Intended Use

The ViziShot 2 FLEX has been designed to be used with ultrasound endoscopes for ultrasound guided fine needle aspiration (FNA) and fine needle biopsy (FNB) of submucosal and extramural lesions of the tracheobronchial tree. Do not use this device for any purpose other than its intended use.

Device Description

The subject device, ViziShot 2 FLEX is a single use aspiration needle to be used in conjunction with compatible ultrasound endoscopes for ultrasound guided fine needle aspiration (FNA) and fine needle biopsy (FNB) of submucosal and extramural lesions of the tracheobronchial tree.

The subject 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. The device is a single-use sterile device.

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 2 FLEX is available in one model only (NA-U403SX-4019), with a needle size of 19 gauge (19G). The two required accessories, the Adapter Biopsy Valve and the Merit Syringe with Stopcock, are packaged with the ViziShot 2 FLEX.

AI/ML Overview

The ViziShot 2 FLEX is a single-use aspiration needle used with ultrasound endoscopes for ultrasound-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) of lesions in the tracheobronchial tree. The device is identical to a previously marketed device (K163469) in formulation, processing, sterilization, and geometry, with the proposed addition of "fine needle biopsy (FNB)" to its Indications for Use, which aligns with the primary predicate device (Cook Echotip Procore Endobronchial High Definition Ultrasound Biopsy Needle, K160229).

Here's the breakdown of its acceptance criteria and the study conducted to prove it:

1. Acceptance Criteria and Reported Device Performance

Acceptance Criteria / TestReported Device Performance
Biocompatibility (per ISO 10993-1, -4, -5, -10, -11, USP , USP )All patient-contacting surfaces were tested and found to be biocompatible, demonstrating compliance with the specified international and national standards. The device is classified as external communicating, blood path (indirect), and limited duration (

§ 874.4680 Bronchoscope (flexible or rigid) and accessories.

(a)
Identification. A bronchoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the bronchoscope and is intended to examine or treat the larynx and tracheobronchial tree. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel or flexible plastic. This generic type of device includes the rigid ventilating bronchoscope, rigid nonventilating bronchoscope, nonrigid bronchoscope, laryngeal-bronchial telescope, flexible foreign body claw, bronchoscope tubing, flexible biopsy forceps, rigid biopsy curette, flexible biopsy brush, rigid biopsy forceps, flexible biopsy curette, and rigid bronchoscope aspirating tube, but excludes the fiberoptic light source and carrier.(b)
