No
The provided text describes a physical vascular graft and its components, with no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is a vascular graft prosthesis used to provide arterial venous access for hemodialysis patients, which is a therapeutic intervention for end-stage renal disease.
No
The HeRO Graft is described as a "non-autogenous (i.e., synthetic) vascular graft prosthesis" intended to provide "arterial venous access." Its purpose is to facilitate hemodialysis for patients who have exhausted other access options, not to diagnose a medical condition.
No
The device description clearly outlines physical components made of materials like silicone, nitinol, ePTFE, and titanium alloy, and describes it as a surgical implant. This indicates it is a hardware medical device, not software-only.
Based on the provided information, the HeRO Graft is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- HeRO Graft Function: The HeRO Graft is a surgical implant designed to provide vascular access for hemodialysis. It is a physical device implanted into the patient's body to facilitate the dialysis process.
- Intended Use: The intended use clearly describes a surgical intervention and a long-term implant for patients with end-stage renal disease. It does not involve the analysis of specimens outside the body.
- Device Description: The description details the physical components of the graft and its implantation process, not a system for analyzing biological samples.
Therefore, the HeRO Graft falls under the category of a medical device (specifically, a vascular graft prosthesis), but not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The HeRO Graft is indicated for end stage renal disease patients on hemodialysis who have exhausted all other access options. These catheter-dependent patients are readily identified using the KDOQI guidelines as patients who:
• Have become catheter-dependent or who are approaching catheter-dependency (i.e., have exhausted all other access options, such as arteriovenous fistulas and grafts).
• Are not candidates for upper extremity fistulas or grafts due to poor venous outflow as determined by a history of previous access failures or venography.
• Are failing fistulas or grafts due to poor venous outflow as
determined by access failure or venography (e.g. fistula/graft salvage).
• Have poor remaining venous access sites for creation of a fistula or graft as determined by ultrasound or venography.
• Have a compromised central venous system or central venous stenosis (CVS) as determined by a history of previous access failures, symptomatic CVS (i.e., via arm, neck, or face swelling) or venography.
• Are receiving inadequate dialysis clearance (i.e., low Kt/V) via catheters. KDOQI guidelines recommend a minimum Kt/V of 1.4.

Device Description
The HeRO Graft is a non-autogenous (i.e., synthetic) vascular graft prosthesis which provides arterial venous access with continuous outflow into the central venous system. The HeRO Graft is composed of the following components: (1) Venous Outflow Component (VOC) with delivery stylet, (2) Arterial Graft Component (AGC) or HeRO Adapter with Support Seal (used in conjunction with commercial vascular grafts), and (3) Accessory Component Kit (ACK). The VOC consists of a radiopaque silicone base tube, a nitinol braid (imparts kink and crush resistance), a distal radiopaque marker band, and an outer silicone elastomer encapsulation layer. During surgery, the VOC is cut to length for the patient anatomy and then advanced over the barbs of the AGC Connector or HeRO Adapter. The AGC is a conventional ePTFE vascular graft with a guideline and beading near the custom titanium alloy connector to provide kink resistance. As an alternative to the AGC, the titanium alloy HeRO Adapter with Support Seal allow the clinician to choose one of the commercially available 6mm ID vascular grafts qualified for use with the HeRO Graft. The HeRO Graft Accessory Component Kit is intended to aid in the implantation of the HeRO Graft and contains instruments including, introducers, dilators, hemostasis valve with stopcock, disposable clamp, and hemostasis plug.
The HeRO Graft is a fully subcutaneous surgical implant single-use device provided sterile via ethylene oxide for long-term (>30 day) use.

(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)

Description | The HeRO Graft is a non-autogenous (i.e., synthetic) vascular graft
prosthesis which provides arterial venous access with continuous
outflow into the central venous system. The HeRO Graft is composed
of the following components: (1) Venous Outflow Component (VOC)
with delivery stylet, (2) Arterial Graft Component (AGC) or HeRO
Adapter with Support Seal (used in conjunction with commercial
vascular grafts), and (3) Accessory Component Kit (ACK). The VOC
consists of a radiopaque silicone base tube, a nitinol braid (imparts kink
and crush resistance), a distal radiopaque marker band, and an outer
silicone elastomer encapsulation layer. During surgery, the VOC is cut
to length for the patient anatomy and then advanced over the barbs of
the AGC Connector or HeRO Adapter. The AGC is a conventional
ePTFE vascular graft with a guideline and beading near the custom
titanium alloy connector to provide kink resistance. As an alternative to
the AGC, the titanium alloy HeRO Adapter with Support Seal allow the
clinician to choose one of the commercially available 6mm ID vascular

Accessory Component Kit is intended to aid in the implantation of the
HeRO Graft and contains instruments including, introducers, dilators,
hemostasis valve with stopcock, disposable clamp, and hemostasis
plug.
The HeRO Graft is a fully subcutaneous surgical implant single-use
