No
The device description and performance studies focus on the physical properties and surgical function of a staple line reinforcement material, with no mention of AI or ML capabilities.
Yes
The device is described as an "absorbable staple line reinforcement material" that provides "support to soft tissue during the healing process" and is used as "a buttress to provide support during the healing process," indicating a therapeutic function in aiding tissue repair and healing.
No
Explanation: The device is a surgical buttress for reinforcing staple lines during soft tissue transection or resection procedures, providing support during the healing process. Its function is interventional/therapeutic, not diagnostic.
No
The device description clearly states that the device is a physical, absorbable staple line reinforcement material composed of fibers and films, intended for implantation during surgery. It is a hardware device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for surgical procedures involving soft tissue transection or resection with staple line reinforcement. This is a surgical device used during a procedure on the patient's body.
- Device Description: The description clearly states it's a "staple line reinforcement, also known as a buttress, for use in the surgical environment for the purpose of reinforcing a staple line." It's an implantable material that provides support during the healing process.
- Lack of IVD Characteristics: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. The provided text does not mention any testing of samples or diagnostic purposes.
Therefore, the ECHELON ENDOPATH Staple Line Reinforcement is a surgical implant/device, not an In Vitro Diagnostic.

Device Description
Echelon Endopath Staple Line Reinforcement is a staple line reinforcement, also known as a buttress, for use in the surgical environment for the purpose of reinforcing a staple line.
The Subject Device is to be used Echelon Endopath GST 60 mm reloads in conjunction with the Echelon family of 60 mm endoscopic linear cutters. The Echelon 60 mm Stapler in conjunction with the Echelon Endopath GST60 mm reload places staggered rows of titanium staples with a reinforcement material, and simultaneously divide the tissue and the reinforcement material between the stapled rows. The Subject Device is an absorbable staple line reinforcement material which is secured to the stapler anvil and reload with a synthetic attachment material. The Subject Device contains an applicator and the implantable device which consists of 3 materials: the Vicryl material, the Polydioxanone film and the attachment material. Echelon Endopath Staple Line Reinforcement is an implanted material which works as an adjunct to surgical staples after transection, to provide support to soft tissue during the healing process.
The Echelon Endopath Staple Line Reinforcement Subject Device and Predicate Device are both synthetic, absorbable staple line reinforcement materials to be applied to staplers to provide support to the staple line during the tissue healing process. The Subject Device is to be applied to the Ethicon Echelon Flex Powered Plus Stapler. Both materials degrade via hydrolysis and have been evaluated for biocompatibility in alignment with ISO 10993-1 and are deemed biocompatible.
Echelon Endopath Staple Line Reinforcement is composed of undyed multifilament fibers identical to those used in Vicryl surgical sutures. The polyglactin 910 implant is knitted by a process which interlocks each fiber juncture to prevent unraveling. The implanted material consists of a Vicryl layer laminated with a PDO film on each side, and a Buttress Attachment Material which is a synthetic material applied to the top outer surface of each implant. The staple line reinforcement is used as a buttress to provide support during the healing process. Both Subject and Predicate materials are hydrolyzed by body fluids and absorbed after serving the intended function. The subject Device absorption is essentially complete at 120 days.
The primary difference between the Subject and Predicate Devices is the feature for loading and delivery of the device to the implantation site. A thin layer of bioabsorbable adhesive is coated onto one surface of the implantable device and is composed of a synthetic polymer/poloxamer blend to attach the Subject Device to the stapler. Whereas the Predicate Device utilized a sleeve construction and suture pullcord to secure the reinforcement material on the stapler.

Summary of Similarities and Differences in Technological Characteristics
Staple line reinforcement is the technological principle for both the Subject Endopath Echelon Staple Line Reinforcement and the Predicate Gore® Seamguard® Reinforcement device. It is based on the use of applying an absorbable material, also known as a buttress, as a reinforcement to the transected surgical staple line in soft tissue. At a high level, the Subject and Predicate Devices are based on the following same technological elements:
- Staple line reinforcement device is applied to a surgical stapler
- Staple line reinforcement and stapler are positioned on the desired anatomical area to be transected
- Stapler is fired, knife proceeds to transect tissue, and staples with buttress are applied to ● the tissue
- Absorbable implant reinforces tissue and helps to secure the staple line ●

The Endopath Echelon Staple Line Reinforcement differs from Predicate Gore® Seamguard® Reinforcement device in the Steps for Use to load the buttress device onto the surgical stapler. The Subject Device uses an attachment material to permit temporary attachment to the surgical stapler.
Both devices are sterile, single use, absorbable implants that absorb over time. The Subject Device absorbs over approximately 120 days, the Predicate Device absorbs over approximately 180 days.
