Intended Use

CalgaeSeal is used to promote the rapid control of bleeding and provide hemostasis for lacerations, abrasions, vascular access sites and following surgical incisions. It can be used to achieve hemostasis at the skin surface for arterial/venous catheterization/tubes, needle puncture, hemodialysis and in patients on anticoagulation therapy. May be used in conjunction with a facility approved, post-hemostasis site dressing.

Device Description

CalgaeSeal is calcium alginate packaged in a Tyvek and Mylar pouch and sterilized by gamma radiation to a 10°-6 SAL and used as a topical hemostasis pad.

CalgaeSeal can be used alone as a wound dressing. It may be used in conjunction with manual pressure or FDA cleared mechanical pressure devices to provide rapid control of bleeding and hemostasis at the skin surface.

AI/ML Overview

This document is a 510(k) premarket notification for the CalgaeSeal device and primarily focuses on establishing substantial equivalence to predicate devices rather than presenting a performance study with acceptance criteria in the manner of a typical AI/ML device submission. Therefore, much of the requested information about acceptance criteria, study design, and ground truth for an AI/ML device is not present in this document.

However, based on the provided text, I can extract the following relevant information:

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

Since this is a 510(k) for a topical hemostasis pad and not an AI/ML device, the "acceptance criteria" here refer to the successful completion of standard biological safety tests for medical devices. The performance is reported as "Pass" and "Identical" to the predicate devices.

Acceptance Criteria (Test)Reported Device Performance (CalgaeSeal)
Biomaterials - skin irritation (ASTM F719)Pass / Identical
Contact Allergens (ASTM F720)Pass / Identical
Intracutaneous Injecting Extracts (ASTM F749)Pass / Identical
Systemic Injections of Extracts (ASTM F750)Pass / Identical

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 in the document. The document refers to "Testing by DeRoyal in 510(k) K914779," suggesting that the current submission relies on the testing performed for a predicate device. Details on the sample size or data provenance for those tests are not in this text.

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 applicable to this type of device and submission. The "ground truth" for these tests would be the established safety standards and the results of laboratory tests, not expert consensus on interpretations.

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

This information is not applicable. Adjudication methods are typically relevant for studies involving human interpretation or assessments, which is not the case for these biological safety tests.

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:

This information is not applicable as this is not an AI/ML device.

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

This information is not applicable as this is not an AI/ML device.

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

The "ground truth" for the tests mentioned (ASTM F719, F720, F749, F750) would be the specific quantitative and qualitative criteria defined within those ASTM standards for passing or failing the biological safety assessments. These are laboratory-based standards for biomaterial safety.

8. The sample size for the training set:

This information is not applicable as this is not an AI/ML device.

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

This information is not applicable as this is not an AI/ML device.

Re: K101097 Trade/Device Name: CalgaeSeal Regulatory Class: Unclassified Product Code: QSY

Dear Byron Zahler:

The Food and Drug Administration (FDA) is sending this letter to notify you of an administrative change related to your previous substantial equivalence (SE) determination letter dated September 22, 2010. Specifically, FDA is updating this SE Letter because FDA has better categorized your device technology under product code QSY.

Please note that the 510(k) submission was not re-reviewed. For questions regarding this letter please contact Julie Morabito, OHT4: Office of Surgical and Infection Control Devices, 240-402-3839, Julie.Morabito@fda.hhs.gov.

Sincerely,

Julie A. Morabito -S

Dear Mr. Zahler:

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. 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 (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set
