Dr. Syde A. Taheri and his team of researchers have made groundbreaking developments in their creation of the Taheri-LaDuca Endovascular System.  In multiple laboratory experiments, they have successfully guided Taheri's invention, an aortic arch stent graft, around the arch of the aorta and into the designated side branch. 

Dr. Taheri believes this is the first time anyone has successfully threaded a stent graft from the groin and into the artery, guided the stent around the arch, then accomplished the difficult task of directing the graft to make a right turn into the side branches of the aorta. 

Taheri, a professor, award-wining inventor and retired surgeon, created the life-saving Talent Thoracic and Abdominal Stent Graft, produced by Medtronic, Inc.  This stent graft has been used in thousands of people worldwide as a minimally invasive method to treating thoracic and abdominal aneurysms, and it is undergoing clinical tests in the United States.  Dr. Taheri says the Aortic Arch Device is an upgrade of the Talent stent graft, which already nets millions of dollars.

More about the Taheri-LaDuca Endovascular System

The Aortic Arch Device will allow a minimally-invasive approach to treating patients at risk of – or suffering from – aortic aneurysms, stroke or trauma.  The aortic arch device is inserted into the aorta, and its design allows it to follow the curve of the aortic arch and right turn into the side branches.  

Currently, the method for repairing an aortic aneurysm is major thoracic surgery under general anesthesia.  It's an operation that the elderly and/or infirmed may not be able to withstand.  But the Taheri-LaDuca Endovascular System would eliminate the need for major thoracic surgery, and it could be conducted under local anesthesia.  It is also being designed to allow doctors to readjust its position once the device is in the artery.
