Advanta VXT and Flixene vascular grafts are indicated for use in patients with peripheral vascular disease, where peripheral arteries must be repaired or replaced and open surgery is required. Indications for use also includes patients with end stage renal disease requiring arteriovenous vascular access for dialysis.

Device Description

Atrium ePTFE vascular grafts are offered in a variety of designs; (including Advanta VXT and Flixene). They are made primarily of expanded polytetrafluoroethylene (ePTFE), and are available in a wide variety of configurations:

. "Rings" (also referred to as "helix") for added radial support (made from a PTFE monofilament coil)
. The Slider Graft Deployment System consisting of a pre-attached tip(s) with a clear flexible sheath (polyethylene)
. Tapered end
. Thin or standard wall thickness

The Advanta VXT graft is a 2-layer graft employing a single-layer ePTFE graft, which is then wrapped with an additional layer of ePTFE for increased support. The rings available on some Advanta VXT grafts are bonded to the exterior surface of the graft. By following the prescribed procedure, the rings can be removed incrementally as needed. The Flixene vascular graft is a 3layer graft comprised of ePTFE. This graft was designed with an additional layer of ePTFE. As a result of its design, ring support is not necessary. Implantable portion of graft is comprised of polytetrafluoroethylene (PTFE) with no more than 0.1% cobalt chromite blue-green Spinel ink on surface of the graft, which is used as a reference line. Additional materials in transient contact during placement of the graft include 303 stainless steel and polyethylene, which represents the graft deployment system and transfer sleeve.

AI/ML Overview

The provided text is a 510(k) premarket notification for a medical device (vascular grafts) and does not contain information related to an A.I./algorithm-driven device or study. Therefore, I cannot extract the requested information regarding acceptance criteria and study data for an A.I. device from this text.

The document focuses on demonstrating substantial equivalence of the Advanta VXT and Flixene Vascular Grafts to previously cleared predicate devices, primarily through non-clinical bench testing. It explicitly states: "There were no clinical studies of the modified device." and "The Advanta VXT and Flixene Vascular Grafts are substantially equivalent to the predicate devices in the fundamental scientific technology of the device. The design verification and validation testing established that the Advanta VXT and Flixene Vascular Grafts are substantially equivalent to the predicate devices."

As such, I cannot provide:

A table of acceptance criteria and reported device performance for an AI/algorithm.
Sample sizes for a test set or data provenance for an AI/algorithm.
Number of experts or their qualifications for establishing ground truth for an AI/algorithm.
Adjudication methods for an AI/algorithm test set.
MRMC comparative effectiveness study results for AI assistance.
Standalone performance of an algorithm.
Type of ground truth for an AI/algorithm.
Sample size for a training set for an AI/algorithm.
How ground truth for a training set was established for an AI/algorithm.

Dear Hannah Scribner:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review. the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

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

Regulation Number and Section

§ 870.3450 Vascular graft prosthesis.

(a)
Identification. A vascular graft prosthesis is an implanted device intended to repair, replace, or bypass sections of native or artificial vessels, excluding coronary or cerebral vasculature, and to provide vascular access. It is commonly constructed of materials such as polyethylene terephthalate and polytetrafluoroethylene, and it may be coated with a biological coating, such as albumin or collagen, or a synthetic coating, such as silicone. The graft structure itself is not made of materials of animal origin, including human umbilical cords.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Guidance Document for Vascular Prostheses 510(k) Submissions.”
