The EG-3870UTK, Ultrasound Video Gastroscope, is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Track including but not restricted to the organs, tissues, and subsystems: Esophagus, Stomach, Duodenum, Small Bowel, and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for procedure are observed in adult and pediatric patient populations.
Diagnostic Ultrasound imaging or fluid flow analysis of the human body as follows: Endoscopy
PENTAX EG-3870UTK Ultrasound Video Gastroscope + HI VISION PREIRUS are the endoscopic ultrasound system consists of an ultrasound endoscope with a curved linear array type ultrasound transducer, video processor, and Hitachi ultrasound scanner. This modified new system configuration is to work together with the already cleared latest Hitachi HI VISION PREIRUS Diagnostic Ultrasound Scanner (K093466).
The provided text is a 510(k) summary for a medical device called "PENTAX EG-3870UTK Ultrasound Video Gastroscope (Curved Linear Array Type) + HI VISION PREIRUS". It describes a modification to an already cleared system. This document is a regulatory submission for premarket notification, not a clinical study report detailing acceptance criteria and performance data for a device.
Therefore, I cannot provide the requested information about acceptance criteria and device performance based on the provided text for the following reasons:
- This is a Special 510(k) submission for a modification, not a de novo clearance or a typical 510(k) requiring detailed performance data against acceptance criteria. The submission explicitly states: "There are no software or hardware changes between the PENTAX EG-3870UTK Ultrasound Video Gastroscope subject and predicate device in connecting with the new Hitachi HI VISION PREIRUS Diagnostic Ultrasound Scanner. In addition, there are no change in technology, including features, materials, and principles of operation." The modification is simply a change in the ultrasound scanner used with the endoscope.
- The justification for clearance is "substantial equivalence" to a predicate device, not demonstration of meeting specific performance acceptance criteria through a clinical study. The document states: "The system configuration modification does not impact the intended use, safety and/or effectiveness. The modified system configuration has been verified and validated according to the company's design control activities as certified in this Special 510(K) Submission's declaration of conformity with design control to ensure the compatibility between the PENTAX EG-3870UTK Ultrasound Video Gastroscope and the HITACHI HI VISION PREIRUS Ultrasound Scanner." This implies compatibility testing, not a formal clinical trial with acceptance criteria for diagnostic performance.
- No clinical study to demonstrate "device performance" in terms of sensitivity, specificity, accuracy, etc., is described. The document focuses on the equivalence of the modified system.
In summary, the provided document does not contain the information required to populate the requested table and answer the questions about acceptance criteria, study details, sample sizes, ground truth, experts, or comparative effectiveness studies. This type of information is typically found in full clinical study reports, which are usually not part of a Special 510(k) for a system configuration change like this.
§ 876.1500 Endoscope and accessories.
(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
