Abstract
The present invention provides a guidewire placement system for delivery of an aneurysm graft limb. The invention is directed toward placement of grafts in abdominal aortic aneurysms where delivery of a contra-lateral limb is heretofore particularly difficult. The present invention provides external tubing which may be steered along with guide tubing having wire loops at the distal end thereof. The design of the external tubing and the guide tubing allow a contra-lateral guidewire to be directed toward and placed within a graft of the aneurysm. This allows for subsequent placement of a contra-lateral limb in an efficient and minimally invasive manner.
