W. L. Gore & Associates tells us its GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis (VBX Stent Graft) has received U.S. FDA approval for treatment of de novo or restenotic lesions found in iliac arteries, including lesions at the aortic bifurcation.

Gore says its portfolio of peripheral vascular solutions is designed and tested so physicians can more reliably treat patients with a wide range of challenging peripheral disease presentations and improve those patients’ outcomes. Each interventional solution is engineered for durability, accuracy, thromboresistance and conformability, and is backed by dedicated service to help improve patient outcomes.

The VBX Stent Graft was developed utilizing the small diameter, ePTFE stent graft technology from the GORE® VIABAHN® Endoprosthesis. The VBX Stent Graft is available in a range of diameters from 5 to 11 millimeters and lengths of 15, 19, 29, 39, 59, and 79 millimeters to cover a wide variety of treatment needs.

In the Gore VBX FLEX IDE clinical study (n=134), 32 percent of patients presented with TASC II type C or D lesions, 18 percent required contralateral access to the lesion, and 42 percent involved kissing stents at the aortic bifurcation. Clinical data from the Gore VBX FLEX IDE clinical study conducted for FDA approval reflected that the design components of the VBX Stent Graft were resilient both during stenting procedures and over time:

  • 100 percent success rate in device delivery and coverage of target lesions in all study subjects;
  • 100 percent success rate in reducing the target lesion to less than or equal to 30 percent of the original stenosis;
  • Zero change in median length of the device upon deployment; and
  • 96.9 percent primary patency at nine-months, including a 95.3 percent primary patency rate in those patients with TASC II C or D type lesions.

Further, there were no reported incidences of device dislodgement, failures in stent integrity, or device-related serious adverse events through the primary endpoint follow up, meaning no additional costs incurred for either endovascular or surgical stent removal. The VBX Stent Graft does not require pre-dilation, which reduces the number of balloons required, and the longer lengths available reduce the need to use multiple stents for extensive lesions, both of which also contribute to procedural cost savings.
