Stent Graft Treats Larger Thoracic Aortic Aneurysms


June 8, 2010

A 45 mm diameter stent graft to treat thoracic aortic aneurysms (TAA) is now available in sizes up to 42 mm. W. L. Gore & Associates said the larger version of the Gore Tag Thoracic Endoprosthesis allows treatment of TAAs with proximal and distal neck diameters ranging from 37 to 42 mm.

The Gore Tag is available in 10, 15 and 20 cm lengths. In addition, the devices are delivered on a modified device delivery catheter that is designed for enhanced trackability and deliverability. The modified device delivery catheter uses simple, single-step deployment. The sheathless delivery catheter provides flexibility for navigating tortuous anatomy and low deployment forces.

The device internally relines the thoracic aorta and isolates the diseased segment from blood circulation. The device is comprised of an ePTFE (Gore-Tex) graft with a self-expanding nitinol support structure to combine both device flexibility and material durability. The device is inserted via a catheter delivery technique through a small incision in the patient’s groin.

New newst version of the device was cleared in the United States in June 2010.
