Intended Use

STASIS Gel is intended for sulcus retraction prior to impression making and to control bleeding and gingival oozing in restorative and operative dentistry used with gingival retraction cord. STASIS Gel facilitates the insertion of the cord into the sulcus.

Device Description

Stasis Gel is a 15.5% Ferric Sulfate in a water-based, viscous gel that facilitates sulcus retraction. When applied to the sulcus, the product provides physical displacement of the gingival tissue from the tooth, which in turn, provides a physical barrier to prevent gingival bleeding and oozing from following procedures. Stasis Gel is supplied in a 30 ml or 1.2 ml plastic syringe. The 30 ml syringe is used for bulk storage and 1.2 ml plastic syringe is used for delivery the gel to the sulcus.

AI/ML Overview

This document is a 510(k) summary for the STASIS Gel, a dental device intended for sulcus retraction and control of bleeding/gingival oozing. It primarily focuses on demonstrating substantial equivalence to a predicate device (Vista FS) rather than presenting a detailed study with acceptance criteria for a new AI/software device. Therefore, much of the requested information regarding AI device testing (e.g., sample size for test set, expert qualifications, MRMC study, standalone performance) is not applicable or provided in this document.

However, based on the provided text, I can extract information related to the device's characteristics and the non-clinical testing performed to support its substantial equivalence.

Here's the information that can be extracted, and where the requested information is not applicable, it is noted.

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

Since this is a submission for a medical device (STASIS Gel) and not an AI/software device, the acceptance criteria are based on demonstrating similarity to a predicate device in terms of chemical characteristics, indications for use, and safety. The document does not explicitly state "acceptance criteria" in a quantitative performance metric sense for a software algorithm, but rather compares key attributes.

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

Not applicable. This document describes the non-clinical testing of a physical medical device (STASIS Gel), not an AI/software device. There is no "test set" in the context of clinical images or patient data for AI performance evaluation. The "testing" refers to bench testing and biocompatibility studies.

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. This is for a physical medical device, not an AI/software device requiring expert ground truth for image interpretation or diagnosis.

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

Not applicable. There is no test set or human adjudication process as this is not an AI/software device.

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 is for a physical medical device, not an AI/software device, so an MRMC study is not relevant.

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

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

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

For the physical characteristics and safety:

  • Biocompatibility: In-vitro and in-vivo testing according to ISO 10993-1 standards, which serve as objective ground truth for safety assessments.
  • Chemical Characteristics (Ferric Sulfate content, pH): Laboratory analytical methods that provide objective measurements.
  • Viscosity: Laboratory rheometry methods that provide objective measurements.
  • Shelf-Life: Accelerated aging studies and ongoing real-time aging studies, which provide objective data on product stability over time.

8. The sample size for the training set

Not applicable. This is not an AI/software device that uses "training sets."

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

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

Dear Mohammed Islam:

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/cfpmp/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 devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see
