1. A prosthesis system for creating a shunt, comprising:
a tubular structure having a radially compressed configuration and a radially expanded configuration;
the tubular structure comprising a laser-cut pattern comprising a plurality of cells that progressively increase in cell sizes from a middle of the tubular structure to axially located end regions of the tubular structure;
wherein the radially expanded configuration of the tubular structure foreshortens in axial length during expansion from the radially compressed configuration to an amount determined by the progressively increasing cell sizes of the laser-cut pattern;
wherein the radially expanded configuration of the tubular structure radially flares axially located end regions to a shape determined by the progressively increasing cell sizes of the laser-cut pattern; and,
a balloon positioned under the tubular structure.
