Abstract
Abstract A plurality of expandable and deformable intraluminal vascular grafts (70) are expanded within a blood vessel by an angioplasty balloon associated with a catheter to dilate and expand the lumen of a blood vessel. The grafts (70) may be thin-- walled tubular members having a plurality of slots (82) disposed substantially parallel to the longitudinal axis of the tubular members (71), and adjacent grafts (70) are flexibly connected by at least one connector member (100).
