The LIA-1 Catheter is intended for use through a compatible bronchoscope in the tracheobronchial tree for Optical Coherence Tomography (OCT) guided Fine Needle Aspiration (FNA) and Fine Needle Biopsy (FNB) of endobronchial lesions, peripheral lung nodules, and lung masses. The device collects real-time two-dimensional, cross-sectional depth images which are visualized for evaluation of human tissue microstructure on the LIA Console.
Do not use this device for any purpose other than its intended use. This device is intended to provide an image of tissue microstructure in the tracheobronchial tree and parenchyma. 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.
Indications for use as stated in the FDA summary.
