1. A diametrically adjustable endoprosthesis having a compacted, delivery configuration, the diametrically adjustable endoprosthesis comprising:
a stent-graft including a stent and a base graft secured to the stent, the base graft having a first end and a second end and the stent-graft being self-expanding and exhibiting a self-expansion force, the stent-graft having a maximum diametric expansion limit; and
a controlled expansion element having a continuous wall extending for less than an entire length of the endoprosthesis when the endoprosthesis is in the compacted, delivery configuration, the controlled expansion element having an initial diametric expansion limit and being adjustable to an adjusted diameter through a range of diameters between the initial diametric expansion limit and the maximum diametric expansion limit when placed under an expansion force in addition to the self-expansion force of the stent-graft, the controlled expansion element being configured to maintain the adjusted diameter under physiological conditions following removal of the expansion force and the stent-graft being configured to limit the range of diameters for the adjusted diameter to the maximum diametric expansion limit.
