## Indications for Use

The ClearTip TBNA Type is intended for Ultrasonically Guided Fine Needle Aspiration, (FNA) of submucosal and extraluminal lesions of the Tracheobronchial Tree.

## Device Story

ClearTip TBNA Type is a manually operated endoscopic instrument for obtaining tissue specimens from the tracheobronchial tree. The device consists of a handle unit, insertion part, syringe, stopcock, and connector. It is designed to pass through the working channel of an endoscope. During clinical use, the physician operates the device to perform fine needle aspiration of submucosal or extraluminal lesions under ultrasonic guidance. The device is supplied sterile for single-patient use. By enabling targeted tissue sampling, it assists in the diagnosis of lesions within the tracheobronchial tree.

## Clinical Evidence

No clinical data. Substantial equivalence is supported by non-clinical bench testing, including appearance, dimensions, operability, elasticity, flexural strength, pull-out, tensile force, insertion/withdrawal force, needle extraction/retraction, and needle slider performance.

## Technological Characteristics

Manual endoscopic instrument; materials include PEEK, Nitinol, and PTFE. Dimensions: 19G/22G needles; sheath lengths 746.5-774.5 mm. Compatible with minimum 2.2 mm accessory channels. Sterilized via Ethylene Oxide (EO). Single-use, non-powered device.

## Regulatory 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.

## 7.2. Substantial Equivalence Discussion

The reference device (unmodified device) manufactured by our company covers the indication for use as the subject device.

The differences between the subject device and the unmodified device are limited to the handle shape, the addition of one additional needle gauge option (19 gauge), the sheath length, and the total needle length. The modified handle design is similar to that of the primary predicate device, K190239.

To evaluate whether these differences affect the safety or effectiveness of the subject device, comparative performance testing was conducted between the subject device and the predicate device. The testing addressed the modified dimensional characteristics. The results demonstrated that the subject device performs comparably to the unmodified device and meets the same acceptance criteria.

Based on the test results, we determine that the subject device is substantially equivalent to the predicate device.

## 8. Non-clinical Tests

The following tests were performed on the subject device and the test results support that the subject device is substantially equivalent to the predicate devices.

- Appearance

{7}

- Dimensions
- Operability
- Elasticity
- Flexural strength

- Tensile force tests
- Insertion and Withdrawal Force
- Needle Extraction/Retraction
- Needle Slider Performance

9. Conclusion:

Based on the information provided herein and the test results, we conclude that the subject device is substantially equivalent to its predicate device.
