The summary describes a vascular graft and its manufacturing process, with no mention of AI or ML technology.
Yes
The device is a vascular graft for the replacement or repair of arteries, which is a therapeutic intervention for a disease.
No
The device is a vascular graft for replacing or repairing arteries, which is a therapeutic function, not a diagnostic one.
No
The device description clearly indicates a physical vascular graft made of woven material, not software. The performance studies also describe physical testing of the graft's properties.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the "replacement or repair of arteries affected with aneurysmal or occlusive disease." This is a surgical procedure performed directly on the patient's body.
- Device Description: The device is a "Woven Double Velour Vascular Graft," which is an implantable medical device used to replace or repair blood vessels.
- Lack of IVD Characteristics: IVD devices are used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The description of this device and its use does not involve any of these activities.
Therefore, the Hemashield Gold ™ Woven Double Velour Vascular Graft is a surgical implant, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Hemashield Gold ™ Woven Double Velour Vascular Graft is indicated for use in the replacement or repair of arteries affected with aneurysmal or occlusive disease. The prosthesis is also recommended for use in patients requiring systemic heparinization prior to, or during, surgery.

§ 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.”
