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

  • Woven double velour impregnated polyester graft
  • Porosity < 5 mL/min/cm2

Superior Construction and Material

  • Advanced construction and double-pass sewing technique provides an
    improved anastomotic seal.
  • Proprietary collagen impregnation reduces porosity to improve hemostasis.
  • Soft, flexible woven material conforms to host vessel for easier anastomosis.
  • Provides superb tissue ingrowth and long-term patency.

Excellent Healing

  • Excellent long-term biocompatibility and durability
  • Promotes formation of a smooth, thin pseudointima
  • Provides controlled resorption for uniform tissue ingrowth

Exceptional Handling

  • Soft, flexible woven material designed to conform to host vessel for easy
  • Smooth needle passage and excellent suture retention helps reduce bleeding at
    the anastomosis
  • Highly compliant material promotes a snug fit at the anastomosis

Optimal Hemostasis

  • Proprietary collagen-impregnation process promotes optimal healing response
  • No pre-clotting required, minimizing suture-hole bleeding
