The summary describes mechanical surgical staplers and does not mention any AI/ML components or capabilities.
Yes
The device is described as a surgical stapler used for "transection, resection, and/or creation of anastomoses" in the gastrointestinal and alimentary systems, which are therapeutic medical procedures.
No
Explanation: The device is described as a surgical stapler used for cutting tissue and creating anastomoses. Its function is to perform a surgical procedure, not to diagnose a condition.
No
The device description clearly details physical hardware components (staplers, loading units, titanium staples, circular knife) and performance tests related to mechanical properties (firing force, staple formation, tensile strength, etc.), indicating it is a physical medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes the device's application in surgical procedures for transection, resection, and creation of anastomoses within the gastrointestinal and alimentary tracts. This is a direct surgical intervention on the body.
- Device Description: The description details a mechanical device that physically manipulates tissue by placing staples and cutting. This is a surgical instrument.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information for diagnosis, monitoring, or treatment. The device itself is performing a surgical action, not analyzing biological samples.
- Performance Studies: The performance studies focus on the mechanical and biological compatibility of the device itself (firing force, staple formation, biocompatibility, etc.), not on the accuracy or reliability of diagnostic information derived from biological samples.
In summary, the device is a surgical stapler used for physical manipulation of tissue during surgery, which falls under the category of a surgical instrument, not an In Vitro Diagnostic device.

Device Description
The Linear Cutter Staplers and Loading Units for Single Use place two double staggered rows of titanium staples and simultaneously cut and divides tissue between the two double rows. The device is available in 60mm, 80mm and 100mm length with reload in 2.5mm and 4.5mm staple size to accommodate various tissue thicknesses. The device may be reloaded and fired up to 8 times in a single procedure.
The Circular Staplers for Single Use places a double staggered, circular row of titanium staples upon activation, which was achieved by squeezing the handles firmly as far as they could go. Immediately after formation of the staples, the excess tissue will be resect by the circular knife, and then a circular anastomosis is created. The stapler is available in 33mm, 29mm, 25mm and 21mm five specifications. Two staple sizes (3.5mm and 4.8mm) are available to accommodate various tissue thicknesses.

Dear Ms. Hong:
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
9
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 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/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (OS) 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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
