The PENTAX Medical Video Bronchoscopes (EB Family) have been designed to be used with a PENTAX Medical Video Processor (including Light source), documentation equipment, video monitor, endo-therapy accessories (such as biopsy forceps) and other ancillary equipment for endoscopy and endoscopic surgery within the airways and tracheobronchial tree.

The PENTAX Medical Video Naso-Pharyngo-Laryngoscope (VNL-1570STK) is designed to be used with a PENTAX Medical video processor, light source, documentation equipment, display monitor, endoscopic accessories, and other ancillary equipment and intended to provide optical visualization (via a video monitor) of, and therapeutic access to, nasal, pharyngeal, laryngeal and the upper airway anatomy.

The EB-1970UK, Ultrasound Video Bronchoscope, is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Pulmonary Track including but not restricted to the organs, tissues, and subsystems: Nasal Passage, Pharynx, Trachea, Bronchial Tree (including access beyond the stem), and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for procedure are observed in adult and pediatric populations.

Device Description

The PENTAX Medical Video Bronchoscopes, Video Naso-Pharyngo-Laryngoscope and Ultrasound Video Bronchoscope are identical to their respective predicate devices with the sole exception being that epoxy has been added to the suction nipple of the subject devices to prevent loosening of the suction nipple. There are no other changes to the design, specifications, or technological characteristics of the predicate devices as described in K131028 (EB family), K162151 (VNL-1570STK) and K081518 (EB-1970UK).

Both the Bronchoscopes and Naso-Pharyngo-Laryngoscope are composed of an Insertion Portion, Control Body, PVE Connector and Light Guide Plug. In addition to the parts above, the Ultrasound Video Bronchoscope has an Ultrasound Umbilical Connector.

All the Bronchoscopes, Naso-Pharyngo-Laryngoscope and Ultrasound Video Bronchoscope are reusable devices initially supplied non-sterile to the user and require the user to reprocess prior to initial use and between each use. All the Bronchoscopes, Naso-Pharyngo-Laryngoscope and Ultrasound Video Bronchoscope are used with compatible PENTAX Medical Video Processors.

AI/ML Overview

This document describes a 510(k) premarket notification for PENTAX Medical Video Bronchoscopes, PENTAX Medical Video Naso-Pharyngo-Laryngoscope, and PENTAX Medical Ultrasound Video Bronchoscope. The purpose of the 510(k) is to obtain clearance for the addition of epoxy to the suction nipple of these devices to prevent loosening.

Here's a breakdown of the information requested:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state numerical acceptance criteria in the typical "pass/fail" format often seen for performance metrics like sensitivity or specificity. Instead, the acceptance criterion for the modification is implied: the epoxy must sufficiently prevent the loosening of the suction nipple under specified stress conditions.

Acceptance Criterion (Implied)	Reported Device Performance
Adequate adhesive strength to prevent loosening of suction nipple	"The results indicate that the subject epoxy has adequate adhesive strength to prevent looseness of the suction nipple under all stress conditions specified by the protocol." "The performance data indicates that the subject devices with epoxy applied to the suction nipple have adequate adhesive strength to prevent looseness of the suction nipple under stress conditions."

2. Sample sized used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

The document does not specify the sample size (e.g., number of devices tested) for the performance testing. It also does not provide information about the country of origin or whether the study was retrospective or prospective.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

This device is not an AI/ML device that requires expert-established ground truth. The performance testing described is engineering-based, focusing on the mechanical integrity of a component (suction nipple with epoxy).

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable for this type of engineering performance testing. No adjudication method concerning expert consensus or disagreements is described.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is not an AI-assisted device, and no MRMC study was performed.

6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done

Not applicable. This is not an AI/ML device. The "standalone" performance here refers to the device's mechanical integrity, which was tested.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" in this context is the actual physical state of the suction nipple (i.e., whether it remains securely attached or loosens). This was determined by controlled mechanical stress testing.

8. The sample size for the training set

Not applicable. This is not an AI/ML device, so there is no training set.

9. How the ground truth for the training set was established

Not applicable. There is no training set for this device.

V. INDICATIONS FOR USE

There are no changes to the Indications for Use for the subject devices. The sole purpose of this 510(k) is to obtain clearance for the addition of epoxy to the suction nipple of the scopes.

VI. COMPARISON OF TECHNOLOGY CHARACTERISTICS WITH THE PREDICATE

The subject devices are identical to the predicate devices with the exception of the addition of epoxy to prevent loosening of the suction nipple of the subject devices. The subject devices have the same fundamental technology and operating principles as the predicate device, including the same intended use and technological characteristics, such as Insertion Portion, Control Body and fiberoptics illumination. There are no differences in specifications, including, but not limited to, depth of field, distal end width, insertion tube width, instrument channel width, and total length. The sole difference between the subject and predicate devices is the addition of epoxy to the suction nipple of the scopes. This modification does not impact the intended use and does not raise different questions of safety and effectiveness.

VII. PERFORMANCE DATA

The addition of epoxy to the suction nipple of the EB, VNL and EB-1970UK scopes do not affect the biocompatibility, reprocessing, electrical safety, electromagnetic compatibility, or software

{9}------------------------------------------------

verification and validation.

Performance testing of the suction nipple sub-assembly under stress conditions utilizing epoxy materials was conducted to determine the force (torque) required to loosen the subassembly. The results indicate that the subject epoxy has adequate adhesive strength to prevent looseness of the suction nipple under all stress conditions specified by the protocol.

VIII. CONCLUSION

The subject and predicate devices are identical with the exception of the addition of epoxy to the suction nipple. The subject devices have the same intended use and technological characteristics as the predicate devices. There are no other changes to the design of the subject devices.

The performance data indicates that the subject devices with epoxy applied to the suction nipple have adequate adhesive strength to prevent looseness of the suction nipple under stress conditions. The data provided in this 510(k) Premarket Notification support the equivalence of the subject and predicate devices.

Regulation Number and Section
