Intended Use

The Single Use Hemoclip Device is indicated for endoscopic clip placement within the gastrointestinal tract for the purpose of: (1) endoscopic marking, (2) hemostasis for (a) mucosal / sub-mucosal defects < 3cm, (b) bleeding ulcers, (c) polyps < 1.5cm in diameter, (d) diverticula in the colon, (3) as a supplementary method, closure of GI tract luminal perforations <20mm that can be treated conservatively (4)the age of the intended population for the device is for patients who are 18 and older.

Device Description

The proposed device Single Use Hemoclip is a sterile, single-use endoscopic clipping device, intended to be used for endoscopic marking, hemostasis for mucosal/submucosal defects in digestive tract. It consists of two main components, delivery system and clip assembly. And it is offered in different dimensions.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device (Single Use Hemoclip) and demonstrates its substantial equivalence to predicate devices. However, the document does not contain information about the acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML powered medical device, which the provided prompt seems to be specifically asking for.

The acceptance criteria typically outlined in AI/ML medical device submissions (as per the prompt's structure) would include metrics like sensitivity, specificity, AUC, and performance targets against "ground truth" established by experts. The provided document instead focuses on equivalence testing for a physical medical device (a hemoclip), detailing mechanical and biological testing to ensure its safety and performance.

Therefore, I cannot fulfill the request to provide:

  1. A table of acceptance criteria and reported device performance: Because the document does not define such criteria or report AI/ML performance metrics.
  2. Sample size and data provenance for the test set: Not applicable for a physical device.
  3. Number of experts and qualifications for ground truth: Not applicable for a physical device.
  4. Adjudication method for the test set: Not applicable for a physical device.
  5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable for a physical device.
  6. Standalone (algorithm-only) performance: Not applicable as there is no algorithm.
  7. Type of ground truth used: Not applicable.
  8. Training set sample size: Not applicable.
  9. How ground truth for training set was established: Not applicable.

The "Performance data" section in the document (Page 8, Item 7) lists bench tests conducted on the Single Use Hemoclip, which are relevant for a physical device, but not for an AI/ML driven one:

  • Dimensional verification
  • Mechanical Integrity of Clip Assembly
  • Clamping Strength Testing
  • Tensile Strength Testing
  • Release Force Testing
  • Rotation Testing

The conclusion states that "The testing performed demonstrated that the proposed and predicate delivery systems are equivalent." This is the "proof" for this specific device, based on physical and material properties, not AI/ML performance.

In summary, the provided document relates to the 510(k) clearance of a physical medical device and thus does not contain the information requested about AI/ML device acceptance criteria and performance studies.

Dear Lucius Long:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

{1}------------------------------------------------

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
