Intended Use

The Portaclamp™ is indicated to clamp the aorta during minimally invasive cardiac surgery implying the usage of an extra-corporeal circulation.

Device Description

The Portaclamp™ is a disposable aortic clamping device that is designed to be used through a standard thoracic port to clamp the aorta during minimally invasive cardiac bypass procedures. The Portaclamp™ consists of a flexible guide wire, two jaws that are passed over the guide wire and positioned on each side of the aorta. and a mandrel that is slid along the length of the jaws to compress the jaws and clamp the aorta.

AI/ML Overview

The provided text describes a medical device, the Portaclamp™, and its substantial equivalence to predicate devices, but it does not contain the specific information requested in the prompt regarding acceptance criteria and a study that quantitatively proves the device meets those criteria.

Here’s a breakdown of what the document does mention and what is missing:

1. Table of acceptance criteria and the reported device performance

  • Missing. The document only states "Information submitted in this premarket notification for the Portaclamp™ includes results of biocompatibility testing, in vitro performance testing, cadaver testing and clinical experience." It does not provide specific acceptance criteria (e.g., "Device must achieve a clamping force of X Newtons") or the corresponding reported performance values.

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

  • Missing. The document mentions "cadaver testing and clinical experience" but provides no details on sample size, study design (retrospective/prospective), or data provenance.

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)

  • Missing. The concept of "ground truth" as typically applied to AI performance evaluations is not present in this 510(k) summary for a physical medical device like a clamp. Clinical evaluations for such devices typically focus on safety and effectiveness outcomes.

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

  • Missing. Not applicable to this type of device submission as it doesn't involve subjective assessment of images or data by multiple experts for adjudication.

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

  • Missing. This is entirely inapplicable as the Portaclamp™ is a physical surgical device, not an AI-assisted diagnostic tool for human readers.

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

  • Missing. This is entirely inapplicable as the Portaclamp™ is a physical surgical device, not an algorithm.

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

  • Missing. As mentioned above, the concept of "ground truth" as related to AI/diagnostic performance is not applicable here. Performance is typically assessed through measures like successful clamping, absence of tissue damage, durability, etc.

8. The sample size for the training set

  • Missing. This is entirely inapplicable as the Portaclamp™ is a physical surgical device, not an AI algorithm that requires a training set.

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

  • Missing. This is entirely inapplicable as the Portaclamp™ is a physical surgical device, not an AI algorithm that requires a training set.

In summary, the provided 510(k) summary for the Portaclamp™ is a regulatory document focused on demonstrating substantial equivalence to existing predicate devices. It mentions various types of testing (biocompatibility, in vitro, cadaver, clinical experience) but does not delve into the detailed quantitative performance metrics, acceptance criteria, sample sizes, or expert adjudication methods that would be relevant for evaluating the performance of an AI/diagnostic device as requested in the prompt.

4. DEVICE DESCRIPTION

The Portaclamp™ is a disposable aortic clamping device that is designed to be used through a standard thoracic port to clamp the aorta during minimally invasive cardiac bypass procedures.

5. INTENDED USE

The Portaclamp™ is indicated to clamp the aorta during minimally invasive cardiac surgery implying the usage of an extra-corporeal circulation.

6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE

The Portaclamp™System is substantially equivalent to other predicate vascular clamps that are used for aortic clamping during cardiac surgery. The Portaclamp™ and the predicate devices have fundamentally the same indications for use. All of these devices are designed to be used to temporarily clamp vessels during surgical procedures. such as the aorta during cardiac surgery.

PERFORMANCE TESTING 7.

Information submitted in this premarket notification for the Portaclamp™ includes results of biocompatibility testing, in vitro performance testing, cadaver testing and clinical experience.

Dear Mr. Veale:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
