HEMASHIELD PLATINUM Woven Double Velour Vascular Grafts
The most used, most studied vascular products available in the market.
HEMASHIELD PLATINUM Woven Double Velour Grafts are collagen-impregnated and come in straight, one-branch, or multi-branch graft configurations for aortic repair.
Trusted for more than 20 years, HEMASHIELD grafts are the most used, most studied vascular products available in the market today. More than 2 million HEMASHIELD grafts have been implanted worldwide, demonstrating clinical
efficacy and improved outcomes. These grafts have superior healing, improved tissue ingrowth, higher patency, excellent biocompatibility, and proven efficacy.
HEMASHIELD PLATINUM Branch Grafts: A Graft Designed for Each Technique
In addition to straight and bifurcated options, the following products with presewn branches offer versatility and convenience for a wide variety of aortic repair techniques and procedures.
Four-Branch Graft: Observed clinical advantages of the four-branch arch graft replacement include
- Dramatically reduced cerebral circulatory arrest times1,2,3
- Significantly lowered risk of mortality and risk of neurologic dysfunction2
- Negated the need for direct cannulation of brachiocephalic arteries, which reduces the risk of embolization of air or atherosclerotic debris1,2
- Provides an alternative technique to the Island Technique with retrograde
perfusion via femorals
Angled Four-Branch Graft
- This four-branch graft Includes one branch for perfusion and three angled branches (60 degrees) for repair or replacement of the head vessels
- Angled design mimics the natural anatomy of the head vessels
One-Branch Graft: The straight and one-branch grafts may be used for various procedures, including
- Ascending thoracic aortic repair
- Descending thoracic aortic repair
- Ascending and innominate repair (with one-branch graft)
- Island Technique for arch repair
Thoraco-Abdominal Aortic Aneurysm (TAAA) Graft
- Designed for repair or replacement of the thoracic and abdominal portions of the aorta
- Applications include replacement of the right and left renal arteries as well as the superior mesenteric artery and celiac arteries

Potential Adverse Effects
Bleeding; thrombosis; embolism; graft infection; aneurysm; psuedoaneurysm. Please be aware that potential adverse effects may arise even with the proper use of medical devices. Accordingly, this device should only be used by persons qualified in the procedures for which it is indicated.
Woven grafts should be cut with a low temperature, disposable cautery (e.g., approximately 900 degrees F/approximately 500 degrees C) to prevent raveling. Safety and effectiveness of this product in the extra-anatomic, A-V access, and pulmonary positions, and as a patch have not been established.
