Intended Use
The Disposable Circular Stapler has application throughout the alimentary tract for end-to-end, end-to-side and side-to-side anastomoses.
Device Description
The disposable circular stapler is preloaded with two staggered rows of titanium staples in both inner and outer circles. After the deploying of the instrument, the circular knife blade inside the instrument can cut off excess tissue automatically to create a circular anastomosis. The instrument is fired by squeezing the trigger handle firmly as far as it will go. The size of the anastomosis site is determined by the diameter of the selected circular knife blade.
More Information

Not Found

No
The description focuses on mechanical function and does not mention any AI/ML components or capabilities.

No
This device, a disposable circular stapler, is used for mechanically joining tissues (e.g., in anastomosis) rather than treating a disease or condition. Its primary function is a surgical tool, not a therapeutic intervention itself.

No
The device, a disposable circular stapler, is described as having an application for creating end-to-end, end-to-side, and side-to-side anastomoses by deploying staples and cutting excess tissue. This is a surgical function, not a diagnostic one.

No

The device description clearly describes a physical, mechanical surgical stapler with titanium staples and a knife blade, which is a hardware device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for creating surgical anastomoses within the alimentary tract. This is a surgical procedure performed directly on a patient's body.
  • Device Description: The device is a surgical stapler used to cut and staple tissue during surgery.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue samples) outside of the body to provide information about a patient's health status.

IVD devices are used to perform tests on samples taken from the human body to diagnose diseases, monitor conditions, or screen for health issues. This device is a surgical tool used for treatment, not diagnosis.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

In order to establish substantial equivalence to the identified predicate device's) we performed the following tests: for biocompatibility we performed cytotoxicity, sensitization, irritation and acute systemic toxicity testing and the results of the testing provided evidence that the device was biocompatible. For assessment of device performance characteristics we assured that the device met all performance standards for implanted titanium and for package integrity and shelf life assessments following sterilization we assessed the results of the Tensile Seal Strength Test, Package Verification Test, Vacuum Leak Test, Impermeability Fusion Test, Agar Contact-Attack Test and Accelerated Aging Testing. The results of all of these tests provided evidence that the subject device was substantially equivalent to the predicate device.

Dear Mr. Mack:

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. 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.
