Intended Use

The Venaflo Graft with Carbon is indicated for use as a subcutaneous arteriovenous conduit for blood access only.

Device Story

The Venaflo Graft with Carbon is an expanded polytetrafluoroethylene (ePTFE) vascular graft featuring a cuffed venous end and a carbon-lined lumenal surface. It is designed for use as a subcutaneous arteriovenous conduit to provide blood access. The device combines the structural design of the Venaflo ePTFE vascular graft with the carbon-lining technology of the IMPRA Carboflo vascular graft. It is intended for surgical implantation by a physician.

Clinical Evidence

Bench testing only. Testing was performed on the cuffed portion of the device in accordance with ANSI/AAMI VP20-1994 and 1993 FDA Draft Guidance for Vascular Graft Prostheses. Results demonstrated that the device is suitable for its intended use as a subcutaneous arteriovenous conduit and performs substantially equivalent to the predicate devices.

Technological Characteristics

Expanded polytetrafluoroethylene (ePTFE) vascular graft with carbon-lined lumenal surface and cuffed venous end. Dimensions and cuff shape are consistent with the Venaflo ePTFE graft. Testing performed per ANSI/AAMI VP20-1994.

Indications for Use

Indicated for patients requiring a subcutaneous arteriovenous conduit for blood access.

Regulatory Classification

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.

Special Controls

*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.”

Venaflo Vascular Graft Venaflo ePTFE Vascular Graft IMPRA Carboflo® Vascular Graft

#### D. Device Description

The Venaflo Graft with Carbon is an expanded polytetrafluoroethylene (ePTFE) vascular graft with a cuffed venous end and a carbon-lined lumenal surface.

#### Intended Use E.

The Venaflo Graft with Carbon is indicated for use as a subcutaneous arteriovenous conduit for blood access only.

#### F. Technological Characteristics Summary

The Venaflo Graft with Carbon is an IMPRA Carboflo Vascular Graft with a cuffed venous end having the same shape and dimensions as the cuff on the Venaflo ePTFE Vascular Graft.

#### G. Performance Data

Device testing was performed on the cuffed portion of the Venaflo Graft with Carbon and compared to the results of testing performed on the Venaflo ePTFE Vascular Graft. The testing was conducted using methods recommended in ANSI/AAMI VP20-1994: Cardiovascular Implants - Vascular Prostheses and the 1993 FDA Draft Guidance: Guidance for the Preparation of Research and Marketing Applications for Vascular Graff Prostheses. The results of all testing indicated that the Venaflo Graft with Carbon is suitable for use as a subcutaneous arteriovenous conduit for blood access and the anticipated conditions of use imposed on the device. The results demonstrated that the Venaflo Graft with Carbon has been adequately designed to perform in a manner substantially equivalent to that of the predicate devices.

Venaflo Grafts with Carbon are substantially equivalent to the currently marketed Venaflo ePTFE Vascular Graft and the IMPRA Carboflo Vascular Graft.
