OCT). The system is not intended for diagnostic differentiation. Swept Source Optical Coherence Tomography (SS-OCT) is the method for real-time cross-sectional imaging, supporting tissue evaluation.

The LIA Console consists of (i) an imaging console, (ii) a catheter driving arm, and (iii) proprietary LIA Real-Time Imagine Software used to acquire, process, and visualize OCT images. It is used in conjunction with a compatible LIA-1 Catheter during the endobronchial biopsy procedure.

The mobile imaging console contains a light source, interferometer, and computing unit. It processes optical signals received from the LIA-1 Catheter to generate and display real-time images on the monitor.

The Catheter Driving Arm (CDA) includes an articulating stabilization arm and a driving module including an optical receptacle to which the LIA-1 is connected. The driving module drives the imaging stylet to form a 360-degree 2D image. The arm stabilizes the imaging probe throughout the procedure.

The Catheter Driving Unit (CDU) serves as the optomechanical interface between the LIA-1 Catheter and the imaging engine. It includes a Fiber Optical Rotary Joint (FORJ) that transmits optical signals to the LIA-1 Catheter and receives the backscattered signal after interaction with tissue. The FORJ, in conjunction with a motor, also rotates LIA-1 Catheter's optical probe to generate a 360-degree image.

As shown in Table 1 below, the LIA Console is substantially equivalent to the predicate devices, as it has the same intended use and its technological characteristics are similar to, and substantially equivalent to, the cited predicates.

raising no new issues of safety or effectiveness. Tests included, but not limited to, OCT sensitivity characterization, service life, fluid ingress, lateral and axial resolution, NURD measurement, optical power efficiency, metalens field profile analysis. All testing passed the acceptance criteria.

# Summary of Pre-clinical Tests 807.92(b)(1):

A GLP porcine study with Fiducial Lung Nodule (FLN, ≤20mm) was conducted to evaluate human tissue microstructure in the tracheobronchial tree. Thirty two FLNs were administrated into airway system of two pigs (16 FLNs per animal). The data show that LIA System (LIA Console and LIA-1 Catheter) can provide real-time imaging of tissue microstructure in the tracheobronchial tree with diameters ranging from 1mm-10mm. Additionally, the data show the biopsy success rate using the LIA System was 100% for all 32 FLNs. There were no complications found during the study.

Therefore, the GLP porcine study concludes LIA System is substantially equivalent to the predicate device and meets the intended use.

Clinical performance testing was not required as simulated use validation demonstrated intended use performance.

# Conclusion 807.92(b)(3):

LIA Console and the predicate device, NvisionVLE® Imaging System (K182616) are both devices that "project a beam into body tissue to determine the depth or location of the tissue interfaces" according to regulation 892.1560. Both devices are specifically Optical Coherence Tomography (OCT) imaging systems within product code NQQ.

The indications for use and key technological characteristics are substantially equivalent employing swept source Optical Coherence Tomography (SS-OCT) imaging modalities and ensuring comparable real-time tissue visualization for clinical applications

LIA Console was evaluated for electrical, optical, mechanical, and EMC safety and found to conform to applicable mandatory medical device safety standards.

The differences between the devices do not raise new and/or different questions of safety and effectiveness. LIA Console conforms to applicable safety standards and performance data in a simulated clinical workflow (including in K251402, LIA-1 Catheter) validates the intended use. The predicate comparison table (Table 1) and performance testing provided in this 510(k) is sufficient to demonstrate that the LIA Console is substantially equivalent to the legally marketed predicate device, NvisionVLE® Imaging System cleared under 510(k) K182616.
