No
The device description and performance studies indicate a purely mechanical surgical stapler with no mention of AI or ML capabilities.
No
The device is a surgical stapler used for creating anastomoses by resecting tissue and applying staples. Its function is to join tissues during surgery rather than to treat or cure a disease or condition.
No
Explanation: The device is a surgical stapler used for creating anastomoses in the alimentary tract, not for diagnosing conditions.
No
The device description clearly describes a physical surgical stapler with mechanical components (handle, shaft, staples, anvil, trocar accessory) and a manual activation mechanism. It is a hardware device used in surgical procedures.
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 anastomoses (surgical connections) within the alimentary tract during open and laparoscopic surgeries. This is a surgical procedure performed directly on a patient's body.
- Device Description: The device is a surgical stapler that physically places staples and resects tissue. This is a mechanical surgical tool.
- Lack of Diagnostic Function: There is no mention of the device being used to test samples (like blood, urine, or tissue) outside of the body to diagnose a condition, monitor a patient's health, or screen for diseases.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnostic purposes. This device is a surgical instrument used for treatment, not diagnosis.

Device Description
The EEA™ circular stapler with Tri-Staple™ technology places a circular, triple staggered row of titanium staples and resects the excess tissue, creating a circular anastomosis as an end-to-end, end-to-side or side-to-side anastomosis in both open and laparoscopic surgeries. The instrument is activated by squeezing the handle firmly as far as it will go.
The subject circular stapler will be offered with a medium/thick tissue range which is identified by the purple staple quide and an extra thick tissue range which is identified by the black staple guide. Staplers for medium/thick tissue deploy three height-progressive rows of 3.0 mm, 3.5 mm and 4.0 mm titanium staples. Staplers for extra thick tissue, deploy three height-progressive rows of 4.0 mm. 4.5 mm and 5.0 mm titanium staples. The subject circular staplers are available in 25mm lumen size and 2 shaft lengths; a standard 22 cm shaft and an extra (XL) 35 cm shaft. The Tilt-Top™ anvil is available on all staplers. A blunt and a sharp tipped anvil trocar accessory is provided to assist in introducing the anvil into the surgical field.
Both the subject device and the predicate device (K192330 and K172361) are from the same product family Tri-Staple™ EEA™ stapler. The subject device EEA™ Circular Stapler with Tri-Staple™ Technology (lumen size 25mm) provides the surgeons a choice of additional lumen size selections to best suit the target anatomy.
The subject EEA™ Circular Stapler with Tri-Staple™ Technology is manufactured with the same patient contact materials that are utilized within the predicate device (K192330 and 172361).
In the same manner as the predicate device (K192330 and K172361), the subject EEA™ Circular Stapler with Tri-Staple™ Technology is a manual surgical stapling device that places a circular, triple staggered row of titanium staples and resects tissue, creating a circular anastomosis. The instrument is activated by squeezing the handle firmly as far as it will go. An audible and tactile firing indicator will provide additional feedback of firing completion.
The subject EEA™ Circular Stapler with Tri-Staple™ Technology is a single-use device that is packaged and sterilized via ETO (Ethylene Oxide) with a 5-year shelf life, which is the same as the predicate device (K192330 and 172361).

Device Description:
The EEA™ circular stapler with Tri-Staple™ technology places a circular, triple staggered row of titanium staples and resects the excess tissue, creating a circular anastomosis as an end-to-end, end-to-side or side-to-side anastomosis in both open and laparoscopic surgeries. The instrument is activated by squeezing the handle firmly as far as it will go.
The subject circular stapler will be offered with a medium/thick tissue range which is identified by the purple staple quide and an extra thick tissue range which is identified by the black staple guide. Staplers for medium/thick tissue deploy three height-progressive rows of 3.0 mm, 3.5 mm and 4.0 mm titanium staples. Staplers for extra thick tissue, deploy three height-progressive rows of 4.0 mm. 4.5 mm and 5.0 mm titanium staples. The subject circular staplers are available in 25mm lumen size and 2 shaft lengths; a standard 22 cm shaft and an extra (XL) 35 cm shaft. The Tilt-Top™ anvil is available on all staplers. A blunt and a sharp tipped anvil trocar accessory is provided to assist in introducing the anvil into the surgical field.
Both the subject device and the predicate device (K192330 and K172361) are from the same product family Tri-Staple™ EEA™ stapler. The subject device EEA™ Circular Stapler with Tri-Staple™ Technology (lumen size 25mm) provides the surgeons a choice of additional lumen size selections to best suit the target anatomy.
The subject EEA™ Circular Stapler with Tri-Staple™ Technology is manufactured with the same patient contact materials that are utilized within the predicate device (K192330 and 172361).
In the same manner as the predicate device (K192330 and K172361), the subject EEA™ Circular Stapler with Tri-Staple™ Technology is a manual surgical stapling device that places a circular, triple staggered row of titanium staples and resects tissue, creating a circular anastomosis. The instrument is activated by squeezing the handle firmly as far as it will go. An audible and tactile firing indicator will provide additional feedback of firing completion.
The subject EEA™ Circular Stapler with Tri-Staple™ Technology is a single-use device that is packaged and sterilized via ETO (Ethylene Oxide) with a 5-year shelf life, which is the same as the predicate device (K192330 and 172361).
Indications for Use:
The EEA™ Circular Stapler with Tri-Staple™ Technology has application throughout the alimentary tract for the creation of end-to-end, end-to-side anastomoses in both open and laparoscopic surgeries.
Technological and Performance Characteristics:
The subject device EEA™ circular stapler with Tri-Staple™ technology (lumen size 25mm) is substantially equivalent to the predicate device K192330/K172361 (lumen size 28mm, 31mm and 33mm) regarding the fundamental stapling technologies employed, intended use and indications for use. All EEA™ circular staplers with Tri-Staple™ technology are single-use manual circular staplers that have application throughout the alimentary tract for the creation of end-to-end, endto-side and side-to-side anastomoses in both open and laparoscopic surgeries.
5
The Tri-Staple™ technology used in the subject device is fundamentally the same as the predicate device K192330/K172361. The subject circular staplers are available in 25mm lumen size, meanwhile, the predicates are available in 3 lumen sizes 28mm. 31mm and 33mm. That's why a reference device K062850 offering 25mm lumen size is to be introduced as control device in performance testing.
Substantial Equivalent:
The subject new product models have the same intended use and indications for use as the predicate device.
They are same in fundamental scientific technology in that they are all sterile, single used, handheld, manual surgical instruments equipped with titanium staples intended to be used during open or laparoscopic surgical procedures of the alimentary tract, to create anastomoses (end-to-end, end-to-side, or side-to-side) via intraluminal (within the lumen) resection. The subject and predicate devices are same in design, materials and are sterilized via ethylene oxide, but different in lumen size.
The below table further summarizes the similarities and differences between the subject and predicate devices.
