Intended Use

The Sarns® Centrifugal Pump with or without X-Coating™ is a sterile, single use device, used as an extracorporeal blood pump for use in cardiopulmonary bypass procedures for up to 6 hours. The pump is intended for use with the Sarns® Centrifugal Systems or may be used with Stöckert Centrifugal Pump Systems by attaching the Sarns® Centrifugal Pump Adapter.

Device Description

The Sarns® Centrifugal Pump (with or without X-Coating™) is a single use, sterile and disposable device. It is used to pump blood through the extracorporeal circuit during cardiopulmonary bypass surgery and may be used for up to 6 hours. The pump has a priming volume of 48ml. The pump rotational speed is 0-3600 RPM resulting in a flow capacity of 0-9.9 LPM. With this submission, the sterile disposable Sarns® Centrifugal pump may be used with Stöckert Centrifugal pump systems when the reusable Sarns® Centrifugal Pump Adapter is used. The Sarns® Centrifugal Pump Adapter is a device designed with geometries that mate the Stöckert centrifugal systems to the Sarns® Centrifugal pump. The housing is a hard plastic (acetal) that slides easily onto the Sarns® Centrifugal pump then clips into place. The adapted pump is then mounted onto the Stöckert Centrifugal pump systems.

2. Sample size used for the test set and the data provenance:

The document does not explicitly state the sample sizes used for each test. The studies appear to be prospective in nature, as they involve testing the "proposed device" configuration against "predicate device" configurations or established standards. There is no information regarding the country of origin of the data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not applicable. The studies described are engineering and performance validation tests, not clinical evaluations requiring expert interpretation of medical images or data to establish ground truth.

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

This information is not applicable. The studies described are engineering and performance validation tests with objective pass/fail criteria, not clinical evaluations requiring adjudication from multiple experts.

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 a medical device (centrifugal pump) and not an AI-powered diagnostic or assistive technology that would involve human readers.

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

Not applicable. This device is a mechanical pump, not an algorithm.

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

The "ground truth" for these tests is based on pre-defined performance standards, technical specifications, and comparisons to the legally marketed predicate device's established performance. For example:

  • Flow curves: Comparison to predicate device's established flow characteristics.
  • Clip fatigue: Designed lifetime use specification (7 years).
  • Change out time: Statistical similarity to predicate device's change out time.
  • Shipping and durability: Absence of damage and intended function, likely against internal or industry standards.
  • Hemolysis: Absence of statistical difference in blood parameters compared to performance without the adapter.
  • Disconnection force: Greater than or similar to predicate device.
  • Interaction with HLM: No interference with control and safety components.

8. The sample size for the training set:

Not applicable. This device does not use machine learning or AI, so there is no "training set."

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

Not applicable, as there is no training set for this type of device.
