Gore announced on 27 January 2014 that Himanshu Patel and David Williams, University of Michigan, USA, enrolled the first patient in the Gore TAG Thoracic Branch Endoprosthesis LSA Feasibility Study, a US-based, multicentre feasibility trial. The FDA approved the investigational device exemption (IDE) trial for the Gore TAG Thoracic Branch Endoprosthesis in the treatment of thoracic aortic aneurysms that require coverage of the left subclavian artery (LSA).
“Thoracic aortic aneurysms that encroach on the left subclavian artery make treating these challenging anatomies very difficult, leaving physicians no choice but to use more invasive surgical techniques or to cover the branch vessel,” said Patel. “Using the Gore TAG Thoracic Branch Endoprosthesis, we were able to successfully treat the first patient in the study using endovascular means only. These results demonstrate the feasibility of using branched stent grafts to treat aortic aneurysms that involve the left subclavian artery.”
“With this study, we hope to demonstrate that the Gore device allows physicians to safely treat aortic aneurysms near the aortic arch while maintaining blood flow to all branch vessels using endovascular techniques,” said Michael Dake, principal investigator and Thelma and Henry Doelger Professor of Cardiovascular Surgery at the Stanford School of Medicine, Stanford, USA. “Gore’s device will reduce the need for invasive surgical procedures commonly required today, thus reducing the complications associated with treatment of this complex disease.”
The Gore TAG Thoracic Branch Endoprosthesis builds on more than 15 years of Gore experience in aortic innovation. Designed for long-term durability, the device allows for femoral-only access over a pre-positioned branch guidewire for ease of implantation. The device also features the Carmeda BioActive Surface (CBAS Heparin Surface) for sustained antithrombotic bioactivity, as is present on many of Gore’s peripheral vascular products.
“Gore is committed to designing innovative solutions that treat challenging patient populations. Long-term durability and patient outcomes are the cornerstone of our research and development,” said Ryan Takeuchi, Aortic Business unit leader at Gore. “We dedicated significant time and effort into the development of our thoracic branch technology and it has become the foundation of our aortic branch portfolio. Earlier this year, we introduced our first branched device with the Gore Excluder Iliac Branch Endoprosthesis with much clinical success across Europe. Now with our Gore TAG Thoracic Branch Endoprosthesis, physicians will be able to treat a subset of patients that could not be considered for total endovascular repair in the past.”
