National first at Mission Health: Surgeons implant first vascular devices in U.S. trial

Press release from Mission Health

ASHEVILLE, N.C. (Dec. 26, 2013) – In late November, two vascular surgeons performed the first two cases in a national endovascular stent-graft trial that could pave the way for the new device receiving Food and Drug Administration (FDA) approval for use in the United States.

The two procedures, performed at Mission Hospital on Nov. 25, 2013, involved placement of the Treovance® Abdominal Stent-Graft with Navitel® Delivery System. Carolina Vascular surgeons, John Henretta, MD, and Mike Douglas, MD, performed the procedures. The device is manufactured by Bolton Medical, which has international operations in Barcelona, Spain, and U.S. operations in Sunrise, Florida.

“Both surgeries went very well,” said Dr. Henretta. “Participating in clinical trials such as this one allows us as surgeons access to safe, effective, cutting-edge medical devices that we can carefully select to fit each individual case precisely. This device in particular is a promising option for patients who come to us with abdominal aortic aneurysms, which are life-threatening conditions. It was easy to use, and I look forward to where this trial will take us.”

The two surgeries mark the beginning of Phase II of the U.S. clinical trial of the stent-graft. Clinical trials are a limited study of a medical device in a select group of carefully monitored patients to determine the safety and efficacy of the device prior to FDA approval. This study involves 150 patients at 30 institutions across the country. The device is already approved for use in Europe. Abdominal stent-grafts, such as this one, are used to repair aneurysms in the abdominal cavity that occur in the vascular system closely related to the heart.

Mission Health participates in numerous clinical trials in a wide variety of medical specialties. Each trial protocol is carefully reviewed and progress is monitored, ensuring patients access to innovative medical devices and procedures close to home.
