This method is a potentially lower risk alternative to standard surgery because it eliminates the need for a large incision by allowing for the repair of the aneurysm through the inside of the artery. Also, by limiting the extent of surgery, hospital stays can be reduced hopefully resulting in lower cost. The device is inserted into an artery in the patient's groin and moved to the site of the aneurysm. The device contains a tubular expanded Teflon graft supported by a metallic stent. Once inside the aneurysm, the graft is deployed and is held in place by the metallic framework.
Blood then flows through the implant instead of the aneurysm.
The multi-center study will include 118 test patients who will receive the new surgical treatment and 118 control patients who will undergo conventional surgery. About 30 patients will be entered into the study at UPMC Health System.
