Aneurysm Surgery / Endovascular Stenting - CSA offers a new technology to allow qualifying patients to have aneurysm repair with a minimally invasive thoracic endoprosthesis device. The function of the endoprosthesis is to internally reline the thoracic aorta and isolate the diseased segment from blood circulation. The device is inserted by a catheter delivery technique through a small incision in the patient’s groin.
