• Attributes: Therapeutic

Intended Use

InterGard Woven collagen coated vascular prostheses are indicated for surgical repair, bypass, or replacement of arteries in the treatment of aneurysmal and occlusive disease of the thoracic and abdominal aorta, visceral arteries, and proximal peripheral arteries. Due to the low porosity of the grafts, these products are recommended for use in patients requiring heparinization prior to or during surgery.

Device Story

InterGard Woven collagen coated vascular prostheses are synthetic grafts used by vascular surgeons for arterial repair, bypass, or replacement. The device functions as a conduit to restore blood flow in patients with aneurysmal or occlusive arterial disease. The graft is coated with collagen to reduce porosity, necessitating patient heparinization during surgical implantation. The device is intended for use in an operating room setting by qualified surgeons. It serves as a permanent implant to replace or bypass diseased arterial segments, thereby restoring hemodynamic function and preventing complications associated with aneurysms or arterial occlusions.

Clinical Evidence

No clinical data provided; substantial equivalence determination based on regulatory review of the 510(k) submission.

Technological Characteristics

Woven vascular prosthesis; collagen-coated surface; low-porosity design. Intended for permanent implantation in the arterial system.

Indications for Use

Indicated for patients requiring surgical repair, bypass, or replacement of arteries due to aneurysmal or occlusive disease of the thoracic aorta, abdominal aorta, visceral arteries, or proximal peripheral arteries. Recommended for patients requiring heparinization due to low graft porosity.

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.”
