Sanford Physician helps Develop Groundbreaking Technology for Aneurysm Patients

Device study targeting a larger patient population for condition that affects 24 million people

Corey Teigen with Stent(Fargo, N.D.) -- For eight years Sanford physician Corey Teigen worked on developing a stent graft for abdominal aortic aneurysms (AAA). This investigational device trial has moved to the phase that allows use in patients with this life-threatening condition. The InCraftTM Stent Graft System that Dr. Teigen helped develop will be used on 190 patients at clinical trial sites around the United States and Japan.

Dr. Teigen, Sanford Health Chair for the Department of Interventional Radiology, performed the first AAA repair in the United States with the investigational stent at Sanford Medical Center, Fargo ND on July 20, 2012.

The InCraft endograft is smaller and more flexible than currently approved stents. Patients in need of AAA repair who have smaller blood vessels are one of the target populations of this study. The implant requires a minimally invasive surgery which should mean a faster recovery and shorter hospital stay for the patients.

Dr. Teigen expects the research data will demonstrate the stent’s ease of use and adjustability will make it the treatment of choice for the vast majority of patients in need of an endograft for AAA, including those patients that currently are not deemed suitable candidates for endovascular treatment.

An estimated 24 million people worldwide have abdominal aortic aneurysms. Left untreated, most aneurysms will eventually rupture, with life-threatening consequences. In the U.S. alone, approximately 15-thousand people die every year due to an AAA rupture.
