Gore announced on 19 January 2011 the European availability of the Gore Viabahn endoprosthesis on a lower profile delivery system. The announcement came during the Leipzig Interventional Course in Germany. The new Gore Viabahn lower profile delivery system received CE mark approval in late 2010.
The Gore Viabahn device is designed to percutaneously treat peripheral artery disease by relining the native vessel. This next generation stent graft enables a reduction in delivery profile to 6F for 5 and 6mm devices and 7F for 7 and 8mm devices and is delivered over a 0.018” or 0.014” guidewire. The reduced delivery profile will provide interventionalists with greater options for delivery with the same trackability and device performance in treating stenosis and occlusions of the superficial femoral artery and other peripheral arteries where a small access size is critical.
The Viabahn endoprosthesis is the only device of its kind in Europe, approved for endovascular grafting of peripheral arteries. The new Gore Viabahn device delivery catheter is available in a 120cm length and incorporates the propaten bioactive surface, which utilises endpoint immobilisation of derivatised heparin to the endoprosthesis luminal surface. This proprietary surface technology preserves the heparin bioactive sites such that they remain free to interact with the blood at the device surface without being consumed.
“A reduction in profile seen in the Gore Viabahn endoprosthesis means easier endovascular delivery of the device to treat occlusions in the superficial femoral artery and other tough to reach locations in patients where a small access size is critical and includes all of the historical benefits of heparin-bonded propaten bioactive surface,” said Daniele Savio, Vascular and Interventional Radiology, San Giovanni Bosco Hospital, Torino, Italy.
