The description details a mechanical device for tissue sampling and does not mention any computational or algorithmic components indicative of AI/ML.
No.
The device is used to obtain tissue samples for diagnostic purposes (cytopathological or microbiological examination), not to treat a condition.
Yes
Explanation: The device is used to collect tissue samples (biopsy) for cytopathological or microbiological examination, which are diagnostic procedures to identify the nature of lesions.
No
The device description clearly outlines physical components (handle, sheath, needle, stylet) and describes a mechanical process for tissue aspiration. It is a physical medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of a disease or condition.
- ViziShot FLEX Function: The ViziShot FLEX is a sampling device. Its primary function is to collect a tissue sample (biopsy) from the tracheobronchial tree.
- Purpose of the Sample: The description explicitly states that the removed tissue is then prepared for cytopathological or microbiological examination and testing. This examination and testing is where the diagnostic process occurs, and it is performed on the sample, not by the ViziShot FLEX itself.
The ViziShot FLEX is a tool used to obtain the specimen that will then be used in an in vitro diagnostic process. It is not the diagnostic device itself.

Device Description
The ViziShot FLEX is intended for use with compatible ultrasound endoscopes for Transbronchial Needle Aspiration (TBNA) of submucosal and extramural lesions of the tracheobronchial tree. The device is supplied sterile and intended for single patient use.
The device consists of a handle, sheath, needle, and stylet. The sheath and needle are attached to the handle, and the removable stylet is located within the needle. Note that although the device has a component called a needle, the device is often referred to as a needle as well.
Prior to a procedure, the flexible catheter portion is inserted into a bronchoscope's working channel (2.2mm) and advanced forward until fully inserted. The handle is then affixed to the channel port of the endoscope via a lever mechanism that locks onto the Adapter Biopsy Valve. The needle is advanced through the bronchoscope to the sampling site while visualizing both the target and the needle in real time with ultrasound. The handle facilitates advancement of the needle during puncture of the targeted biopsy site. The sample is obtained by penetrating the lesion with the needle while applying suction at the proximal end of the handle. After completing the sampling, the vacuum from the syringe is released to atmosphere, the handle unlocked from the bronchoscope, and the catheter and needle pulled out from the working channel. The removed tissue can then be prepared for cytopathological or microbiological examination and testing.
The ViziShot FLEX is available in one model only (NA-U402SX-4019), with a needle size of 19 gauge (19G). The two required accessories, the Olympus Adapter Biopsy Valve and the Merit Syringe with Stopcock, are packaged with the ViziShot FLEX.
