Intended Use

LaparoGuard is indicated for use with compatible laparoscopic devices. LaparoGuard can be used in general laparoscopy wherever a laparoscope is indicated for use.

Device Description

LaparoGuard allows surgeons to virtually annotate a safe anatomical volume ("safe zone") inside the body cavity of a patient during a laparoscopic surgery. A compatible laparoscope, such as the ConMed IM3300 (K031098), captures video feed that is processed by LaparoGuard, which tracks surgical instruments and the safe zone boundaries to display a real-time overlay on a compatible laparoscope monitor, such as the Stryker Vision Elect 21" (K081995). Surgical teams receive visual and auditory notifications throughout the procedure whenever a tracked instrument has exited the safe zone.

AI/ML Overview

The provided text describes the LaparoGuard device and its substantial equivalence to a predicate device, focusing on non-clinical testing and software validation. However, it does not include detailed information regarding clinical study results, acceptance criteria for performance metrics (like sensitivity, specificity, accuracy), or specifics about a test set and its ground truth establishment involving experts.

Therefore, I cannot populate the table or answer questions 2-9 from the provided input, as that information is not present.

Here's what can be extracted based on the provided text:

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

The document mentions non-clinical testing, but does not provide specific acceptance criteria or reported performance values for metrics typically found in clinical studies (e.g., accuracy, sensitivity, specificity, etc. related to its primary function of "safe zone" monitoring). It does state adherence to standards for accuracy, but not the specific thresholds or measured performance of the device against those thresholds.

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

This information is not provided. The document mentions "system integration testing using anatomical phantoms" but does not detail a clinical test set with human data.

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 information is not provided.

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

This information is not provided.

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

There is no mention of an MRMC study or AI assistance to human readers. The device is purely a monitoring system providing visual and auditory notifications.

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

The device itself is a "standalone" system in its monitoring function, providing alerts to the surgeon. The "system accuracy using an accuracy measurement phantom" and "system integration testing using anatomical phantoms" could be considered standalone performance tests in a controlled environment, but detailed results and specific metrics are not given.

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

For the non-clinical testing mentioned (accuracy measurement phantom, anatomical phantoms), the ground truth would be based on the known, precisely defined physical properties of these phantoms. No mention of expert consensus, pathology, or outcomes data is made for establishing ground truth for any performance claims.

8. The sample size for the training set

This information is not provided. The document focuses on verification and validation of the software and system, not on a machine learning model's training set.

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

This information is not provided.

§ 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.
