Abstract
The invention includes an expandable stent having a tubular shape when expanded, the shape including a portion t where the stent radius grows with stent length so that the growth in the portion is constant conductance growth or near-constant conductance growth. The invention includes sheaths that will encase the stent to restrict the growth of the stent to the desired expanded shape. The invention also includes expandable stent balloons that expand the stent to the desired shape configuration with constant or near constant conductance portion. The balloons can include a similar sheath or sleeve to restrict the balloon's growth to the desired shape. The stent radius growth can be piecewise, and is not necessarily 4order growth, but can be such that r/l is a constant in the portion, where n>4.
