Claim 0:
1. A method for treating a patient having a vessel, the method comprising:
receiving a delivery device in an internal volume of a variable occlusion element, the internal volume enclosed by an inner member and opening to a proximal opening disposed at a proximal end of a balloon body and a distal opening disposed at a distal end of the balloon body, the delivery device positioning the variable occlusion element in a lumen of the vessel;
enlarging a toroidal volume as the variable occlusion element inflates, the toroidal volume enclosed by an outer membrane of the balloon body, the outer membrane sealed to the inner member at the proximal end and the distal end; and
shrinking the toroidal volume as the variable occlusion element deflates, the toroidal volume enlarging or shrinking as the variable occlusion element inflates or deflates between a plurality of occlusion states, each of the plurality of occlusion states including an occlusion factor corresponding to a percentage of a cross-sectional area of the lumen of the vessel occluded by the variable occlusion element.
