STENT-GRAFT WITH POSITIONING ANCHOR

摘要

A positioning anchor (10) is provided for a stent-graft (40) for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit (22). Arms (15, 16, 18) extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft (40) coupled to the anchor. The anchor is most preferably formed with two walls (20, 30) having a void (35) there between which can be filled with fixation media (M) to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.
