| Ink Adhesion | Satisfy appropriate specifications (implied: maintains legibility) | Passed pre-determined acceptance criteria |
| Hemolysis | Satisfy appropriate specifications (implied: low or acceptable levels of hemolysis; straight tip design generally produces slightly lower pressure drop, thus less potential for hemolysis than predicate's angled tip) | Passed pre-determined acceptance criteria |
| Pressure Drop | Satisfy appropriate specifications (implied: low resistance to flow; straight tip design generally produces slightly lower pressure drop) | Passed pre-determined acceptance criteria |
| Exit Velocity | Satisfy appropriate specifications (implied: comparable to predicate device) | Passed pre-determined acceptance criteria |
| Biocompatibility | Full support of FDA General Program Memorandum #G95-1 / ISO 10993 (implied: no adverse biological reactions) | Passed pre-determined acceptance criteria |
Note on Acceptance Criteria: The document states that "performance studies were conducted to ensure...passed pre-determined acceptance criteria." However, the specific quantitative acceptance criteria for each test are not explicitly detailed in the provided text. They are implied to be "appropriate device performance specifications" and to ensure "no appreciable differences in performance between the subject devices and the predicate devices."
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the sample size used for the test set as it refers to these as "bench studies" and "performance evaluations" rather than a clinical human-subject study. The data provenance is retrospective in the sense that the evaluations were done on already manufactured devices as part of a premarket notification (510(k)) process. The location of the testing is not explicitly stated, but it would have been conducted by Terumo Cardiovascular Systems Corporation or a contracted lab. There is no mention of country of origin for test data in the context of human subjects, as no clinical studies were performed.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This was a medical device regulatory submission for a physical device, and the "ground truth" was established through engineering and laboratory testing against predetermined specifications, not through expert consensus on medical images or clinical outcomes.
4. Adjudication Method for the Test Set
Not applicable. As noted above, this was a medical device regulatory submission for a physical device, not related to expert review of data that would require 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
Not applicable. This device is an aortic cannula for cardiopulmonary bypass surgery. It is a physical medical device and does not involve AI or human "readers" in the context of diagnostic interpretation.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done
Not applicable. This device is an aortic cannula, not a software algorithm.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for the performance evaluations was established by engineering specifications and industry standards for medical devices (e.g., ISO 10993 for biocompatibility). These criteria are designed to ensure the device performs safely and effectively for its intended use, comparable to legally marketed predicate devices.
8. The Sample Size for the Training Set
Not applicable. There is no "training set" in the context of this physical medical device. The "training" for such devices typically involves design iterations and prototyping, which are then subject to the performance evaluations described.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As there is no "training set" in the AI or clinical study sense, this question does not apply. The analogous process for a physical device would be the iterative design and manufacturing process guided by established engineering principles and regulatory requirements.

Comparison of Intended Use: .
The modified Sarns™ Soft-Flow® Extended Aortic Cannula and the predicate have the exact same intended use statements:
The modified and the unmodified devices are each indicated for perfusion of the ascending aorta during cardiopulmonary bypass surgery for up to 6 hours of use.
Duration of Use:
The modified Sarns™ Soft-Flow® Extended Aortic Cannula and the predicate can both be used in procedures lasting up to 6 hours in duration.
Comparison of Labeling:
The labeling used for the modified device is similar to the labeling used with the predicate device, although some labeling is revised to provide greater clarity for the use.

Image /page/2/Picture/0 description: The image shows the logo for Terumo Cardiovascular Systems. The logo consists of a circle with the letter "T" inside, followed by the word "TERUMO" in bold, sans-serif font. Below the word "TERUMO" are the words "Cardiovascular Systems" in a smaller, sans-serif font. The logo is black and white.
The Sarns™ Soft-Flow® Extended Cannula is 14.5 inches long, one-half inch longer than the 14 inch predicate device. This half inch difference in length is not clinically significant. Longer tubing allows clearance from and, thus improved visualization of, the surgical field, particularly in larger patients.
The Sarns™ Soft-Flow® Extended Cannula has a positional suture ring and depth . markings on the tubing. The positional suture ring and centimeter depth markings are used to gauge insertion depth of the cannula and provide a location to tighten the sutures around the cannula to hold it in place. These features are comparable in function to the predicate device which has a suture bulb to gauge insertion depth of the cannula and provide a location to tighten the sutures around the cannula to hold it inc place.
The Sarns" Soft-Flow "Extended Cannula has a straight tip rather than an angled tip like the predicate devices. A straight tip design generally produces a slightly lower pressure drop (the difference between the pressure entering the camula and the pressure leaving the cannula) compared to the same size angled tip. A lower pressure drop is desirable because there is less resistance to flow and thus less potential for hemolysis.
The material that is used for the luer-threaded port cap is changed from polypropylene to ABS plastic. Terumo Cardiovascular Systems maintains a complete profile of all biocompatibility data that fully supports the suggested elements of FDA General Program Memorandum #G95-1: Use of International Standard ISO 10993, "Biological Evaluation of Medical Devices Part I: Evaluation and Testing,"
Comparison of Materials : ----------------------------------------------------------------------------------------------------------------------------------------------------
The materials of construction used in the modified Sarns™ Soft-Flow® Extended Aortic Cannula are the same generic materials that are used in the predicate device with the exception of a cap material change from polypropylene to ABS plastic.
Comparison of Performance:
Terunio Cardiovascular has conducted performance studies with the modified devices to ensure that they all continue to satisfy appropriate device performance specifications and to ensure that they satisfy customer needs. Specifically, performance studies were conduced to ensure force at break, liquid and air leak, hemolysis, pressure drop, exit velodity, ink adhesion, and biocompatibility testing passed pre-determined acceptance criteria. There are no appreciable differences in performance between the subject devices and the predicate devices. The nonclinical tests demonstrate the subject device is as safe and effective as the predicate devices.
Conclusion:
The information and data included in the 510(k) notice demonstrate the Sams™ Soft-Flow Extended Aortic Cannula is substantially equivalent to the predicate devices for perfusion of the ascending aorta during cardiopulmonary bypass for up to 6 hours of use.
