    providing a balloon having a length of at least about 10 cm, the balloon having a proximal end and a distal end and including a balloon wall formed with a remodelable sheet material harvested from a collagenous tissue, the remodelable sheet material effective to induce cellular invasion and ingrowth into the balloon wall following implantation so that the balloon wall becomes remodeled with patient tissue;

    positioning the balloon such that the distal end is located at a point within the venous vessel of the leg and the proximal end is located at a point exterior to the access opening; and

    passing an amount of fill material into the balloon with said proximal end being located at said point exterior to the access opening.
