1. An inflatable structure apparatus comprising:
- a shell having a shell longitudinal axis, a central section and a first neck section, wherein the first neck section has a first neck first end and a first neck second end, and wherein the first neck first end has a first neck first end diameter, and wherein the first neck second end has a first neck second end diameter, and wherein the first neck first end diameter is larger than the first neck second neck diameter, and wherein the first neck first end is adjacent to the central section;
a balloon at least partially inside of the shell, wherein the balloon is fixed in the shell, wherein the balloon has a first cell and second cell in a single cross-section of the inflatable structure, and wherein the balloon has a balloon surface area in the single cross section, and wherein at least 5% of a surface area of the balloon is concentric with the shell;
wherein the shell has a central fluid passage radially inside of the first and second cells of the balloon with respect to the shell longitudinal axis, and wherein a first aperture in the shell is in fluid communication with the central fluid passage but not in fluid communication with the first and second cells of the balloon; and
wherein the first aperture is spaced distally from the first neck second end.

Abstract
An inflatable structure for use in biological lumens and methods of making and using the same are disclosed. The structure can have an inflatable balloon encircled by a shell. The shell can have proximal and distal tapered necks, longitudinally-oriented flutes, and apertures at the proximal and distal ends of the shell. The apertures can be recessed in the flutes in the necks. The shell can also have fiber reinforced walls.
