An apparatus and associated surgical method for repairing abdominal aortic aneurysms is disclosed. The apparatus includes first and second stent grafts made from a metal form structure in combination with a flexible fabric, and a flexible guidewire detachably attached to the first stent graft. The first stent graft has an upper tubular body which defines an inlet, and a lower bifurcation which includes a first tubular leg defining a first outlet, and a second tubular leg defining a second outlet. The method includes advancing the first stent graft through one iliac artery and deploying it in the aorta, advancing a guidewire engagement device distally through the other iliac artery and pulling the flexible guidewire into the other iliac artery, advancing a guide catheter over the flexible guidewire into the second tubular leg of the first stent graft, replacing the flexible guide wire with a stiffer guide wire through the guide catheter, and advancing a catheter delivery system provided with a second stent graft over the stiffer guide wire into the second tubular leg of the first stent graft.

A bedsheet, a system, and a method for use thereof for elevating at least one leg or heel of the patient lying on a mattress is disclosed. The bedsheet has a plurality of overlapping longitudinally spaced pockets into which a pillow is insertable. The orientation and configuration of the pockets of the bedsheet allows for insertion of the pillow into the bedsheet at a desired location with minimal interruption to or movement of the patient, and holds the inserted pillow in a relatively fixed position relative to the bedsheet. The system includes the bedsheet and the pillow. The method includes placing the bedsheet on the mattress, inserting the pillow into one of the pockets of the bedsheet to create an elevated portion of the bedsheet, and positioning the leg or heel of the patient on top of the elevated portion of the bedsheet.
