AI/ML Overview

The SonoScape Medical Corp. HD-550 Video Endoscope System (K222020) is found to be substantially equivalent to its predicate device (K211882) based on non-clinical performance data. No clinical study was performed.

Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a substantial equivalence determination based on an identical predicate device, the "acceptance criteria" are effectively the specifications and performance of the predicate device, and the "reported device performance" is the claim that the proposed device is identical to the predicate device in these aspects.

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

  • Sample size for the test set: Not applicable. The submission states, "No clinical study is included in this submission." The evaluation relies on the equivalence of the proposed device to the predicate device, which itself would have had its performance demonstrated through testing. The current submission focuses on non-clinical tests to demonstrate that the proposed device is identical to the predicate device in all relevant aspects, except for a reprocessing change.
  • Data provenance: Not explicitly stated for the non-clinical tests. However, the manufacturer is Sonoscape Medical Corp. in Shenzhen, Guangdong, China. The non-clinical tests (electrical safety, EMC, performance, biocompatibility) are typically performed by the manufacturer or accredited labs on their behalf. The liquid chemical sterilization test reports were submitted to support the reprocessing change.

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)

Not applicable. No clinical study with a "test set" requiring expert ground truth was conducted for this specific submission. The submission is based on substantial equivalence to a predicate device.


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

Not applicable. No clinical study requiring adjudication of a test set was conducted for this submission.


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 device is an endoscope system, not an AI-assisted diagnostic tool for interpretation of images by human readers. The document makes a note that "The prospective clinical value of the enhanced imaging modes has not been demonstrated, and no clinical claims are made" regarding the enhanced imaging modes (EWL, SFI, VIST).


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

Not applicable. This is not an algorithm-only device. It is a medical device system (endoscope, image processor, light source) used by a human operator.


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

Not applicable. No clinical study with a "ground truth" was conducted for this submission. The demonstration of performance relies on compliance with recognized standards (IEC, ISO) and comparison of specifications with a legally marketed predicate device.


8. The sample size for the training set

Not applicable. This is not a machine learning or AI-driven submission that would involve a "training set."


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

Not applicable. As above, no training set was used.

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.
