Device Description

The Instinct Plus Endoscopic Clipping Device is a sterile, single use metallic clip used for tissue approximation and hemostasis in the gastrointestinal tract. The metallic clip is 14.4 mm long and has an opening span of 16 mm. The clip is preloaded on a 230 cm long introducer comprised of a coated coil spring, drive wire and deployment handle. The clip may be deployed to the site of interest using a straight viewing flexible endoscope with a minimum accessory channel of 2.8 mm, or side viewing flexible endoscope with a minimum accessory channel of 4.2 mm. The clip can be rotated for positioning by rotating the handle of the introducer and may be reopened and closed up to five times prior to deployment.

The Instinct Plus Endoscopic Clipping Device is supplied sterilized by ethylene oxide gas in a peel-open package and intended for one-time use. The product is packaged with one-year shelf life.

AI/ML Overview

This is a 510(k) premarket notification for the Instinct Plus Endoscopic Clipping Device. The document claims substantial equivalence to two predicate devices: the K151802 Resolution™ 360 Clip and the K132809 Instinct Endoscopic Hemoclip.

Here's an analysis of the acceptance criteria and supporting study information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document lists "design input requirements" that performance testing was conducted to meet. These essentially serve as acceptance criteria. However, explicit numerical or categorical acceptance values for each criterion are not provided in the summary. Instead, it generally states that the device "met the design input requirements."

Table: Acceptance Criteria and Reported Device Performance

Acceptance Criterion (Design Input Requirement)Reported Device Performance
1. SterilityMet design input requirements
2. PackagingMet design input requirements
3. BiocompatibilityMet design input requirements
4. Advance device into the GI tract through a compatible endoscopeMet design input requirements
5. Position and approximate target siteMet design input requirements
6. Deploy clip onto targeted GI tissueMet design input requirements
7. Removal of device from the endoscopeMet design input requirements
8. Force of clip retention at tissueMet design input requirements
9. Force of clip compression at tissueMet design input requirements
10. Strength of clip assemblyMet design input requirements
11. Strength of clip housingMet design input requirements
12. MRI TestingMet design input requirements
13. Corrosion testingMet design input requirements
14. Force to deploy clip on tissue handleMet design input requirements
15. Strength of Introducer Coil CathMet design input requirements
16. Strength of Handle and DrivewireMet design input requirements

2. Sample Size Used for the Test Set and Data Provenance:

The document is a 510(k) summary and does not provide specific details on the sample sizes used for each performance test. It mentions "performance testing was conducted," but no numbers of devices tested, number of simulated cases, or specific patient data are given. As this filing is for a mechanical device and discusses performance data but does not explicitly mention clinical studies using patient data, it is highly likely that the testing involved lab-based, benchtop, or simulated use testing of the device's physical and functional characteristics. Therefore, there is no mention of retrospective or prospective data or country of origin for a clinical test set.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

Since the testing described is primarily focused on mechanical and functional performance (e.g., strength, deployment, retention), the concept of "ground truth" established by human experts for diagnostic accuracy studies (like radiologists) is not applicable here. The "ground truth" for these performance tests would be defined by engineering specifications, material properties, and functional benchmarks derived from predicate devices or established standards.

4. Adjudication Method for the Test Set:

Not applicable, as this is primarily a performance and mechanical testing summary, not a study involving human interpretation or diagnostic accuracy where adjudication would be necessary.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done:

No, an MRMC study was not done. The document describes performance testing of the device itself, not a comparative effectiveness study involving human readers with and without AI assistance (which is typical for AI/CAD devices).

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done:

Not applicable. This is not an AI/CAD device.

7. The Type of Ground Truth Used:

For the performance data, the "ground truth" would be established by:

  • Engineering Specifications: Pre-defined design limits and tolerances for force, dimensions, durability, etc.
  • Material Standards: Compliance with known material properties.
  • Predicate Device Performance: Benchmarking against the known performance characteristics of the legally marketed predicate devices.
  • Established Test Methods: Adherence to validated laboratory testing protocols.

8. The Sample Size for the Training Set:

Not applicable. This is not a machine learning or AI device that requires a training set.

9. How the Ground Truth for the Training Set was Established:

Not applicable. This is not a machine learning or AI device.

Dear Karthik Pillai:

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 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

§ 876.4400 Hemorrhoidal ligator.

(a)
Identification. A hemorrhoidal ligator is a device used to cut off the blood flow to hemorrhoidal tissue by means of a ligature or band placed around the hemorrhoid.(b)
Classification. Class II (special controls). Except for a hemostatic metal clip intended for use in the gastrointestinal tract, the device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
