One high-risk patient had a fatal myocardial infarction three days after the surgery. However, almost 90 percent of the patients in the study were discharged within two or three days of the surgery, compared with 5.8 days in patients undergoing the open procedure. At a mean follow-up period of eight months, all of these patients were doing well. During the surgery, a catheter containing a collapsed polyester tube is inserted into the patient's femoral artery and moved to the site of the aneurysm. Then, a spring-type attachment system hooks the tube to the inside walls of the artery on either end of the aneurysm and is anchored into place.
Blood is able to flow through the implant, cutting off the supply of blood to the aneurysm.
