The Disposable Powered Articulating Endoscopic Linear Cutter Stapler & Reloads are intended for transection, resection, and/or creation of anastomoses. The instruments have application in multiple open or minimally invasive general abdominal, gynecologic, thoracic, and pediatric surgical procedures.

Device Description

The Disposable Powered Articulating Endoscopic Linear Cutter Stapler & Reloads are sterile. single patient use instruments that simultaneously cut and staple tissue through a battery powered firing system. The Power Stapler and Reloads are sterilized by irradiation. The instruments deliver six staggered rows of staples, three on either side of the cut line. The instruments are available in three shaft lengths: compact (192±20mm), regular (252±20mm) and long (352±20mm). The shaft can rotate freely in both directions and incorporates an articulation mechanism, which enables the distal portion of the shaft to pivot to facilitate lateral access to the operative site.

AI/ML Overview

This document is a 510(k) Pre-market Notification for a medical device, specifically a "Disposable Powered Articulating Endoscopic Linear Cutter Stapler & Reloads." This type of document is filed with the FDA to demonstrate that a new device is substantially equivalent to a legally marketed predicate device, rather than to prove its safety and effectiveness through a comprehensive clinical study per se.

Therefore, the requested information regarding "acceptance criteria" and "study that proves the device meets the acceptance criteria" in the context of AI/Software device performance is not applicable to this document. This document describes a physical surgical stapler and its reloads, not a software or AI medical device.

The "Performance Data" section (Section 9) describes non-clinical performance tests conducted to demonstrate substantial equivalence to a predicate device, not to establish performance criteria for an AI or software algorithm.

Here's why each of your requested points cannot be answered from this document:

A table of acceptance criteria and the reported device performance: The document lists non-clinical tests (e.g., Visual Appearance, Sterility, Hardness, Anastomosis and Cutting Performance) and states, "During verification testing, all data meets pre-defined criteria." It does not provide specific numerical acceptance criteria or reported performance values for these physical device attributes. It also doesn't relate to AI/software performance.
Sample sized used for the test set and the data provenance: Not applicable. The tests are for a physical device, not an algorithm's test set. There's no "data provenance" in the sense of clinical data (e.g., country of origin, retrospective/prospective).
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for an AI/software device is not relevant here.
Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
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 not an AI-assisted device.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable.
The sample size for the training set: Not applicable. There is no training set mentioned as this is not an AI/software device.
How the ground truth for the training set was established: Not applicable.

In summary, this 510(k) submission focuses on demonstrating the substantial equivalence of a physical surgical stapler to an existing one. It does not involve AI or software, and therefore, the questions about acceptance criteria and study design for such devices are not relevant to the information provided in this document.

Dear Julie Chen:

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/cfpmn/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

{1}------------------------------------------------

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 https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

{7}------------------------------------------------

Technological Characteristics [21 CFR 807.92(a)(6)] 8.

The Disposable Powered Articulating Endoscopic Linear Cutter Stapler has not changed in the basic design, mechanism of action, intended use when compared to the predicate device. There is no change to reloads in material and structure. The only difference in the current submitted device is the physical appearance of rotating knob, shells and addition of reloads removers.

9. Performance Data

Non-Clinical Performance Test Conclusion

There is no FDA recognized performance standard for implanted reloads and staplers. Non-clinical tests were conducted to verify that the proposed device met the requirements of design change and was Substantially Equivalent (SE) to the predicate device. The testing was as follows:

Visual Appearance ●
Sterility ●
Package Seal ●
. Hardness
Anastomosis and Cutting Performance ●
Safety Device
Pressure Resistant Properties ●
Sharpness
Surface Roughness
Flexibility ●
o Matching Performance
Firing Electric Current
Battery Voltage
Motor Rotation Speed ●
Dimensions ●

During verification testing, all data meets pre-defined criteria.

Clinical Test Conclusion

No clinical study is included in this submission.

10. Conclusion

The conclusion drawn from the nonclinical tests demonstrates that the subject device, Disposable Powered Articulating Endoscopic Linear Cutter & Reloads is substantially equivalent to the predicate device.
